An antianginal and class III antiarrhythmic drug. It increases the duration of ventricular and atrial muscle action by inhibiting POTASSIUM CHANNELS and VOLTAGE-GATED SODIUM CHANNELS. There is a resulting decrease in heart rate and in vascular resistance.
Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade.
Compounds that contain a BENZENE ring fused to a furan ring.
Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.
Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.
An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).
An adrenergic beta-antagonist that is used in the treatment of life-threatening arrhythmias.
A hypermetabolic syndrome caused by excess THYROID HORMONES which may come from endogenous or exogenous sources. The endogenous source of hormone may be thyroid HYPERPLASIA; THYROID NEOPLASMS; or hormone-producing extrathyroidal tissue. Thyrotoxicosis is characterized by NERVOUSNESS; TACHYCARDIA; FATIGUE; WEIGHT LOSS; heat intolerance; and excessive SWEATING.
A potentially lethal cardiac arrhythmia that is characterized by uncoordinated extremely rapid firing of electrical impulses (400-600/min) in HEART VENTRICLES. Such asynchronous ventricular quivering or fibrillation prevents any effective cardiac output and results in unconsciousness (SYNCOPE). It is one of the major electrocardiographic patterns seen with CARDIAC ARREST.
Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.
An electrical current applied to the HEART to terminate a disturbance of its rhythm, ARRHYTHMIAS, CARDIAC. (Stedman, 25th ed)
An antiarrhythmia agent that is particularly effective in ventricular arrhythmias. It also has weak beta-blocking activity.
Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.
Abnormally rapid heartbeats with sudden onset and cessation.
A rare form of supraventricular tachycardia caused by automatic, not reentrant, conduction initiated from sites at the atrioventricular junction, but not the ATRIOVENTRICULAR NODE. It usually occurs during myocardial infarction, after heart surgery, or in digitalis intoxication with a HEART RATE ranging from 140 to 250 beats per minute.
A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA.
Blood tests used to evaluate the functioning of the thyroid gland.
The hollow, muscular organ that maintains the circulation of the blood.
A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.
Tumors or cancer of the THYROID GLAND.
Pathological processes involving the THYROID GLAND.
Natural hormones secreted by the THYROID GLAND, such as THYROXINE, and their synthetic analogs.

Effects of cycloprotobuxine-A on atrial fibrillation. (1/719)

AIM: To study the effects of cycloprotobuxine-A (Cyc-A) on atrial fibrillation. METHODS: Atrial fibrillations in vivo and in vitro were induced by arrhythmogenic drugs. Action potentials were measured by the standard microelectrode technique. RESULTS: Cyc-A, similar to or slightly stronger than amiodarone (Ami), decreased incidences of atrial fibrillation elicited by CaCl2-acetylcholine in mice and increased doses of aconitine, ouabain, or adrenaline to elicit atrial fibrillation in isolated guinea pig atria. Cyc-A 0.3-100 mumol.L-1 decreased the normal automaticity and 0.3-30 mumol.L-1 attenuated or almost abolished the isoprenaline-induced abnormal increase in automaticity in sinus nodal cells. In isolated left atria, Cyc-A 0.3-30 mumol.L-1 inhibited the abnormal rhythmic activity elicited by adrenaline, prolonged action potential duration (APD) and effective refractory period, and reduced excitability. At 3-30 mumol.L-1, Cyc-A also decreased the maximal velocity of depolarization (Vmax). Cyc-A antagonized the acetylcholine-induced shortening of APD. These electrophysiologic effects were similar to those of amiodarone, but Ami did not affect the Vmax. CONCLUSION: Cyc-A produces a protective effect against experimental atrial fibrillation via a prolongation of repolarization, a decease of automaticity, and an inhibition of excitability.  (+info)

Retinal stimulates ATP hydrolysis by purified and reconstituted ABCR, the photoreceptor-specific ATP-binding cassette transporter responsible for Stargardt disease. (2/719)

Many substrates for P-glycoprotein, an ABC transporter that mediates multidrug resistance in mammalian cells, have been shown to stimulate its ATPase activity in vitro. In the present study, we used this property as a criterion to search for natural and artificial substrates and/or allosteric regulators of ABCR, the rod photoreceptor-specific ABC transporter responsible for Stargardt disease, an early onset macular degeneration. ABCR was immunoaffinity purified to apparent homogeneity from bovine rod outer segments and reconstituted into liposomes. All-trans-retinal, a candidate ligand, stimulates the ATPase activity of ABCR 3-4-fold, with a half-maximal effect at 10-15 microM. 11-cis- and 13-cis-retinal show similar activity. All-trans-retinal stimulates the ATPase activity of ABCR with Michaelis-Menten behavior indicative of simple noncooperative binding that is associated with a rate-limiting enzyme-substrate intermediate in the pathway of ATP hydrolysis. Among 37 structurally diverse non-retinoid compounds, including nine previously characterized substrates or sensitizers of P-glycoprotein, only four show significant ATPase stimulation when tested at 20 microM. The dose-response curves of these four compounds are indicative of multiple binding sites and/or modes of interaction with ABCR. Two of these compounds, amiodarone and digitonin, can act synergistically with all-trans-retinal, implying that they interact with a site or sites on ABCR different from the one with which all-trans-retinal interacts. Unlike retinal, amiodarone appears to interact with both free and ATP-bound ABCR. Together with clinical observations on Stargardt disease and the localization of ABCR to rod outer segment disc membranes, these data suggest that retinoids, and most likely retinal, are the natural substrates for transport by ABCR in rod outer segments. These observations have significant implications for understanding the visual cycle and the pathogenesis of Stargardt disease and for the identification of compounds that could modify the natural history of Stargardt disease or other retinopathies associated with impaired ABCR function.  (+info)

Fetal tachycardias: management and outcome of 127 consecutive cases. (3/719)

OBJECTIVE: To review the management and outcome of fetal tachycardia, and to determine the problems encountered with various treatment protocols. STUDY DESIGN: Retrospective analysis. SUBJECTS: 127 consecutive fetuses with a tachycardia presenting between 1980 and 1996 to a single tertiary centre for fetal cardiology. The median gestational age at presentation was 32 weeks (range 18 to 42). RESULTS: 105 fetuses had a supraventricular tachycardia and 22 had atrial flutter. Overall, 52 fetuses were hydropic and 75 non-hydropic. Prenatal control of the tachycardia was achieved in 83% of treated non-hydropic fetuses compared with 66% of the treated hydropic fetuses. Digoxin monotherapy converted most (62%) of the treated non-hydropic fetuses, and 96% survived through the neonatal period. First line drug treatment for hydropic fetuses was more diverse, including digoxin (n = 5), digoxin plus verapamil (n = 14), and flecainide (n = 27). The response rates to these drugs were 20%, 57%, and 59%, respectively, confirming that digoxin monotherapy is a poor choice for the hydropic fetus. Response to flecainide was faster than to the other drugs. Direct fetal treatment was used in four fetuses, of whom two survived. Overall, 73% (n = 38) of the hydropic fetuses survived. Postnatally, 4% of the non-hydropic group had ECG evidence of pre-excitation, compared with 16% of the hydropic group; 57% of non-hydropic fetuses were treated with long term anti-arrhythmics compared with 79% of hydropic fetuses. CONCLUSIONS: Non-hydropic fetuses with tachycardias have a very good prognosis with transplacental treatment. Most arrhythmias associated with fetal hydrops can be controlled with transplacental treatment, but the mortality in this group is 27%. At present, there is no ideal treatment protocol for these fetuses and a large prospective multicentre trial is required to optimise treatment of both hydropic and non-hydropic fetuses.  (+info)

Electrophysiologic effects of chronic amiodarone therapy and hypothyroidism, alone and in combination, on guinea pig ventricular myocytes. (4/719)

Amiodarone is a widely used antiarrhythmic drug, the mechanisms of action of which remain incompletely understood. Indirect evidence suggests that the class III properties of amiodarone may be mediated by cardiac antithyroid effects. We sought to determine whether the effects of chronic amiodarone on repolarization in guinea pig hearts can be attributed to an antithyroid action by studying the changes in dofetilide-sensitive rapid (IKr) and dofetilide-resistant slow (IKs) delayed rectifier currents, inward rectifier K+ current (IK1), and action potentials of ventricular myocytes from five groups of guinea pigs: control, hypothyroid, amiodarone-treated for 7 days, hypothyroid plus amiodarone, and vehicle (dimethyl sulfoxide) treated. IKs was reduced by amiodarone (to 61% of control, P <.05, at 50 mV) but was more strongly reduced by hypothyroidism (to 35% of control, P <.01, 50 mV). Amiodarone significantly reduced IKr and IK1 (by 55 and 64% at 10 mV and -50 mV, respectively), which were unaffected by hypothyroidism. Amiodarone alone and hypothyroidism alone had similar action potential-prolonging actions. Hypothyroid animals treated with amiodarone showed a combination of ionic effects (strong IKs reduction, similar to hypothyroidism alone; reduced IKr and IK1, similar to amiodarone alone), along with action potential prolongation significantly greater than that caused by either intervention alone. We conclude that chronic amiodarone and hypothyroidism have different effects on ionic currents and that their combination prolongs action potential duration to a greater extent than either alone in guinea pig hearts, suggesting that the class III actions of amiodarone are not mediated by a cardiac hypothyroid state.  (+info)

Amiodarone versus propafenone for conversion of chronic atrial fibrillation: results of a randomized, controlled study. (5/719)

OBJECTIVES: The purpose of this study was to investigate the efficacy and safety of amiodarone and propafenone in the conversion of chronic atrial fibrillation in a prospective, randomized, placebo-controlled study. BACKGROUND: The effectiveness of amiodarone and propafenone in the treatment of patients with chronic atrial fibrillation has not been adequately studied. METHODS: One hundred one patients (48 men, mean age 64 +/- 9 years) with atrial fibrillation lasting >3 weeks participated in the study. Thirty-four patients received amiodarone (300 mg intravenously over 1 h, followed by 20 mg/kg over the next 24 h plus 600 mg orally, in three doses, for 1 week, then 400 mg/day orally, for three weeks), 32 received propafenone (2 mg/kg intravenously over 15 min, followed by 10 mg/kg over 24 h and then 450 mg/day orally, for one month) and the remaining 35 served as control subjects. All patients received digoxin and anticoagulant treatment as indicated (International Normalized Ratio 2 to 3). RESULTS: Conversion to sinus rhythm was achieved in 16 (47.05%) patients who received amiodarone, in 13 (40.62%) who received propafenone and in none of the control subjects (p < 0.001 for both groups vs. control subjects). Those who converted had smaller atria than those who did not and atrial fibrillation of shorter duration in both the amiodarone and propafenone groups. Treatment was discontinued in one patient of the propafenone group because of significant QRS widening. CONCLUSIONS: Amiodarone and propafenone appear to be safe and equally effective in the termination of chronic atrial fibrillation. Left atrial diameter and arrhythmia duration are independent predictors of conversion.  (+info)

Effect of intravenous amiodarone on electrophysiologic variables and on the modes of termination of atrioventricular reciprocating tachycardia in Wolff-Parkinson-White syndrome. (6/719)

Atrioventricular reciprocating tachycardia (AVRT) associated with the Wolff-Parkinson-White (WPW) syndrome, sometimes terminates spontaneously, generally sustains and eventually becomes drug resistant. Amiodarone is a potent antiarrhythmic drug that is sometimes effective in patients with AVRT which is resistant to conventional antiarrhythmic drugs. However, systematic studies concerning the effects of amiodarone on AVRT have not been reported. This study evaluated the effects of intravenous amiodarone on electrophysiologic variables, and on the sites and the modes of termination of AVRT. Fifteen WPW patients were studied. Nine had overt, and 6 had concealed WPW syndrome. Measurements of electrophysiologic variables and the induction of AVRT were performed by atrial and/or ventricular programmed stimulations. Amiodarone was then administered at a dose of 5 mg/kg over 5 min. The effective refractory periods (ERP) of the atrial, atrioventricular node, ventricular and accessory pathway were increased significantly by amiodarone. The conduction times of all the components were significantly lengthened by amiodarone, except for the His-ventricular (HV) interval in concealed WPW patients. AVRT was induced in all patients, and was terminated by amiodarone in 12 of 13 patients with sustained AVRT. After amiodarone, AVRT was induced in 9 patients. Spontaneous termination was observed 11 times in 3 of the 9 patients in whom AVRT was still induced. In these cases, the modes and sites of termination were the same as during the baseline state. The ERPs and conduction times of all components of AVRT, except the HV interval, were significantly lengthened by amiodarone. Amiodarone is efficacious for terminating AVRT wherever weak links exist. However, sites of spontaneous termination are not significantly affected by amiodarone.  (+info)

Comparison of sotalol with amiodarone for long-term treatment of spontaneous sustained ventricular tachyarrhythmia based on coronary artery disease. (7/719)

AIM: To compare the efficacy of sotalol versus amiodarone for long-term treatment of ventricular tachyarrhythmias. METHODS: Patients (n=75) with spontaneous, sustained ventricular tachyarrhythmias secondary to remote myocardial infarction were studied. After intravenous electrophysiological testing, both sotalol and amiodarone were predicted to be ineffective in 50 (67%) patients. Five patients were excluded. Forty-five patients were randomized to receive sotalol (n=22) or amiodarone (n=23) for maintenance therapy. The primary outcome variable was the time to first recurrence of sustained ventricular tachyarrhythmia. RESULTS: At 36 months. 75% of those allocated sotalol remained free of ventricular tachyarrhythmia compared with 38% of those allocated amiodarone (P=0.05). On multivariate analysis the risk of recurrence of ventricular tachyarrhythmia for patients on amiodarone was 5.9 times higher (P=0.008) than that for patients on sotalol. CONCLUSION: Sotalol is superior to amiodarone for long-term treatment of ventricular tachyarrhythmia secondary to coronary artery disease when both drugs have been predicted to be ineffective at intravenous electrophysiological testing. Randomized trials in larger numbers of patients with ventricular tachyarrhythmia need to be performed comparing the two agents directly.  (+info)

Amiodarone compared with iodine exhibits a potent and persistent inhibitory effect on TSH-stimulated cAMP production in vitro: a possible mechanism to explain amiodarone-induced hypothyroidism. (8/719)

Amiodarone (AMD) is a powerful anti-arrhythmic drug used for the treatment of a wide variety of cardiac arrhythmias and its most striking feature is its high iodine content. Thyroid dysfunction is a limiting side-effect of the drug and both AMD-induced hypothyroidism (AIH) and AMD-induced thyrotoxicosis (AIT) are reported. To examine the hypothesis that altered bioavailability of iodine is a contributing event in the pathogenesis of AIH, we compared the effects of AMD and inorganic iodine in vitro on events involved in the process of thyroid autoregulation. FRTL-5 cells and JP26 CHO cells (transfected with the human TSH receptor) were exposed to AMD or NaI in the presence of TSH, and cAMP production was measured as an indicator of cellular function. Forskolin and cholera toxin were also used to determine the possible target sites of AMD and iodide. Our results indicated that there was a difference between the effects of AMD versus those of physiological doses of iodide. The inhibitory effects of AMD occurred at lower concentrations of iodide than those seen in the NaI-treated cells. The effects of AMD were irreversible indicating a possible persistence of the Wolff-Chaikoff effect due to a constant high intracellular iodide level. The inhibitory effects of AMD (also seen at supraphysiological doses of iodide) were partially overcome by forskolin but not by cholera toxin indicating an effect on TSH receptor interactions with the other signal transduction elements such as G proteins and adenylate cyclase. The persistence of the Wolff-Chaikoff effect through loss of autoregulation may be a mechanism of the observed hypothyroidism in some patients taking AMD. The combined effects of the constant release of iodide together with the drug toxicity may be the mechanism for the observed effects.  (+info)

Following oral administration in man, amiodarone hydrochloride is slowly and variably absorbed. The bioavailability of amiodarone hydrochloride is approximately 50%, but has varied between 35% and 65% in various studies. Maximum plasma concentrations are attained 3 to 7 hours after a single dose. Despite this, the onset of action may occur in 2 to 3 days, but more commonly takes 1 to 3 weeks, even with loading doses. Plasma concentrations with chronic dosing at 100 mg/day to 600 mg/day are approximately dose proportional, with a mean 0.5 mg/L increase for each 100 mg/day. These means, however, include considerable individual variability. Food increases the rate and extent of absorption of amiodarone hydrochloride. The effects of food upon the bioavailability of amiodarone hydrochloride have been studied in 30 healthy subjects who received a single 600-mg dose immediately after consuming a high-fat meal and following an overnight fast. The area under the plasma concentration-time curve (AUC) and ...
Hyperthyroidism or hypothyroidism may occur in patients taking amiodarone.2 Amiodarone can interfere with thyroid function due to iodine in the medicine blocking the conversion of T4 to T3.2 A 200 mg tablet of amiodarone will yield approximately 40 times the recommended 150 microgram daily intake of iodine in a patient in steady state metabolism.5, 10 Altered thyroid function tests in the first three months of treatment are common.4. Hyperthyroidism is reported to be the most frequent amiodarone-induced adverse effect in New Zealand recorded by the Centre for Adverse Reaction Monitoring (CARM).8 This can develop rapidly and patients may present with a new arrhythmia.8 If patients taking amiodarone develop tachycardia or atrial fibrillation their thyroid function should be retested.8 If a patient has elevated T3 and T4 levels with very low or undetectable TSH levels this is consistent with thyrotoxicosis and amiodarone should be temporarily withdrawn.8 Carbimazole may be initiated to block ...
Amiodarone is a potent antiarrhythmic agent that is used to treat ventricular arrhythmias and atrial fibrillation. The drug prevents the recurrence of life-threatening ventricular arrhythmias and produces a modest reduction of sudden deaths in high-risk patients. Amiodarone is more effective than sotalol or propafenone in preventing recurrent atrial fibrillation in patients for whom a rhythm-control strategy is chosen. When long-term amiodarone therapy is used, potential drug toxicity and interactions must be considered. The dosage of amiodarone should be kept at the lowest effective level. In patients who also are taking digoxin and warfarin, physicians must pay close attention to digoxin levels and prothrombin time, keeping in mind that the effects of interaction with amiodarone do not peak until seven weeks after the initiation of concomitant therapy. Laboratory studies to assess liver and thyroid function should be performed at least every six months.
BACKGROUND: In the ENGAGE AF-TIMI 48 trial, the higher-dose edoxaban (HDE) regimen had a similar incidence of ischaemic stroke compared with warfarin, whereas a higher incidence was observed with the lower-dose regimen (LDE). Amiodarone increases edoxaban plasma levels via P-glycoprotein inhibition. The current pre-specified exploratory analysis was performed to determine the effect of amiodarone on the relative efficacy and safety profile of edoxaban.. METHODS AND RESULTS: At randomization, 2492 patients (11.8%) were receiving amiodarone. The primary efficacy endpoint of stroke or systemic embolic event was significantly lower with LDE compared with warfarin in amiodarone treated patients vs. patients not on amiodarone (hazard ratio [HR] 0.60, 95% confidence intervals [CIs] 0.36-0.99 and HR 1.20, 95% CI 1.03-1.40, respectively; P interaction ,0.01). In patients randomized to HDE, no such interaction for efficacy was observed (HR 0.73, 95% CI 0.46-1.17 vs. HR 0.89, 95% CI 0.75-1.05, P ...
Title: Dronedarone: A Safety Comparison to Amiodarone. VOLUME: 5 ISSUE: 3. Author(s):James R. Clem, Debra K. Farver, Janet R. Fischer and Thomas J. Johnson. Affiliation:South Dakota State University College of Pharmacy, 4801 North Career Avenue, Sioux Falls, SD 57107, USA.. Keywords:Dronedarone, SR 33589, amiodarone, atrial fibrillation, safety. Abstract: Dronedarone is an oral Class III antiarrhythmic agent which was recently approved by the US Food and Drug Administration for use in nonpermanent atrial fibrillation. Structurally similar to amiodarone, dronedarone is a benzofuran derivative but it lacks the iodine moiety attached to amiodarone. Based upon the investigational clinical trials to date, it appears that dronedarone has an established efficacy when compared to placebo along with exhibiting a minimal adverse effect profile. The efficacy of dronedarone will need to be further evaluated in comparison trials with established antiarrhythmics for atrial fibrillation. The adverse profile of ...
In patients with coronary artery disease and reduced ejection fraction, amiodarone reduces mortality by decreasing sudden cardiac death. Since the latter may be triggered by coronary artery thrombosis as much as ventricular arrhythmias, amiodarone might interfere with tissue factor (TF) expression and thrombus formation. Clinically relevant plasma concentrations of amiodarone inhibited TF activity and carotid artery thrombus formation in a mouse photo-chemical injury model in vivo (n = 5; p , 0.035; Figure 1). In human endothelial and vascular smooth muscle cells, amiodarone inhibited tumor necrosis factor-α and thrombin induced TF protein expression (n = 4; p , 0.001) as well as surface activity (n = 4; p , 0.0001). Tissue factor pathway inhibitor was not affected (n = 5; p = NS). Amiodarone lacking iodine as well as the main metabolite of amiodarone, N-monodesethylamiodarone, inhibited TF expression (n = 4; p, 0.01). Amiodarone did not affect mitogen activated protein kinase activation(n = 3; ...

Amiodarone is considered a class III antiarrhythmic drug, but it possesses electrophysiologic characteristics of all four Vaughan Williams classes. Like class I drugs, amiodarone blocks sodium channels at rapid pacing frequencies, and like class II drugs, amiodarone exerts a noncompetitive antisympathetic action. One of its main effects, with prolonged administration, is to lengthen the cardiac action potential, a class III effect. The negative chronotropic effect of amiodarone in nodal tissues is similar to the effect of class IV drugs. In addition to blocking sodium channels, amiodarone blocks myocardial potassium channels, which contributes to slowing of conduction and prolongation of refractoriness. The antisympathetic action and the block of calcium and potassium channels are responsible for the negative dromotropic effects on the sinus node and for the slowing of conduction and prolongation of refractoriness in the atrioventricular (AV) node. Its vasodilatory action can decrease cardiac ...
A number of studies have demonstrated an improvement in left ventricular EF or clinical heart failure end points with amiodarone therapy.1 2 3 Cleland et al1 reported an improvement in central hemodynamics with amiodarone therapy in patients with heart failure, but their study was small and nonrandomized. Hamer et al2 found an increase in both EF and exercise tolerance in a prospective, randomized trial. However, both of these studies were small, and harder clinical end points were not examined. Furthermore, unlike the present study, background vasodilator therapy was not consistently used.. The most important previous study of amiodarone in patients with CHF is the Grupo de Estudio de la Sobrevida en la Insuficiencia Cardiaca en Argentina (GESICA) trial.3 In GESICA, in contrast to the Veterans Affairs trial, all-cause mortality was reduced by 28% (P,.03), and sudden death mortality was reduced by 27% (P=.056). For comparison with the present study, the most relevant findings from GESICA were ...
The effect of long-term treatment with amiodarone on patients with Chagas disease has seldom been reported. This nonrandomized observational study attempted to analyze the follow-up of patients with Chagas disease regarding their clinical evolution, thyroid dysfunction, and goiter. We compared 72 patients with long-term use (11 +/- 5 years) of amiodarone, including 22 patients who developed goiter, to 33 patients who did not use amiodarone, followed-up for 2 to 20 years (7 +/- 11 years). Follow-up of 72 patients for 9 +/- 5.4 years with periodic cardiac and thyroid function evaluations showed that only 26 maintained normal serum thyrotropin (TSH) levels; 24 presented with elevated levels; 4 had low levels, and 18 patients presented with fluctuations of TSH level. Among the 22 patients with goiter, only 3 (14%) patients maintained normal TSH, 8 (36%) had elevated TSH, 2 (9%) had low TSH, and 9 (41%) patients presented with fluctuating serum TSH levels. Most individuals remained clinically ...
Amiodarone (AMD) is a potent antiarrhythmic drug with high efficacy for treating atrial fibrillation and tachycardia. The pharmacologic profile of AMD is complex. AMD possesses biophysical characteristics of all of class I, II, III, and IV agents. Despite its adverse side effects, AMD remains the most commonly prescribed antiarrhythmic drug. AMD was described to prolong the QT interval and can lead to torsades de pointes. Our goal was to study the effects of AMD on peak and late sodium currents (INa,P and INa,L) and determine whether these effects change as AMD is metabolized into N-desethylamiodarone (DES). We hypothesized that AMD and DES block both INa,P and INa,L with similar profiles due to structural similarities. Given the inherent small amounts of INa,L in NaV1.5, we screened AMD and DES against the Long QT-3-causing mutation, ΔKPQ, to better detect any drug-mediated effect on INa,L. Our results show that AMD and DES do not affect WT or ΔKPQ activation; however, both drugs altered the apparent
A amiodarona, usada no tratamento de arritmias cardíacas, está associada com disfunção tiroideana. Não existem relatos sobre sua freqüência no sudeste do Brasil e nem estudos avaliando a utilidade de scores clínicos para o diagnóstico de anormalidades tiroideanas nesses pacientes. Este estudo visou determinar a prevalência de disfunções tiroideanas induzidas pela amiodarona numa amostra representativa de um centro teciário, para estudar as condições associadas a esta disfunção e para avaliar a confiabilidade de scores clínicos para hipo e hipertiroidismo. Avaliação clínica e laboratorial foi realizada em 195 pacientes em uso de amiodarona; desses, 2,1% tinha hipertiroidismo, 25,1% hipotiroidismo e 9,2% tinha apenas um T4 elevado. Considerando as variáveis pesquisadas de disfunção tiroideana, a autoimunidade tiroideana estava associada positivamente (OR 4,8; p= 0,02), e o sexo masculino teve uma tendência para associação positiva (OR 1,86; p= 0,06). Os scores clínicos ...
Standard dual chamber pacing was first used as adjunctive treatment for severe congestive heart failure in the early 1990s.1 It was proposed that a short atrioventricular delay reduced presystolic mitral regurgitation.2,3 It also may correct chronotropic incompetence and protect against fatal bradyarrhythmias.. We performed a randomised study to test whether DDDR pacing with optimised atrioventricular (AV) delay and reversal of drug induced bradycardia by rate responsive pacing was beneficial in heart failure patients who were receiving combined treatment with amiodarone and β blockers as empirical prophylaxis against sudden tachyarrhythmic death.4. In 82 patients with severe heart failure submitted for heart transplantation and without a conventional pacemaker indication between 1996 and 1998 (85% male; 52% idiopathic dilated cardiomyopathy), treatment with low dose amiodarone (1000 mg/week) plus titrated doses of carvedilol (target 50 mg/day) was instituted. In addition, a dual chamber ...
The long QT syndrome is characterized by prolongation of the QT interval and by the occurrence of life-threatening tachyarrhythmias.1 It can be familial or acquired.

Introduction: Class I antiarrhythmic drugs increase duration of the excitable gap (EG) during typical atrial flutter whereas intravenous class III drugs decrease the EG. The effect of chronic oral amiodarone therapy on the EG is unknown. Methods and Results: EG was prospectively determined by introducing a premature stimulus and analyzing the response pattern during typical atrial flutter in 30 patients without antiarrhythmic drugs and in 20 patients under chronic oral amiodarone therapy. EG was calculated by the difference between the longest coupling interval leading to resetting and the effective atrial refractory period (EARP). A fully EG was defined by the portion of EG where the response curve of the return cycles was flat. A partially EG was defined by the portion of EG where the return cycle increases while coupling interval decreases. A resetting response curve was constructed by plotting the duration of the return cycle against the value of the coupling interval. Cycle length (CL; 222 ...
Department of Radiology, University of Wisconsin - Madison, 600 Highland Ave,SC E1/372, Madison, WI, 53792, Wisconsin, USA1 and department of Diagnostic Radiology and Medical Physics, University Hospi- Given the history of this patient, which also included the use of amiodarone, drug induced lung toxicity - amiodarone pneumonitis - was suspected. The diagnosis was validated by trans-bronchial biopsy. Amiodarone treatment was stopped and treat-ment with corticosteroid treatment was initiated. Amiodarone is a class III anti-arrhythmic drug used for treatment of refractory cardiac tachyarrhyth- mias. It accumulates in the liver and lung, and may lead to potentially fatal pulmonary toxicity in 5% of Amiodarone pneumonitis was first described in 1980. Its prevalence in patients treated with amiodarone reached up to 15%. With higher age and higher dosage of amiodarone, the risk of amiodarone pneu- monitis increases. Due to its long tissue half life, both onset of lung toxicity and clearing following ...

4. Ive been on amiodarone for over a year. It works for me and keeps me out of A-Fib. But Im worried about the toxic side effects. What should I do?. You are correct to be concerned about toxic effects. Amiodarone is considered one of the most effective antiarrhythmic meds, but its also one of the most toxic. It may affect your lungs, eyes, thyroid, liver, skin, heart, and nervous system.. Also, amiodarone has a long half-life. It is retained in the body for up to 45 days after the drug has been discontinued.. (Be advised that a newer drug dronedarone (brand name Multaq) is now on the market and may be a good substitute for amiodarone. Dronedarone may not be quite as effective as amiodarone, but is much safer. However, some studies indicate that dronedarone may have problems.). If you are taking amiodarone, you should by monitored and tested frequently and scrupulously for damage to your organ systems (your doctor may already be doing this). You should keep copies of any tests. Whats ...
The HRCT findings of chemotherapeutic drug-induced lung disease reflect the histologic findings17. Interstitial pneumonitis and fibrosis result in ground-glass opacities, focal areas of consolidation and irregular linear opacities that tend to involve the lower zones of the lungs. Acute respiratory distress syndrome results in bilateral predominantly dependent air-space consolidation with onset occurring within days of chemotherapy administration. Approximately 6% of individuals receiving amiodarone develop pulmonary toxicity18. The most common HRCT finding of amiodarone toxicity is diffuse interstitial thickening or less commonly as nodular areas of subpleural consolidation. Amiodarone is an iodine containing compound; therefore, parenchymal lesions often show high attenuation with a range from 82 to 174 HU. Although this finding is helpful in suggesting amiodarone-induced pulmonary toxicity, it is not pathognomonic. Nitrofurantoin toxicity on HRCT shows air-space consolidation with a basilar ...

Amiodarone is a commonly used anti-arrhythmic agent, with well-recognized chronic toxicity. Less well known is amiodarones potential to cause acute lung damage, which can be severe or, occasionally, life-threatening. Lungs that have already been exposed to physical insults, such as the lungs of patients undergoing cardiac surgery, are particularly susceptible to acute pulmonary toxicity (APT). Unfortunately, cardiac surgery is one of the clinical scenarios in which amiodarone is most commonly used. After reviewing the data, and even in the context of difficulties and discrepancies in the existing literature, we contend that there is sufficient evidence of amiodarones potentially serious side-effect profile in surgical ICU patients to advise continued caution in its use with this severely ill patient group. We suggest that amiodarone has a potentially important, though underrecognized, role in inducing an APT/ARDS in some patients, such as those undergoing cardiac surgery. We also provide a hypothesis
Amiodarone is a unique and complex drug with multiple effects. It is difficult to determine which of its effects might be related to our findings. In contrast to many antiarrhythmic drugs, amiodarone has been effective in several patient groups and has not been associated with increased mortality ([8]). Its most obvious direct electrophysiologic effect is prolongation of the action potential duration and repolarization time (class III antiarrhythmic effect). Despite an association of QT prolongation with malignant ventricular arrhythmias, amiodarone is the antiarrhythmic agent that has the least proarrhythmic effect, possibly due to more uniform prolongation of myocardial repolarization resulting in a decrease of QT dispersion ([15-18]). Sudden death reduction in patients with high heart rates may be explained by an antiarrhythmic or antifibrillatory effect. However, an antiarrhythmic effect does not account for all of our findings.. In the present study functional capacity improved, hospital ...
A placebo-controlled study of i.v. amiodarone in patients with supraventricular arrhythmias and 2 to 3-consecutive-beat ventricular arrhythmias, and a pharmacokinetic/pharmacodynamic study evaluating rapid i.v. loading in patients with recurrent, refractory ventricular tachycardia (VT)/ ventricular fibrillation (VF) have shown rapid onset of antiarrhythmic activity well before significant blood levels of desethylamiodarone (DEA) were present; approximately 1500 mg/day of i.v. amiodarone were administered using 2- and 3-stage infusion regimens.
Clinical record. A 73-year-old man presented with recurrent ventricular tachycardia (VT) on a background of severe, non-ischaemic dilated cardiomyopathy (ejection fraction, 20%) and cardiac resynchronisation therapy with an implantable cardioverter defibrillator (ICD). Over the previous 6 months, he had frequent appropriate ICD shocks for VT after unsuccessful antitachycardia pacing. A coronary angiogram was normal. Amiodarone had been successful in reducing VT burden and ICD shocks, but was ceased because of amiodarone-induced thyrotoxicosis. Shortly after discontinuing amiodarone, there was a significant increase in VT burden and appropriate ICD shocks. An endocardial mapping and VT ablation procedure had been performed, but this was unsuccessful and suggested an epicardial source of VT. The patient also underwent subsequent epicardial mapping and VT ablation using a CARTO 3 (Biosense Webster) electroanatomical mapping system, which localised the source of VT to a diffuse area of the basal ...
BACKGROUND: Dronedarone is a new antiarrhythmic drug that is being developed for the treatment of patients with atrial fibrillation. METHODS: We conducted a multicenter trial to evaluate the use of dronedarone in 4628 patients with atrial fibrillation who had additional risk factors for death. Patients were randomly assigned to receive dronedarone, 400 mg twice a day, or placebo. The primary outcome was the first hospitalization due to cardiovascular events or death. Secondary outcomes were death from any cause, death from cardiovascular causes, and hospitalization due to cardiovascular events. RESULTS: The mean follow-up period was 21+/-5 months, with the study drug discontinued prematurely in 696 of the 2301 patients (30.2%) receiving dronedarone and in 716 of the 2327 patients (30.8%) receiving placebo, mostly because of adverse events. The primary outcome occurred in 734 patients (31.9%) in the dronedarone group and in 917 patients (39.4%) in the placebo group, with a hazard ratio for ...

Ten RCTs (1,744 participants) were included.. Amiodarone decreased the incidence of atrial fibrillation or flutter (RR 0.64, 95% CI: 0.55, 0.75, P,0.001). This decrease was similar for both pre-operative and peri-operative treatment, and for oral and intravenous administration.. Amiodarone also decreased the incidence of ventricular tachycardia or fibrillation (RR 0.42, 95% CI: 0.28, 0.63, P,0.001). The results were similar when studies that did not differentiate between sustained and nonsustained ventricular tachycardia or fibrillation were removed (RR 0.34, 95% CI: 0.18, 0.66).. Amiodarone reduced the incidence of stroke (RR 0.39, 95% CI: 0.21, 0.76, P=0.005) and the length of hospital stay (WMD -0.63 days, 95% CI: -1.03, -0.23, P=0.002). No statistically significant differences in mortality were seen between the two treatment groups (RR 0.84, 95% CI: 0.43, 1.65), or in the incidence of MI (RR 0.71, 95% CI: 0.31, 1.62). There was no evidence of statistical heterogeneity or publication bias, ...
Patients randomized to vernakalant received a 10-minute infusion of 3 mg/kg vernakalant in one infusion line, followed by a 15-minute observation period and an additional 10-minute infusion of 2 mg/kg vernakalant if still in AF. To maintain blinding, a 60-minute infusion of placebo (5% dextrose in water) was administered in a second infusion line, followed by a maintenance infusion of placebo for an additional 60 minutes. Patients randomized to amiodarone received a 60-minute infusion of 5 mg/kg amiodarone in one infusion line, followed by a maintenance infusion of 50 mg amiodarone over an additional 60 minutes (equivalent to approximately 15 mg/kg over 24 hours). To maintain blinding, these patients received a 10-minute infusion of placebo (normal saline) in a second infusion line, followed by a 15-minute observation period and a second 10-minute infusion of placebo if still in AF ...

During October 1, 2000 and September 30, 2002, 712 patients were considered for resuscitation and 566 were resuscitated. The initial rhythms were as follows: 32% had VF/VT, 36% had asystole and 32% had pulseless electrical activity (PEA). Of the 180 patients with VF/VT, 75 (42%) received undiluted amiodarone in addition to other resuscitative measures. Of the patients with asystole or PEA, 12 (6%) and 18 (10%), respectively, received amiodarone. The blood pressure levels and the need vasopressors after ROSC and during transportation to the hospital were similar among the patients who received and those who did not receive amiodarone.

Several anti-arrhythmic agents, which are used in treatment of AF, exist. However, the efficacy of these drugs still can be improved. Furthermore, some of them are associated with a wide range of adverse side effects. Therefore, the mechanisms of action of these agents have to be better understood and still can be optimized.. Dronedarone is an anti-arrhythmic agent used in the treatment of AF by maintaining sinus rhythm. It is a derivative of amiodarone and has been developed to reduce the side effects as e.g. thyroid toxicity of its precursor compound.. The aim of this work is to integrate the effects of dronedarone into a model of atrial electrophysiology. In this way, the mechanism of action, i.e. the anti-arrhythmic effects of this agent should be better understood. In previous work, the effects of amiodarone were already integrated into an atrial cell model. Finally, a comparison of both agents and their impact on healthy and electrically remodeled tissue shall be carried out. ...
At the time of the randomization telephone call to the Clinical Trial Center, the investigator reported whether the patient was eligible and agreed to randomization in the First Antiarrhythmic Drug Substudy. Patients randomized to the rhythm control arm of the main AFFIRM study then received a second randomization of the antiarrhythmic drug to be used in this substudy.. The substudy was designed to be three separate comparisons between two drugs: amiodarone versus class I agents, amiodarone versus sotalol, and sotalol versus class I agents. If a patient was eligible for all three drug arms, the randomization was performed among all three drug groups, and the patients data were added to the pool of data in two two-way comparisons. For example, a patient eligible for amiodarone, sotalol, and a class I agent might be randomized to amiodarone. His or her data would be included in the amiodarone arm of both the amiodarone versus class I comparison and in the amiodarone versus sotalol comparison. ...
Objectives Although amiodarone is an effective treatment for severe paediatric arrhythmias, uncertainties about adverse effects such as hypotension, bradycardia and excessive serum drug concentrations persist. Therefore, the aims of this study were to: (a) determine serum concentrations of intravenous (IV) amiodarone following a widely implemented dosing regimen of 5 mg/kg bolus plus a 10 mg/kg/day continuous infusion and (b) generate descriptive data on safety parameters such as hypotension, bradycardia or corrected QT (QTc) prolongation during this regimen.. ...
In their interesting report on the rapid and dramatic reduction in ventricular arrhythmias in patients treated with oral amiodarone, Kim and colleagues [1] correctly point out the possible confounding effects of other antiarrhythmics administered early in the course of amiodarone loading. Despite this caveat, the graphs and P values presented appear impressive. However, several problems in the analysis may render the conclusion erroneous. First, use of analysis of variance (ANOVA) requires an implicit assumption of normally distributed data. No mention was made of data transformation (that is, logarithms), often used to reduce the influence of extreme values and approximate a normally distributed variance. In subsequent analyses, the authors used the Kruskal-Wallis test, a statistic useful for analysis of non-normally distributed data, but the required comparison with the chi-square distribution to test for significance was not cited [2]. In the absence of this and an F statistic for the ...
Discovered in 1961, amiodarone is a cationic amphiphilic molecule which belongs to class III antiarrhythmic drugs and therefore, it is used in the treatment of a wide range of cardiac arrhythmias. Advances in Medicine and Biology. Volume 136 begins by discussing state of the art formulations of amiodarone and outlooks for future dosage forms.. Though amiodarone hydrochloride has often been prescribed for patients with refractory or life-threatening arrhythmias, its clinical use is frequently limited because of a number of side effects such as corneal microdeposits, photosensitivity, pulmonary fibrosis, thyroid and liver dysfunction, and peripheral neuropathy. As such, the authors conduct a study wherein amiodarone hydrochloride dose-dependently induced cell death, lysosomal storage of phospholipids and neutral lipids, and oxidative stress in immortalized Schwann cells..

Atrial fibrillation (AF) is the most common cardiac arrhythmia, and it is associated with increased mortality and morbidity due to increased risk of stroke, poor quality of life and risk of developing heart failure.. Today, catheter ablation has become a standard procedure in the treatment of symptomatic atrial fibrillation, but so far there is no official recommendations regarding the use of antiarrythmic drugs after the procedure. Nevertheless, it is common standard practice to prescribe antiarrhythmic drugs for the first 2-3 months after the intervention to prevent early recurrences. To our knowledge, the effect of antiarrythmic drugs following ablation for atrial fibrillation has only been evaluated in a few recent studies. None of these have evaluated the long term effect of short term antiarrythmic drug treatment. In addition, none of the trials have been conducted placebo-controlled.. In this study patients with paroxysmal or persistent atrial fibrillation will be considered for ...
Amiodarone is the antiarrhythmic drug of choice in treatment of patients suffering from acute tachyarrhythmias and haemodynamic instability due to impaired cardiac function. The intravenous form of amiodarone hydrochloride (IvAm) has individual antiarrhythmic, rate-controlling efficacy, and the dosage is empirical. The main adverse effects are hypotension, severe bradycardia, asystole, acute heart failure, and impaired liver function. Acute liver failure (ALF) is a known but rare complication of IvAm that may be reversible by eliminating the infusion in most cases. The few papers in the literature suppose ALF may be caused by polysorbate 80, the vehicle of IvAm. Oral administration does not to have such an adverse effect, therefore IvAm can be changed to oral form in any cases. ...

It is well known that amiodarone is effective for the treatment of atrial fibrillation. However, effects of amiodarone on the muscarinic acetylcholine receptor-operated K+ current (IK.ACh), which plays an important role in the repolarization of atrial action potential, have not been evaluated. This study was undertaken to determine whether amiodarone inhibits the acetyl-choline-sensitive muscarinic K+ (KACh) channel by use of the patch-clamp technique. In isolated guinea pig atrial cells, IK.ACh was activated by extracellular application of carbachol (1 microM) or adenosine (10 microM) or by the intracellular loading of GTP gamma S (100 microM). Amiodarone inhibited the IK.ACh activated in these three different ways with similar IC50 values around 2 microM, which indicated that amiodarone directly depresses the function of the KACh channel itself and/or GTP-binding proteins. Single KACh channel current was also recorded by use of a pipette solution containing carbachol (1 microM) or atropine (10 ...

A pill-in-the-pocket rhythm-control treatment strategy is acceptable as initial therapy for patients who are quite symptomatic with new-onset paroxysmal AF and no structural heart disease.1 This strategy involves a larger, 1-time dose of a class I antiarrhythmic (propafenone or flecainide). A fast-acting atrioventricular nodal blocking agent such as metoprolol should be used in conjunction to prevent concealed conduction that can progress to ventricular tachycardia or fibrillation. First-time administration requires observation and is usually performed by a cardiologist. Pill-in-the-pocket dosing for flecainide and propafenone can be found in Table 5.1,4,17-19. Dronedarone has received increased attention as a novel agent for the treatment of arrhythmias in the hope of finding a safer alternative to amiodarone therapy. According to data from the ATHENA20 (A Placebo-controlled, Double Blind, Parallel-arm Trial to Assess the Efficacy of Dronedarone 400 mg BID for the Prevention of Cardiovascular ...

Comparing efficacy of ibutilide and amiodarone for cardioversion in atrial fibrillation after coronary artery bypass grafting- A prospective and randomized study - By Mukesh Godara, Pradeep Kumar Goyal, Sonu Kumar Goyal, Dharmendra Carpenter-Indian J Clin Anaesth
General Information. Multaq (Dronedarone) is used if you have had a certain irregular heartbeat in the past but now have a normal heart rhythm. Those are called paroxysmal or persistent atrial fibrillation. This helps you keep a normal heart rhythm. This also lowers your chance of having to go to the hospital for atrial fibrillation.. This should not be used if you have permanent atrial fibrillation because of the increased risk of very serious side effects.. How does Multaq (Dronedarone) work?. Multaq (Dronedarone) works mainly by blocking channels. It is through which charged particles of potassium flow in and out of the heart muscle cells. The increased flow of charged particles produces excessive electrical activity. In which it leads to atrial fibrillation and rapid heart rate. By reducing the flow of potassium through the channels, this drug slows down contractions in the atria. It also prevents fibrillation and lowers the heart rate.. Why use Multaq (Dronedarone)?. Multaq Tablets contains ...

Sensitivity of the skin to a light source can take various forms. People with particular skin types are more sensitive to sunburn. Particular medications make the skin more sensitive to sunlight; these include most of the tetracycline antibiotics, heart drugs amiodarone, and sulfonamides. Particular conditions lead to increased light sensitivity. Patients with systemic lupus erythematosus experience skin symptoms after sunlight exposure; some types of porphyria are aggravated by sunlight. A rare hereditary condition xeroderma pigmentosum (a defect in DNA repair) is thought to increase the risk of UV-light-exposure-related cancer by increasing photosensitivity ...
1. What is the rhythm demonstrated on the EKG?. 2. How would you manage this patient?. ANSWER:. The rhythm is ventricular tachycardia. The patient is stable so he can be managed medically. However, this patient was managed with overdrive pacing. See below.. The rhythm is a wide complex tachycardia at a rate of ~160. In emergency medicine we always assume a wide complex tachycardia is V-tach. That is especially true in a patient with a history of CHF and especially true in a patient with an ICD. (Remember that an ICD is placed because the patient is at high risk for developing V-tach). This rhythm was confirmed to be V-tach.. If the patient was unstable, the treatment would be electrical cardioversion. Since the patient is stable, they can be treated with medications such as amiodarone. However, this patient was already on amiodarone. Other options include lidocaine or procainamide.. However, this patient has an ICD in place which presents other treatment options. In the words of a recent ...

A new series of 2-alkyloxy-pyridine-3-carbonitrile-benzofuran hybrids (4a-x) was synthesized. All the new derivatives were examined via the standard technique for their vasodilation activity. Some of the investigated compounds exhibited a remarkable activity, with compounds 4w, 4e, 4r, 4s, 4f and 4g believed to be the most active hits in this study with IC50 values 0.223, 0.253, 0.254, 0.268, 0.267 and 0.275 mM, respectively, compared with amiodarone hydrochloride, the reference standard used (IC50 = 0.300 mM). CODESSA PRO was employed to obtain a statistically significant 2-Dimensional Quantitative Structure Activity Relationship (2D-QSAR) model describing the bioactivity of the newly synthesized analogs (N = 24, n = 4, R2 = 0.816, R2cvOO = 0.731, R2cvMO = 0.772, F = 21.103, s2 = 6.191 × 10−8).

Our mother, Carol, passed away on November 9, 2018, the day before her 77th birthday, from multi-organ failure, due to a very toxic antiarrhythmic drug that never should have been prescribed to her.. After her passing, my father and I requested her medical records from 2005-2018; which represented the 13 year timeframe her cardiologist kept her on the toxic drug. It was our goal to find out where the breakdown in her medical care occurred. Over the course of four months of reviewing 1,800 pages of documents from the same hospital and clinic system, it became evident to our family what happened. It is now our goal to inform others of her story.. In February 2005, Carol was diagnosed with new on-set paroxysmal atrial fibrillation. The first drug, Sotalol, did not agree with her, so the cardiologist team switched her to Pacerone; which is also referred to as Amiodarone or Cordardone. In 1985, the FDA approved the use of Pacerone (Amiodarone) for life-threatening, recurrent ventricular tachycardia ...

Multaq (dronedarone), a drug used to treat atrial fibrillation, has caused severe liver injury, according to the Food & Drug Administration (FDA). Those Multaq (dronedarone) injuries include two cases of severe liver implant that resulted in liver transplants. In an alert issued today, the FDA said the Warning and Precautions and “Adverse Events†sections of the Multaq (dronedarone) label will be modified to reflect this risk.. Since Multaqs approval in July 2009 through October 2010, around 492,000 dronedarone prescriptions were dispensed and around 147,000 patients filled Multaq (dronedarone) prescriptions at outpatient retail pharmacies in the U.S. Additional usage can occur in the hospital setting. The drug is used to treat abnormal heart rhythm in patients who have had an abnormal heart rhythm (atrial fibrillation or atrial flutter) during the past 6 months.. According ...
The surgery went really well--five hours in a cradle of crushed ice, with no pulse and my chest splayed open. It was afterwards that things got a little dicey.. My heart wouldnt settle down. Rhythm problems afflict about a third of heart surgery patients, so it wasnt at all surprising--to them. To me, though, the next ten days were hellish, because with my heart popping into atrial fibrillation at the least provocation, I couldnt even get out of bed. The first few times it happened, they cardioverted me (which is to say, they put the paddles on me and stopped/started my heart).

... , also known as (-)-3β-(4-iodophenyl)tropane-2β-pyrrolidine carboxamide and RTI-4229-229, is a potent and long-lasting stimulant drug which was developed in the 1990s as part of a large group of related analogues from the phenyltropane family. With the combination of two potent dopamine transporter (DAT) binding motifs attached to the tropane ring, the p-iodophenyl group at the 3β-position and a pyrrolidine carboxamide at 2β, RTI-229 has extremely high selectivity for the dopamine transporter (2600x and 4600x selective over NET and 5-HTT respectively) and is one of the most DAT-selective compounds in the RTI series.[1][2] ...
TCAs were the first medications that had dual mechanism of action. The mechanism of action of tricyclic secondary amine antidepressants is only partly understood. TCAs have dual inhibition effects on norepinephrine reuptake transporters and serotonin reuptake transporters. Increased norepinephrine and serotonin concentrations are obtained by inhibiting both of these transporter proteins. TCAs have substantially more affinity for norepinephrine reuptake proteins than the SSRIs. This is because of a formation of secondary amine TCA metabolites.[24][25] In addition, the TCAs interact with adrenergic receptors. This interaction seems to be critical for increased availability of norepinephrine in or near the synaptic clefts. Actions of imipramine-like tricyclic antidepressants have complex, secondary adaptions to their initial and sustained actions as inhibitors of norepinephrine transport and variable blockade of serotonin transport. Norepinephrine interacts with postsynaptic α and β adrenergic ...
... emerged as a new legal high in the United Kingdom only months after the ban of similar drug mephedrone (which was also a cathinone derivative). Until July 2010 the substance was not controlled by the Misuse of Drugs Act 1971 and was therefore not illegal for someone to possess. The Medicines Act prevented naphyrone from being sold for human consumption, and therefore it was sometimes sold as 'pond cleaner' or as another substance not normally consumed by humans. In response to this emerging trend of new designer drugs, Home Office Minister James Brokenshire said, "action to address the issue of emerging legal highs coming on to the market is a priority for the government."[12][unreliable source?] A study by researchers at Liverpool John Moores University found that only one out of ten products labelled as "NRG-1" actually contained naphyrone when they were subjected to laboratory analysis. Compounds found in products labelled NRG-1 included MDPV, flephedrone, mephedrone, butylone and ...
... is a synthetic form of the isolated major active metabolite of venlafaxine, and is categorized as a serotonin-norepinephrine reuptake inhibitor (SNRI). When most normal metabolizers take venlafaxine, approximately 70% of the dose is metabolized into desvenlafaxine, so the effects of the two drugs are expected to be very similar.[5] It works by blocking the "reuptake" transporters for key neurotransmitters affecting mood, thereby leaving more active neurotransmitters in the synapse. The neurotransmitters affected are serotonin (5-hydroxytryptamine) and norepinephrine (noradrenaline). It is approximately 10 times more potent at inhibiting serotonin uptake than norepinephrine uptake.[6]. ...
... was discovered by scientists at Angelini, who also discovered trazodone.[15] Its development names have included ST-1191 and McN-A-2673-11.[16][1] The INN etoperidone was proposed in 1976 and recommended in 1977.[17][18] The drug was given brand names in Spain (Centren (Esteve) and Depraser (Lepori)) and Italy (Staff (Sigma Tau))[1] and was also given the brand names Axiomin and Etonin,[16] but it is not entirely clear if it was actually marketed; the Pharmaceutical Manufacturing Encyclopedia provides no dates for commercial introduction.[19] According to Micromedex's Index Nominum: International Drug Directory, etoperidone was indeed previously marketed in Spain and Italy.[1] ...

The mechanism of action of armodafinil is unknown. Armodafinil (R-(−)-modafinil) has pharmacological properties almost identical to those of modafinil (a mixture of R-(−)- and (S)-(+)-modafinil). The (R)- and (S)-enantiomers have similar pharmacological action in animals. Armodafinil has wake-promoting actions similar to sympathomimetic agents including amphetamine and methylphenidate, although its pharmacologic profile is not identical to that of the sympathomimetic amines. Armodafinil is an indirect dopamine receptor agonist; it binds in vitro to the dopamine transporter (DAT) and inhibits dopamine reuptake. For modafinil, this activity has been associated in vivo with increased extracellular dopamine levels. In genetically engineered mice lacking the dopamine transporter, modafinil lacked wake-promoting activity, suggesting that this activity was DAT-dependent. However, the wake-promoting effects of modafinil, unlike those of amphetamine, were not antagonized by the dopamine receptor ...
... or WF-23 is a cocaine analogue. It is claimed to be several hundred times more potent than cocaine at being a serotonin-norepinephrine-dopamine reuptake inhibitor.[1] As can be seen on pubmed, these acyl substituted phenyltropanes are highly potent MAT inhibitors and also have a very long half-life, spanning perhaps at least a few days.[2] [3] ...
The dextrorotary (R)-(+)-enantiomer is the most pharmacologically active, although a variety of related derivatives have been studied.[3] Side effects including chest pain (suggestive of possible cardiovascular toxicity) have been seen following recreational use of diphenylprolinol, although it was combined with glaucine in a party pill product, thus making it impossible to say for certain which drug was responsible.[4] ...
In the United States, MDPV is a DEA federally scheduled drug. On October 21, 2011, the DEA issued a temporary one-year ban on MDPV, classifying it as a schedule I substance. Schedule I status is reserved for substances with a high potential for abuse, no currently accepted use for treatment in the United States and a lack of accepted safety standards for use under medical supervision.[28] Before the federal ban was announced, MDPV was already banned in Louisiana and Florida.[29] On March 24, 2011, Kentucky passed bill HB 121, which makes MDPV, as well as three other cathinones, controlled substances in the state. It also makes it a Class A misdemeanor to sell the drug, and a Class B misdemeanor to possess it.[30] MDPV is banned in New Jersey under Pamela's Law. The law is named after Pamela Schmidt, a Rutgers University student who was murdered in March 2011 by an alleged user of MDPV.[31] A toxicology report later found no "bath salts" in his system.[32] On May 5, 2011, Tennessee Governor Bill ...

(CGP-15,210-G) is a selective serotonin reuptake inhibitor (SSRI) which was investigated as an antidepressant in the 1980s but was never marketed.[1][2][3] Ifoxetine selectively blocks the reuptake of serotonin in the brain supposedly without affecting it in the periphery.[3] Supporting this claim, ifoxetine was found to be efficacious in clinical trials and was very well tolerated, producing almost no physical side effects or other complaints of significant concern.[3] ...
... is a norepinephrine-dopamine reuptake inhibitor (NDRI) under development by Jazz Pharmaceuticals for the treatment of excessive sleepiness associated with narcolepsy and sleep apnea. It is derived from phenylalanine and its chemical name is (R)-2-amino-3-phenylpropylcarbamate hydrochloride.[1] The drug was discovered by a subsidiary of SK Group, which licensed rights outside of 11 countries in Asia to Aerial Pharma in 2011.[2] Aerial ran two Phase II trials of the drug in narcolepsy[3] before selling the license to solriamfetol to Jazz in 2014; Jazz paid Aerial $125 million up front and will pay Aerial and SK up to $272 million in milestone payments, and will pay double digit royalties to SK.[2][4] Solriamfetol had also been tested in animal models of depression, but as of 2017 that work had not been advanced to clinical trials.[5] During development it has been called SKL-N05, ADX-N05, ARL-N05, and JZP-110.[6] In March 2018 the FDA accepted SK's and Jazz' NDA for use of ...

... (DOV-220,075) is a serotonin-norepinephrine-dopamine reuptake inhibitor (SNDRI) discovered at American Cyanamid as an analgesic drug candidate, and licensed to DOV Pharmaceutical in 1998 after American Cyanamid was acquired by Wyeth.[1][2][3] In January 2007, Dov licensed the rights to bicifadine to XTL Biopharmaceuticals after bicifadine failed in a Phase III clinical trial for chronic lower back pain.[4][5][6] XTL ran a PhaseIIb clinical trial for pain caused by diabetic neuropathy, which failed in 2008;[7] XTL terminated the agreement in 2010.[8] In 2010 Dov was acquired by Euthymics Bioscience which intended to continue development of other candidates from Dov's portfolio.[9] Bicifadine has a non-opioid, non-NSAID mechanism for the treatment of pain, which should have less abuse potential than opioid drugs and less propensity to cause gastric ulcers than NSAID drugs.[10] While the drug is purported to be a serotonin (SERT) and noradrenaline transporter (NET) inhibitor, it also has ...

... (Merital, Alival) is a norepinephrine-dopamine reuptake inhibitor, i.e. a drug that increases the amount of synaptic norepinephrine and dopamine available to receptors by blocking the dopamine and norepinephrine reuptake transporters.[2] This is a mechanism of action shared by some recreational drugs like cocaine and the medication tametraline (see DRI). Research showed that the (S)-isomer is responsible for activity.[3] The drug was developed in the 1960s by Hoechst AG (now Sanofi-Aventis),[4] who then test marketed it in the United States. It was an effective antidepressant, without sedative effects. Nomifensine did not interact significantly with alcohol and lacked anticholinergic effects. No withdrawal symptoms were seen after 6 months treatment.

(developmental code names SL 81-0385, IXA-001) is an antidepressant which was under clinical development for the treatment of depression in the early 1990s but was never marketed.[1][2] It acts as a potent serotonin reuptake inhibitor (Ki for SERT = 7 nM) and modest 5-HT3 receptor antagonist (Ki = 315 nM).[3][4] It has antiemetic activity, and unlike the selective serotonin reuptake inhibitors (SSRIs), appears to have a negligible incidence of nausea and vomiting.[5] The drug is structurally related to indalpine.[4] Development of litoxetine for depression was apparently ceased in the late 1990s.[6] However, as of March 2017, development of litoxetine has been reinitiated and the drug is now in the phase II stage for the treatment of urinary incontinence.[6] ...
... (brand names Sidnocarb, Sydnocarb) is a drug that is currently being developed for Parkinson's disease.[1] The drug was originally developed in the USSR in the 1970s [2][3] for a variety of indications including asthenia, apathy, adynamia and some clinical aspects of depression and schizophrenia.[4][5] Mesocarb was used for counteracting the sedative effects of benzodiazepine drugs,[6] increasing workload capacity and cardiovascular function,[7] treatment of ADHD and hyperactivity in children,[8][9] as a nootropic,[10] and as a drug to enhance resistance to extremely cold temperatures.[11][12] It is also listed as having antidepressant and anticonvulsant properties. The drug has been found to act as a selective dopamine reuptake inhibitor by blocking the actions of the dopamine transporter (DAT),[13][14] and lacks the dopamine release characteristic of stimulants such as dextroamphetamine.[15][16][17] It was the most selective DAT inhibitor amongst an array of other DAT inhibitors to ...
Randomized, double blind, placebo-controlled trials have confirmed the efficacy of dapoxetine for the treatment of PE.[8] Different dosage has different impacts on different types of PE. Dapoxetine 60 mg significantly improves the mean intravaginal ejaculation latency time (IELT) compared to that of dapoxetine 30 mg in men with lifelong PE, but there is no difference in men with acquired PE.[9] Dapoxetine, given 1-3 hours before sexual episode, prolongs IELT and increases the sense of control and sexual satisfaction in men of 18 to 64 years of age with PE. Since PE is associated with personal distress and interrelationship difficulty, dapoxetine provides help for men with PE to overcome this condition.[10] With no drug approved specifically for treatment for PE in the US and some other countries, other SSRIs such as fluoxetine, paroxetine, sertraline, fluvoxamine, and citalopram have been used off-label to treat PE. Waldinger's meta-analysis shows that the use of these conventional ...
... may be synthesized in a straightforward fashion via the Diels-Alder reaction between cyclopentadiene and β-nitrostyrene (1-nitro-2-phenyl-ethene). The C=C double bond and the nitro-group in the resulting norcamphene derivative are then reduced to give the saturated norcamphane derivative. Finally, the amino-group is ethylated. Although β-nitrostyrene is commercially available, it is also very easily prepared using the Henry Reaction between benzaldehyde and nitromethane.[7] The Diels-Alder reaction of β-nitrostyrene and cyclopentadiene is described in a number of early papers.[8][9] The reduction of the nitroalkene may be carried out sequentially. The alkene's double bond is typically reduced using hydrogen and a transition metal catalyst like Ni or Pt, while the nitro group is reduced to the amine with a metal/acid combination, such as Fe/HCl.[9] The reduction of both functional groups can also be achieved simultaneously by the use of Raney nickel,[9] and this transformation has ...
There has been much debate as to whether reboxetine is more efficacious than placebo in the treatment of depression. According to a 2009 meta-analysis of 12 second-generation antidepressants, reboxetine was no more effective than placebo, and was "significantly less" effective, and less acceptable, than the other drugs in treating the acute-phase of adults with unipolar major depression.[5] The British MHRA said in September 2011 that the study had several limitations, and that "Overall the balance of benefits and risks for reboxetine remains positive in its authorised indication."[6] A UK and Europe-wide review of available efficacy and safety data has confirmed that reboxetine has benefit over placebo in its authorised indication. Efficacy was clearly shown in patients with severe or very severe depression.[6] According to a systematic review and meta-analysis by IQWiG, including unpublished data, published data on reboxetine overestimated the benefit of reboxetine versus placebo by up to 115% ...
A norepinephrine reuptake inhibitor (NRI, NERI) or noradrenaline reuptake inhibitor or adrenergic reuptake inhibitor (ARI), is a type of drug that acts as a reuptake inhibitor for the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline) by blocking the action of the norepinephrine transporter (NET). This in turn leads to increased extracellular concentrations of norepinephrine and epinephrine and therefore can increase adrenergic neurotransmission. NRIs are commonly used in the treatment of conditions like ADHD and narcolepsy due to their psychostimulant effects and in obesity due to their appetite suppressant effects. They are also frequently used as antidepressants for the treatment of major depressive disorder, anxiety and panic disorder. Additionally, many drugs of abuse such as cocaine and methylphenidate possess NRI activity, though it is important to mention that NRIs without combined dopamine reuptake inhibitor (DRI) properties are not significantly rewarding and ...
... , sold under the brand name Azafen or Azaphen, is an antidepressant approved in Russia for the treatment of depression.[1][2][3][4] It was introduced in the late 1960s and is still used today.[5][6] Pipofezine has been shown to act as a potent inhibitor of the reuptake of serotonin.[7][8] In addition to its antidepressant action, pipofezine has sedative effects as well, suggesting antihistamine activity.[4] Other properties such as anticholinergic or antiadrenergic actions are less clear but are likely.[citation needed] ...

  • AIT type I: this type is caused by the load of iodine load released from Amiodarone leading to increased thyroid hormone synthesis. (
  • Although amiodarone is regarded as a highly effective anti-arrhythmic agent, its use may lead to alterations in thyroid gland function and/or thyroid hormone metabolism, partly because of its rich iodine content. (
  • It prevails in areas with high dietary iodine intake, and it is readily managed by discontinuation of amiodarone or thyroid hormone replacement. (
  • 1-3 The purposes of this review are to summarise expected and abnormal changes in thyroid function and thyroid hormone metabolism in patients taking amiodarone, and to suggest guidelines for the diagnosis and management of amiodarone-induced thyroid dysfunction. (

  • These adverse events may pose a serious threat to the patient, requiring the discontinuation of amiodarone. (
  • However, it has been argued that the increased risk of TdP might be due to women having higher amiodarone concentrations as standard doses are usually used and women in general have a lower body weight than men [7]. (
  • Therefore, intraoperative prophylactic treatment with amiodarone at the tested doses does not appear to be justified. (
  • When the risk associated with cumulative doses was further stratified into tertiles, patients in the intermediate and highest levels of amiodarone exposure had adjusted HRs of 1.70 (95% CI: 1.02-2.84, P =0.042) and 1.98 (95% CI: 1.22-3.22, P =0.006), respectively. (

  • Protective effects of neferine on amiodarone-induced pulmonary fibrosis in mice. (
  • The effects of neferine, a bisbenzylisoquinline alkaloid extracted from the Chinese traditional medicine seed embryo of Nelumbo nucifera Gaertn, on amiodarone-induced pulmonary fibrosis in mice were evaluated. (
  • Adult Kunming mice were induced to develop pulmonary fibrosis through intratracheal instillation of amiodarone (6.25 mg/kg) on the 1st, 3rd and 5th day. (
  • In conclusion, these results indicated that neferine possessed a significant inhibitory effect on amiodarone-induced pulmonary fibrosis, probably due to its properties of anti-inflammation, SP-D inhibition and restoring increased CD4+CD25+ Tregs which may modulate Th1/Th2 imbalance by suppressing Th2 response (from Th2 polarity toward a Th1 dominant response). (
  • Pulmonary fibrosis was diagnosed in four patients (1.1%) treated with amiodarone and in three patients (0.8%) receiving placebo. (

  • We will continue to monitor Harvoni and Sovaldi for risks of serious symptomatic bradycardia and further investigate the reason why the use of amiodarone with these hepatitis C drugs led to the heart-related events. (
  • Unlike class I and III antiarrhythmic drugs, amiodarone does not carry the risk of increased mortality caused by a proarrhythmic effect ( 3,4 ), including in patients with heart failure ( 5 ). (
  • As simvastatin and amiodarone are metabolised by the same isoenzyme, in the present case, the concomitant use of these drugs may have resulted in competition, resulting in excess of free plasma statin and thereby causing myotoxicity. (

  • On the other hand, analysis of the free sterols in promastigotes incubated with amiodarone showed that this drug also affected the biosynthesis of 5-dehydroepisterol, which results in squalene accumulation, thus suggesting that amiodarone inhibits the squalene epoxidase activity of the parasite. (
  • The U.S. Food and Drug Administration (FDA) is warning that serious slowing of the heart rate can occur when the antiarrhythmic drug amiodarone is taken together with either the hepatitis C drug Harvoni (ledipasvir/sofosbuvir) or with Sovaldi (sofosbuvir) taken in combination with another direct acting antiviral for the treatment of hepatitis C infection. (
