Drugs that mimic the effects of stimulating postganglionic adrenergic sympathetic nerves. Included here are drugs that directly stimulate adrenergic receptors and drugs that act indirectly by provoking the release of adrenergic transmitters.
An indirect sympathomimetic. Tyramine does not directly activate adrenergic receptors, but it can serve as a substrate for adrenergic uptake systems and monoamine oxidase so it prolongs the actions of adrenergic transmitters. It also provokes transmitter release from adrenergic terminals. Tyramine may be a neurotransmitter in some invertebrate nervous systems.
A phenethylamine found in EPHEDRA SINICA. PSEUDOEPHEDRINE is an isomer. It is an alpha- and beta-adrenergic agonist that may also enhance release of norepinephrine. It has been used for asthma, heart failure, rhinitis, and urinary incontinence, and for its central nervous system stimulatory effects in the treatment of narcolepsy and depression. It has become less extensively used with the advent of more selective agonists.
Drugs that inhibit the actions of the sympathetic nervous system by any mechanism. The most common of these are the ADRENERGIC ANTAGONISTS and drugs that deplete norepinephrine or reduce the release of transmitters from adrenergic postganglionic terminals (see ADRENERGIC AGENTS). Drugs that act in the central nervous system to reduce sympathetic activity (e.g., centrally acting alpha-2 adrenergic agonists, see ADRENERGIC ALPHA-AGONISTS) are included here.

A cardioselective beta-1-adrenergic antagonist with no partial agonist activity.
Cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. The two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands.

An enzyme that catalyzes the oxidative deamination of naturally occurring monoamines. It is a flavin-containing enzyme that is localized in mitochondrial membranes, whether in nerve terminals, the liver, or other organs. Monoamine oxidase is important in regulating the metabolic degradation of catecholamines and serotonin in neural or target tissues. Hepatic monoamine oxidase has a crucial defensive role in inactivating circulating monoamines or those, such as tyramine, that originate in the gut and are absorbed into the portal circulation.

Kinetic analysis of drug-receptor interactions of long-acting beta2 sympathomimetics in isolated receptor membranes: evidence against prolonged effects of salmeterol and formoterol on receptor-coupled adenylyl cyclase. (1/590)

The long-acting beta2 sympathomimetics salmeterol and formoterol have been presumed to exert their prolonged action either by binding to an accessory binding site ("exo-site") near the beta2 adrenoceptor or by their high affinity for beta2 adrenoceptors and correspondingly slow dissociation. Whereas most studies with salmeterol had been done in intact tissues, which have slow diffusion and compartmentation of drugs in lipophilic phases, that restrict drug access to the receptor biophase, we used purified receptor membranes from rat lung and disaggregated calf tracheal myocytes as model systems. Binding experiments were designed to measure the slow dissociation of agonists by means of delayed association of (-)-[125I]iodopindolol. Rat lung membranes were pretreated with high concentrations of agonists (salmeterol, formoterol, isoprenaline) before dissociation was induced by 50-fold dilution. Half-times of association of (-)-[125I]iodopindolol remained unchanged compared with untreated controls, indicating that dissociation of agonists occurred in less than 2 min. Adenylyl cyclase experiments were designed to determine the on and off kinetics of agonists to beta2 adrenoceptors by measuring the rate of receptor-induced cyclic AMP (cAMP) formation. Experiments were performed in tracheal membranes characterized by high Vmax values of cAMP formation. Adenylyl cyclase activation occurred simultaneously with the addition of the agonist, continued linearly with time for 60 min, and ceased immediately after the antagonist was added. Similarly, when receptor membranes were preincubated in a small volume with high salmeterol concentrations, there was a linear increase in cAMP formation, which was immediately interrupted by a 100-fold dilution of the reaction mixture. This militates against the exo-site hypothesis. On the other hand, dissociation by dilution was much less when membranes were preincubated with a large volume of salmeterol at the same concentration, indicating that physicochemical effects, and not exo-site binding, underlie its prolonged mode of action.  (+info)

Long-term effects of prior heat shock on neuronal potassium currents recorded in a novel insect ganglion slice preparation. (2/590)

Brief exposure to high temperatures (heat shock) induces long-lasting adaptive changes in the molecular biology of protein interactions and behavior of poikilotherms. However, little is known about heat shock effects on neuronal properties. To investigate how heat shock affects neuronal properties we developed an insect ganglion slice from locusts. The functional integrity of neuronal circuits in slices was demonstrated by recordings from rhythmically active respiratory neurons and by the ability to induce rhythmic population activity with octopamine. Under these "functional" in vitro conditions we recorded outward potassium currents from neurons of the ventral midline of the A1 metathoracic neuromere. In control neurons, voltage steps to 40 mV from a holding potential of -60 mV evoked in control neurons potassium currents with a peak current of 10.0 +/- 2.5 nA and a large steady state current of 8.5 +/- 2.6 nA, which was still activated from a holding potential of -40 mV. After heat shock most of the outward current inactivated rapidly (peak amplitude: 8.4 +/- 2.4 nA; steady state: 3.6 +/- 2.0 nA). This current was inactivated at a holding potential of -40 mV. The response to temperature changes was also significantly different. After changing the temperature from 38 to 42 degrees C the amplitude of the peak and steady-state current was significantly lower in neurons obtained from heat-shocked animals than those obtained from controls. Our study indicates that not only heat shock can alter neuronal properties, but also that it is possible to investigate ion currents in insect ganglion slices.  (+info)

Effect of the cannabinoid receptor agonist WIN55212-2 on sympathetic cardiovascular regulation. (3/590)

1. The aim of the present study was to analyse the cardiovascular actions of the synthetic CB1/CB2 cannabinoid receptor agonist WIN55212-2, and specifically to determine its sites of action on sympathetic cardiovascular regulation. 2. Pithed rabbits in which the sympathetic outflow was continuously stimulated electrically or which received a pressor infusion of noradrenaline were used to study peripheral prejunctional and direct vascular effects, respectively. For studying effects on brain stem cardiovascular regulatory centres, drugs were administered into the cisterna cerebellomedullaris in conscious rabbits. Overall cardiovascular effects of the cannabinoid were studied in conscious rabbits with intravenous drug administration. 3. In pithed rabbits in which the sympathetic outflow was continuously electrically stimulated, intravenous injection of WIN55212-2 (5, 50 and 500 microg kg(-1)) markedly reduced blood pressure, the spillover of noradrenaline into plasma and the plasma noradrenaline concentration, and these effects were antagonized by the CB1 cannabinoid receptor-selective antagonist SR141716A. The hypotensive and the sympathoinhibitory effect of WIN55212-2 was shared by CP55940, another mixed CB1/CB2 cannabinoid receptor agonist, but not by WIN55212-3, the enantiomer of WIN55212-2, which lacks affinity for cannabinoid binding sites. WIN55212-2 had no effect on vascular tone established by infusion of noradrenaline in pithed rabbits. 4. Intracisternal application of WIN55212-2 (0.1, 1 and 10 microg kg(-1)) in conscious rabbits increased blood pressure and the plasma noradrenaline concentration and elicited bradycardia; this latter effect was antagonized by atropine. 5. In conscious animals, intravenous injection of WIN55212-2 (5 and 50 microg kg(-1)) caused bradycardia, slight hypotension, no change in the plasma noradrenaline concentration, and an increase in renal sympathetic nerve firing. The highest dose of WIN55212-2 (500 microg kg(-1)) elicited hypotension and tachycardia, and sympathetic nerve activity and the plasma noradrenaline concentration declined. 6. The results obtained in pithed rabbits indicate that activation of CB1 cannabinoid receptors leads to marked peripheral prejunctional inhibition of noradrenaline release from postganglionic sympathetic axons. Intracisternal application of WIN55212-2 uncovered two effects on brain stem cardiovascular centres: sympathoexcitation and activation of cardiac vagal fibres. The highest dose of systemically administered WIN55212-2 produced central sympathoinhibition; the primary site of this action is not known.  (+info)

Induction of neurally mediated syncope with adenosine. (4/590)

BACKGROUND: Tilt testing is used to establish the diagnosis of neurally mediated syncope. However, applicability of the tilt test is limited by test sensitivity and length of time required to perform the test. We hypothesized that adenosine could facilitate the induction of neurally mediated syncope through its sympathomimetic effects and therefore could be used as an alternative to routine tilt testing. METHODS AND RESULTS: In protocol 1, the yield of adenosine tilt testing (12 mg while upright, followed by 60 degrees tilt for 5 minutes) and a 15-minute isoproterenol tilt test were compared in 84 patients with a negative 30-minute drug-free tilt test. In protocol 2, 100 patients underwent an initial adenosine tilt test followed by our routine tilt test (30-minute drug-free tilt followed by a 15-minute isoproterenol tilt). Six additional control patients underwent microneurography of the peroneal nerve to compare the sympathomimetic effects during bolus administration of adenosine and continuous infusion of isoproterenol. In protocol 1, the yields of adenosine (8 of 84, 10%) and isoproterenol (7 of 84, 8%) tilt testing were comparable (P=NS). In protocol 2, the yields of adenosine (19 of 100, 19%) and routine (22 of 100, 22%) tilt testing were also comparable (P=NS). Although the yield of adenosine tilt testing was comparable in both protocols, patients with a negative adenosine tilt test but a positive routine tilt test usually required isoproterenol to elicit the positive response. Microneurography confirmed discordant sympathetic activation after adenosine and isoproterenol administration. CONCLUSIONS: Adenosine is effective for the induction of neurally mediated syncope, with a diagnostic yield comparable to routine tilt testing. However, the discordant results obtained with adenosine and the isoproterenol phase of routine tilt testing suggest that adenosine and isoproterenol tilt testing may have complementary roles in eliciting a positive response. Therefore, a tilt protocol that uses an initial adenosine tilt followed, if necessary, by an isoproterenol tilt would be expected to increase the overall yield and reduce the duration of tilt testing.  (+info)

Aldosterone, not estradiol, is the physiological agonist for rapid increases in cAMP in vascular smooth muscle cells. (5/590)

BACKGROUND: Steroid-induced gene regulation in the endocrine tissues and vascular wall is achieved through the interaction of specific receptor proteins and promoters of target genes. In addition to these delayed steroid actions, rapid effects of steroids have been reported in various tissues that were clearly incompatible with the classic theory of genomic steroid action. METHODS AND RESULTS: Because high doses of 17beta-estradiol have been shown to modulate intracellular cAMP levels in vascular smooth muscle cells, steroid-induced stimulation of adenylate cyclase stimulation and phosphorylation of cAMP response element binding protein was investigated in porcine coronary artery vascular smooth muscle cells. Aldosterone induces a approximately 1.5- to 2.5-fold increase in intracellular cAMP levels (EC50 approximately 0.01 to 0.1 nmol/L) within 1 minute, whereas 17beta-estradiol and hydrocortisone act only at supraphysiological concentrations (10 micromol/L). Aldosterone-induced changes in intracellular cAMP are calcium dependent; they are not blocked by inhibitors of mineralocorticoid receptors, transcription, or protein synthesis. In addition, aldosterone induces a time-dependent phosphorylation of cAMP response element binding protein with potential transcriptional importance. CONCLUSIONS: A nongenomic modulation of vascular smooth muscle cells by aldosterone is consistent with the data that aldosterone, not estrogen, is the physiological stimulus for cAMP.  (+info)

Utility of a single-stage isoproterenol tilt table test in adults: a randomized comparison with passive head-up tilt. (6/590)

OBJECTIVES: This study was conducted to develop a time-efficient tilt table test. BACKGROUND: Current protocols of tilt table testing are quite time-consuming. This study was designed to assess the diagnostic value, tolerance and procedural time of a single-stage isoproterenol tilt table protocol. METHODS: A single-stage isoproterenol tilt table test was compared with the passive tilt table test. The study was prospectively designed in a randomized and crossover fashion. RESULTS: The study population consisted of 111 patients with a history of syncope (mean age 55 +/- 20 years). Of the total, 62 patients (56%; 95% confidence interval, 46% to 65%) had a positive vasovagal response during isoproterenol tilt table testing and 35 (32%; 23% to 41%) during passive tilt table testing (p = 0.002). The mean procedural times of the study population were 11.7 +/- 3.6 min and 36.9 +/- 13.3 min for isoproterenol and passive tilt table testing, respectively (p < 0.001). All patients tolerated single-stage isoproterenol testing. In the 23 control subjects (mean age 34 +/- 11 years), the apparent specificities were 91% (72% to 99%) and 83% (61% to 99%) for passive and single-stage tilt table testing, respectively. CONCLUSIONS: The single-stage isoproterenol tilt table test was more effective in inducing a positive vasovagal response in an adult population than the standard passive tilt table test, and it significantly reduced the procedural time. The increase in positive yield was associated with a moderate decrease in apparent specificity. These observations support the conclusion that single-stage tilt table testing could be a reasonable diagnostic option in patients undergoing syncope evaluation.  (+info)

Recovery of locomotion after ventral and ventrolateral spinal lesions in the cat. II. Effects of noradrenergic and serotoninergic drugs. (7/590)

The effects of serotoninergic and noradrenergic drugs (applied intrathecally) on treadmill locomotion were evaluated in two adult cats subjected to a ventral and ventrolateral spinal lesion (T13). Despite the extensive spinal lesion, severely damaging important descending pathways such as the reticulo- and vestibulospinal tracts, both cats recovered quadrupedal voluntary locomotion. As detailed in a previous paper, the locomotor recovery occurred in three stages defined as early period, when the animal could not walk with its hindlimbs, recovery period, when progressive improvement occurred, and plateau period, when a more stable locomotor performance was observed. At this latter stage, the cats suffered from postural and locomotor deficits, such as poor lateral stability, irregular stepping of the hindlimbs, and inconsistent homolateral fore- and hindlimb coupling. The present study aimed at evaluating the potential of serotoninergic and/or noradrenergic drugs to improve the locomotor abilities in the early and late stages. Both cats were implanted chronically with an intrathecal cannula and electromyographic (EMG) electrodes, which allowed determination, under similar recording conditions, of the locomotor performance pre- and postlesion and comparisons of the effects of different drugs. EMG and kinematic analyses showed that norepinephrine (NE) injected in early and plateau periods improved the regularity of the hindlimb stepping and stabilized the interlimb coupling, permitting to maintain constant locomotion for longer periods of time. Methoxamine, the alpha1-agonist (tested only at the plateau period), had similar effects. In contrast, the alpha2-agonist, clonidine, deteriorated walking. Serotoninergic drugs, such as the neurotransmitter itself, serotonin (5HT), the precursor 5-hydroxytryptophan (5HTP), and the agonist quipazine improved the locomotion by increasing regularity of the hindlimb stepping and by increasing the step cycle duration. In contrast, the 5HT1A agonist 8-hydroxy-dipropylaminotetralin (DPAT) caused foot drag in one of the cats, resulting in frequent stumbling. Injection of combination of methoxamine and quipazine resulted in maintained, regular stepping with smooth movements and good lateral stability. Our results show that the effects of drugs can be integrated to the residual voluntary locomotion and improve some of its postural aspects. However, this work shows clearly that the effects of drugs (such as clonidine) may depend on whether or not the spinal lesion is complete. In a clinical context, this may suggest that different classes of drugs could be used in patients with different types of spinal cord injuries. Possible mechanisms underlying the effect of noradrenergic and serotoninergic drugs on the locomotion after partial spinal lesions are discussed.  (+info)

Topical therapies for glaucoma: what family physicians need to know. (8/590)

Medication classes historically used in the management of glaucoma include beta blockers, miotics, sympathomimetics and carbonic anhydrase inhibitors. Because topically applied medications are more site specific, they are preferred in the treatment of glaucoma. Compared with oral medications, topical agents are associated with a decreased incidence of systemic side effects. With topical administration, conjunctival and localized skin allergic reactions are relatively common, whereas severe reactions, including death, are rare. Recently introduced topical agents for glaucoma therapy include dorzolamide and brinzolamide, the first topical carbonic anhydrase inhibitors; brimonidine and apraclonidine, more ocular-specific alpha agonists; and latanoprost, a prostaglandin analog, which is a new class of glaucoma medication. Latanoprost has the unique side effect of increasing iris pigmentation. Like their predecessors, the newer agents lower intraocular pressure by a statistically significant degree. Preservation of visual field, the more substantial patient-oriented end point, continues to be studied.  (+info)

AU - Webster, Keith A.. AU - Ohlstein, Eliot H.. AU - Bishopric, Nanette H.. PY - 2002/5/21. Y1 - 2002/5/21. N2 - Background - Most clinical studies have shown that β-adrenergic receptor antagonists improve long-term survival in heart failure patients. Bucindolol, a nonselective β-receptor blocker, however, failed to reduce heart failure mortality in a recent large clinical trial. The reasons for this failure are not known. Bucindolol has partial agonist properties in rat myocardium, but whether it has agonist activity in human heart is controversial. To address this, we measured the ability of bucindolol to increase cAMP accumulation in human myocardium. Methods and Results - Myocardial strips (≈ 1 mm3) obtained from rat and nonfailing human hearts were confirmed to be viable for ≥48 hours in ...

TY - JOUR. T1 - Cerebrovascular complications of alcohol and sympathomimetic drug abuse. AU - Bruno, Askiel. PY - 2003/1/1. Y1 - 2003/1/1. N2 - Alcohol abuse has been linked to intracranial hemorrhage, both intracerebral and subarachnoid. Some studies have found a dose-response relationship, so that increasing levels of abuse are associated with greater risk of hemorrhage. However, alcohol abuse has not been clearly linked to cerebral infarction, and some studies find that mild-to-moderate drinking appears to be associated with a decreased risk of cerebral infarction. Intravenous administration of drugs of abuse predisposes to endocarditis, which may lead to embolic stroke. Associations have been reported between various sympathomimetic drugs and cerebral infarction. A possible mechanism for cerebral infarction is focal arterial vasoconstriction and occasionally cerebral vasculitis. Associations have also been reported between various sympathomimetic drugs and intracranial hemorrhage. A likely ...

The use of sympathomimetics was positively associated with a 10% higher sperm motility (beta 10.265; 95% confidence interval [CI] 3.258-17.272) after adjustment for smoking, alcohol use, age, geographic background, BMI, folic acid supplement use, the four astronomical seasons and asthma/bronchitis. Subgroup analysis between men with total motile sperm count (TMSC) < or ≥10 million showed that this association remained (P ≤ 0.001) after adjustment for these confounders. After adjustment for confounders the sperm concentration was also positively associated with the use of sympathomimetics, but only in men with TMSC ≥10 million (beta 0.300; 95% CI 0.032-0.568 ...

Sympathomimetic amines are drugs that stimulate the sympathetic nervous system and induce various responses. These types of drugs can be classified as catecholamines or noncatecholamines....
Epinephrine is a hormone produced by the adrenal glands (located above the kidneys within the abdomen). The adrenal glands naturally release a very small amount of this substance that may bind to specialized ß2 (beta-2) receptors in the lungs. These receptors, in turn, are responsible for bronchodilation (relaxing of bronchial tube constriction). In addition, epinephrine also can stimulate the heart to beat faster and elevate the blood pressure. If you are asthmatic, you may have a deficiency in the biochemistry of your ß2 receptors. Therefore the amount of natural epinephrine that you produce may be insufficient to promote adequate stimulation and bronchodilation. Sympathomimetic medications stimulate biochemical changes in the airway, which leads to quick relief of asthmatic symptoms as the airway opens. They are reliever medications.. Sympathomimetic medications include:. ...

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 ...

Oxprenolol (brand names Trasacor, Trasicor, Coretal, Laracor, Slow-Pren, Captol, Corbeton, Slow-Trasicor, Tevacor, Trasitensin, Trasidex) is a non-selective beta blocker with some intrinsic sympathomimetic activity. It is used for the treatment of angina pectoris, abnormal heart rhythms and high blood pressure. Oxprenolol is a lipophilic beta blocker which passes the blood-brain barrier more easily than water-soluble beta blockers. As such, it is associated with a higher incidence of CNS-related side effects than hydrophilic ligands such as atenolol, sotalol and nadolol. Oxprenolol is a potent beta blocker and should not be administered to asthmatics under any circumstances due to their low beta levels as a result of depletion due to other asthma medication, and because it can cause irreversible, often fatal, airway failure and inflammation. Oxprenolol is a beta blocker. In addition, it has been found to act as an antagonist of the serotonin 5-HT1A and 5-HT1B receptors with respective Ki values ...

The sympathomimetic catecholamines produce effects that depend upon their relative specificity for alpha, beta 1 and beta 2 receptors.. Adrenaline: With both alpha and beta effects this will produce an augmentation in heart rate, systolic blood pressure and cardiac output. In addition it produces relaxation of bronchial smooth muscle. However these effects occur at the expense of increased myocardial oxygen demand and reduced perfusion of skin, kidneys and other organs. It is used for its inotropic effect at doses of 0.01-0.02 μg/kg/min titrated according to response.. Noradrenaline: This has predominantly alpha effects but also slight beta effects on the heart. It produces an increase in both systolic and diastolic pressure but its principle effect is to increase peripheral resistance. This is disadvantageous when peripheral resistance is normal as it then produces an increase in resistance and raises cardiac afterload. However it is useful when the peripheral resistance is inappropriately ...

The action of nine sympathomimetic amines on contractility and on phosphorylase a and total phosphorylase activity of the isolated perfused rat heart has been studied. The following observations have been made. 1) The sympathomimetic amines with a positive inotropic action on the heart caused an increase in phosphorylase a activity of the myocarclium, hut did not change total phosphorylase activity. 2) Sympathomimetic amines with no action on the contractility of the heart had no effect on phosphorylase a activity. 3) With each drug studied there was a correlation at all drug concentrations between the increase in systolic isometric tension and the increase of phosphorylase a activity. 4) Linear log dose-response curves were obtained in studies of the action of epinephrine, norepinephrine and isoproterenol on phosphorylase a activity. 5) The structure-activity relationship of the nine drugs was the same for their ability to increase the force of contraction and for their action on phosphorylase. ...
Pindolol is a non-selective beta-adrenergic antagonist (beta-blocker) which possesses intrinsic sympathomimetic activity (ISA) in therapeutic dosage ranges but does not possess quinidine-like membrane stabilizing activity. Pindolol impairs AV node conduction and decreases sinus rate and may also increase plasma triglycerides and decrease HDL-cholesterol levels. Pindolol is nonpolar and hydrophobic, with low to moderate lipid solubility. Pindolol has little to no intrinsic sympathomimetic activity and, unlike some other beta-adrenergic blocking agents, pindolol has little direct myocardial depressant activity and does not have an anesthetic-like membrane-stabilizing action ...
Several sympathomimetic agents have been associated with ischemic and hemorrhagic stroke. Ephedrine, a sympathomimetic drug that has a high potential for abuse and can be readily obtained without a prescription in unrestricted quantities, has rarely been associated with stroke. We report ephedrine-related stroke in three patients. One patient developed a thalamic infarct after ingesting known quantities of ephedrine as street-purchased speed for weight loss. Two patients had fatal intracranial hemorrhages after ingesting unknown quantities of ephedrine; one of them had a history of drug abuse, and one lacked a history of ephedrine use or drug abuse. Ephedrine appears to predispose to both ischemic and hemorrhagic stroke. The mechanisms responsible for the different cerebrovascular complications remain to be proven. Restriction of ephedrine availability should be considered.. ...
Phenmetrazine is a sympathomimetic drug used primarily as an appetite depressant. Its actions and mechanisms are similar to dextroamphetamine. Amphetamines are non-catecholamine sympathomimetic amines with CNS stimulant activity. Phenmetrazine was originally sold under the tradename Preludin as an anorectic. It has since been removed from the market. It is by some considered to have a greater potential for addiction than the amphetamines, and has been abused in many countries, for example Sweden ...
The local hemodynamic effect of pindolol, a nonselective beta-blocker with intrinsic sympathomimetic activity, was investigated in 17 healthy volunteers. Changes in forearm blood flow (FBF) in response to infusion of drugs into the brachial artery were measured by plethysmography. Pindolol increased FBF dose dependently to a maximal value of 62 +/- 8% (mean +/- SEM, p less than 0.001) without inducing changes in heart rate or blood pressure. For a single dose of pindolol the maximal effect on FBF was seen after approximately 4 minutes of infusion, and this effect persisted for at least 12 minutes after the infusion. The pindolol-induced increase in FBF was reduced by concomitant infusion of propranolol (p less than 0.001). Intra-arterial infusion of practolol did not influence FBF. No significant influence of pindolol was found on the vasoconstriction induced by the alpha 1-adrenergic receptor agonist methoxamine, the alpha 2-adrenergic receptor agonist BHT-933, or angiotensin II. Measurement of ...
Bisoprolol is a competitive, cardioselective β1-adrenergic antagonist. Activation of β1-receptors (located mainly in the heart) by epinephrine increases heart rate and the blood pressure causing the heart to consume more oxygen. β1-adrenergic blocking agents such as bisopolol lower the heart rate and blood pressure and may be used to reduce workload on the heart and hence oxygen demands. They are routinely prescribed in patients with ischemic heart disease. In addition, β1-selective blockers prevent the release of renin, a hormone produced by the kidneys causes constriction of blood vessels. Bisoprolol is lipophilic and exhibits no intrinsic sympathomimetic activity (ISA) or membrane-stabilizing activity ...
Bisoprolol fumarate is a beta1-selective (cardioselective) adrenoceptor blocking agent without significant membrane stabilizing activity or intrinsic sympathomimetic activity in its therapeutic dosage range. Cardioselectivity is not absolute, however, and at higher doses (≥20 mg) bisoprolol fumarate also inhibits beta2-adrenoceptors, chiefly located in the bronchial and vascular musculature; to retain selectivity it is therefore important to use the lowest effective dose. The most prominent effect of bisoprolol fumarate is the negative chronotropic effect, resulting in a reduction in resting and exercise heart rate. There is a fall in resting and exercise cardiac output with little observed change in stroke volume, and only a small increase in right atrial pressure, or pulmonary capillary wedge pressure at rest or during exercise. Findings in short-term clinical hemodynamics studies with bisoprolol fumarate are similar to those observed with other beta-blocking agents. In normal volunteers, ...
The presence of left ventricular hypertrophy (LVH) as a treatable entity is of particular importance in patients with primary hypertension. Because LVH is associated with a strong risk of adverse clinical events (eg, heart failure, ischemic events, and cardiovascular death) and because evidence from retrospective studies suggests that regression of LVH, along with a decrease in blood pressure, may help modify these outcomes, the use of antihypertensive agents that have been shown to promote regression of LVH has been recommended. These include diuretics, beta-blockers (except those with intrinsic sympathomimetic activity ), angiotensin-converting enzyme (ACE) inhibitors, calcium channel blockers, peripheral alpha(1)-blockers, and central alpha(2)-stimulators. Agents to be avoided include direct arterial vasodilators (eg, hydralazine and minoxidil), which have strong sympathetic stimulating properties and tend to maintain LVH despite lowering blood pressure. The use of ACE inhibitors is increasing.
Acebutolol is a medication used to treat hypertension and cardiac arrhythmias. Acebutolol is a cardio selective beta blocker with intrinsic sympathomimetic activity, and so is infinitely more suitable than non-cardioselective beta blockers for patients with chronic obstructive pulmonary disease or asthma due to the fact that doses lower than 800mg daily have only 10-30% of…

Clenbuterol belongs to a class of drugs known as sympathomimetics. These drugs affect the sympathetic nervous system in numerous ways. It is specifically a selective beta-2 sympathomimetic, stimulating the beta-2 receptors, which creates a thermogenic effect, directly stimulating fat cells and accelerating the breakdown of triglycerides to form free fatty acids. Animal studies have also shown it to be quite anti-catabolic and/or anabolic which obviously leads to its attractiveness amongst bodybuilders - particularly during the pre-contest phase. However, it has to be said that these studies have been restricted to animals and there is little real evidence of Clenbuterol having muscle building/sparingproperties in humans. This does little to tarnish its reputation as a great adjunct anabolic - used both off-season and pre-contest.. ...

Pimobendan. Newer Heart Failure Therapy. Pimobendan. Most positive inotropes increase the cytosolic concentration of calcium to increase the availability of calcium, but pimobendan has the novel action of increasing the sensitivity of the contractile proteins to calcium, an effect thought to be mediated by altering the binding of calcium to the troponin complex, and the increase in the extent of sarcomere shortening is achieved without the same energy consumption associated with sympathomimetic drugs. Pimobendan has both calcium sensitizing effects and some phosphodiesterase inhibitory effects. The calcium sensitizing effects appear to predominate in failing myocardium, because of down-regulation of the adrenergic signaling pathway. The phosphodiesterase inhibition also results in vasodilation. Phosphodiesterases are involved in the breakdown of cAMP in vascular smooth muscle, and inhibitors of these phosphodiesterases will cause venodilation and arteriodilation. There has been no significant ...
Absorption isnt so easy. I can think of some interesting interactions. For example if taking an MAO inhibitor (e.g., clorgyline) then the ingestion of sympathomimetic amines (e.g. amphetamine or even tyramine from cheese) will increase their [amines] apparent absorption as there is no longer functional MAO in the gut epithelium to degrade it. This can lead to the cheese effect which results in severe hypertension, flushing and can be fatal ...

Tramazoline hydrochloride belongs to a group of medicines called sympathomimetics, which work by stimulating alpha-receptors in certain areas of the body. When applied as a nasal spray, tramazoline acts on the alpha receptors in the walls of blood vessels in the nose. This causes them to narrow and results in less blood travelling through the vessels in the nose. This in turn, decreases the amount of fluid pushed out into the nasal lining, and so reducing mucus secretionDexamethasone belongs to a group of medicines known as corticosteroids, used for reducing inflammation. Inflammation occurs as a result of allergy or irritation and is caused by the release of substances that are important in the immune system. These substances cause blood vessels to widen, resulting in the affected area becoming red, swollen, itchy and painful. Dexamethasone when applied as a nasal spray works by acting within cells to decrease the release of these substances in the nose, thereby reducing swelling, redness and itch

Acres Treated is the acreage of the crop actually treated with the pesticide. Gross Pounds applied divided by Acres Treated is the application rate of the pesticide. The difference between Acres Planted and Acres Treated is best explained through an example:If a farmer has a 100-acre field and sprays 50 acres, then the Acres Planted will be 100 and the Acres Treated will be 50.
