One of the two major pharmacological subdivisions of adrenergic receptors that were originally defined by the relative potencies of various adrenergic compounds. The alpha receptors were initially described as excitatory receptors that post-junctionally stimulate SMOOTH MUSCLE contraction. However, further analysis has revealed a more complex picture involving several alpha receptor subtypes and their involvement in feedback regulation.

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. Adrenergic receptors may also be classified according to the subtypes of G-proteins with which they bind; this scheme does not respect the alpha-beta distinction.

Neural modulation of cephalexin intestinal absorption through the di- and tripeptide brush border transporter of rat jejunum in vivo. (1/784)

Intestinal absorption of beta-lactamine antibiotics (e.g., cefixime and cephalexin) has been shown to proceed through the dipeptide carrier system. In a previous study, nifedipine (NFP), an L-type calcium channel blocker, enhanced the absorption of cefixime in vivo but not in vitro, and it was suggested that neural mechanisms might be involved in the effect of NFP. The aim of the present study was to assess the involvement of the nervous system on the intestinal absorption of cephalexin (CFX). To investigate this, we used a single-pass jejunal perfusion technique in rats. NFP and diltiazem enhanced approximately 2-fold the plasma levels of CFX in treated rats versus untreated controls. NFP also increased approximately 2-fold the CFX level in portal plasma and increased urinary excretion of CFX, thus indicating that CFX did effectively increase CFX intestinal absorption. Perfusing high concentrations of dipeptides in the jejunal lumen competitively reduced CFX absorption and inhibited the enhancement of CFX absorption produced by NFP. Hexamethonium and lidocaine inhibited the effect of NFP, whereas atropine, capsaicin, clonidine, and isoproterenol enhanced CFX absorption by the same order of magnitude as NFP. Thus, complex neural networks can modulate the function of the intestinal di- and tripeptide transporter. Sympathetic noradrenergic fibers, intestinal sensory neurons, and nicotinic synapses are involved in the increase of CFX absorption produced by NFP.  (+info)

Facilitatory beta2-adrenoceptors on cholinergic and adrenergic nerve endings of the guinea pig trachea. (2/784)

Using electrical field stimulation of epithelium-denuded intact guinea pig tracheal tube preparations, we studied the presence and role of prejunctional beta2-adrenoceptors by measuring evoked endogenous acetylcholine (ACh) and norepinephrine (NE) release directly. Analysis of ACh and NE was through two HPLC systems with electrochemical detection. Electrical field stimulation (150 mA, 0.8 ms, 16 Hz, 5 min, biphasic pulses) released 29.1 +/- 2.5 pmol ACh/g tissue and 70.2 +/- 6.2 pmol NE/g tissue. Preincubation for 15 min with the selective beta2-adrenoceptor agonist fenoterol (1 microM) increased both ACh and NE overflow to 178 +/- 28 (P < 0.01) and 165 +/- 12% (P < 0.01), respectively, of control values, increases that were abolished completely by the selective beta2-adrenoceptor antagonist ICI-118551 (1 microM). Further experiments with increasing fenoterol concentrations (0.1-100 microM) and different preincubation periods (1, 5, and 15 min) showed a strong and concentration-dependent facilitation of NE release, with maximum response levels decreasing (from nearly 5-fold to only 2.5-fold of control value) with increasing agonist contact time. In contrast, sensitivity of facilitatory beta2-adrenoceptors on cholinergic nerves to fenoterol gradually increased when the incubation period was prolonged; in addition, a bell-shaped concentration-response relationship was found at 15 min of preincubation. Fenoterol concentration-response relationships (15-min agonist preincubation) in the presence of atropine and yohimbine (1 microM each) were similar in the case of NE release, but in the case of ACh release, the bell shape was lost. The results indicate a differential capacity and response time profile of facilitatory prejunctional beta2-adrenoceptors on adrenergic and cholinergic nerve terminals in the guinea pig trachea and suggest that the receptors on adrenergic nerves are more susceptible to desensitization.  (+info)

Effects of clonidine on myocardial beta-adrenergic receptor-adenyl cyclase-cAMP system after scalds in rats. (3/784)

AIM: To study the role of clonidine (Clo) on the myocardial beta-adrenergic receptor (beta-AR)-adenyl cyclase (AC)-cAMP system after the scalds in rats. METHODS: A 30% skin-full-thickness scald was produced by immersing rats in 95 degrees C water for 9 s. Clo 0.1-3.0 mg.kg-1 was injected i.p. to rats at 30 min before scalds, yohimbine (Yoh) 0.05 mg.kg-1 or prazosin (Pra) 0.03 mg.kg-1 to rats at 30 min before i.p. Clo. beta-AR density and affinity, AC activity, phosphoric diester hydrolases (PDH) activity, and cAMP content were determined with radioreceptor assay, indirect method, enzymeradiochemical assay, and radioimmunoassay, respectively. RESULTS: Clo inhibited the decrease of the myocardial beta-AR density, the attenuation of AC activity, and the reduction of cAMP content at 12 h after the scalds. Yoh partially reversed the effects of Clo on the three parameters. But Pra did not. CONCLUSION: Clo reversed the changes of the myocardial beta-AR-AC-cAMP system resulted from the scalds in rats.  (+info)

Differential potentiation of arachidonic acid release by rat alpha2 adrenergic receptor subtypes. (4/784)

CHO transfectants expressing the three subtypes of rat alpha2 adrenergic receptors (alpha2AR): alpha2D, alpha2B, alpha2C were studied to compare the transduction pathways leading to the receptor-mediated stimulation of phospholipase A2 (PLA2) in the corresponding cell lines CHO-2D, CHO-2B, CHO-2C. The alpha2B subtype stimulated the arachidonic acid (AA) release after incubation of the cells with 1 microM epinephrine, whereas alpha2D and alpha2C gave no stimulation. Calcium ionophore A23187 (1 microM) increased the release by a factor of 2-4 in the three strains. When cells were incubated with both epinephrine and Ca2+ ionophore, the AA release differed greatly between cell lines with strong potentiation in CHO-2B (2-3 times greater than Ca2+ ionophore alone), moderate potentiation in CHO-2D, and no potentiation in CHO-2C. The three cell lines each inhibited adenylylcyclase with similar efficiencies when 1 microM epinephrine was used as the agonist. The potentiation depended on both alpha2AR and Gi proteins since yohimbine and pertussis toxin inhibited the process. Pretreatment of CHO-2B cells with MAFP which inhibits both cytosolic and Ca2+-independent PLA2, reduced the release of AA induced by epinephrine+Ca2+ ionophore to basal value, whereas bromoenol lactone, a specific Ca2+-independent PLA2 inhibitor, had no effect. Preincubation of the cells with the intracellular calcium chelator BAPTA gave a dose-dependent inhibition of the arachidonic acid (AA) release. In CHO cells expressing the angiotensin II type 1 receptor, coupled to a Gq protein, the agonist (10-7 M) produced maximal AA release: there was no extra increase when angiotensin and Ca2+ ionophore were added together. There was no increase in the amount of inositol 1,4, 5-triphosphate following stimulation of CHO-2B, -2C, -2D cells with 1 microM epinephrine. Epinephrine led to greater phosphorylation of cPLA2, resulting in an electrophoretic mobility shift for all three cell lines, so inadequate p42/44 MAPKs stimulation was not responsible for the weaker stimulation of cPLA2 in CHO-2C cells. Therefore, the stimulation of cPLA2 by Gi proteins presumably involves another unknown mechanism. The differential stimulation of cPLA2 in these transfectants will be of value to study the actual involvement of the transduction pathways leading to maximal cPLA2 stimulation.  (+info)

Canine external carotid vasoconstriction to methysergide, ergotamine and dihydroergotamine: role of 5-HT1B/1D receptors and alpha2-adrenoceptors. (5/784)

The antimigraine drugs methysergide, ergotamine and dihydroergotamine (DHE) produce selective vasoconstriction in the external carotid bed of vagosympathectomized dogs anaesthetized with pentobarbital and artificially respired, but the receptors involved have not yet been completely characterized. Since the above drugs display affinity for several binding sites, including alpha-adrenoceptors and several 5-HT1 and 5-HT2 receptor subtypes, this study has analysed the mechanisms involved in the above responses. Intracarotid (i.c.) infusions during 1 min of methysergide (31-310 microg min(-1)), ergotamine (0.56-5.6 microg min(-1)) or DHE (5.6-31 microg min(-1)) dose-dependently reduced external carotid blood flow (ECBF) by up to 46+/-4, 37+/-4 and 49+/-5%, respectively. Blood pressure and heart rate remained unchanged. The reductions in ECBF by methysergide were abolished and even reversed to increases in animals pre-treated with GR127935 (10 microg kg(-1), i.v.). The reductions in ECBF by ergotamine and DHE remained unchanged in animals pre-treated (i.v.) with prazosin (300 microg kg(-1)), but were partly antagonized in animals pre-treated with either GR127935 (10 or 30 microg kg(-1)) or yohimbine (1000 microg kg(-1)). Pre-treatment with a combination of GR127935 (30 microg kg(-1)) and yohimbine (1000 microg kg(-1)) abolished the responses to both ergotamine and DHE. The above doses of antagonists were shown to produce selective antagonism at their respective receptors. These results suggest that the external carotid vasoconstrictor responses to methysergide primarily involve 5-HT1B/1D receptors, whereas those to ergotamine and DHE are mediated by 5-HT1B/1D receptors as well as alpha2-adrenoceptors.  (+info)

Effects of vasopressin on the sympathetic contraction of rabbit ear artery during cooling. (6/784)

In order to analyse the effects of arginine-vasopressin on the vascular contraction to sympathetic nerve stimulation during cooling, the isometric response of isolated, 2-mm segments of the rabbit central ear (cutaneous) artery to electrical field stimulation (1-8 Hz) was recorded at 37 and 30 degrees C. Electrical stimulation (37 degrees C) produced frequency-dependent arterial contraction, which was reduced at 30 degrees C and potentiated by vasopressin (10 pM, 100 pM and 1 nM). This potentiation was greater at 30 than at 37 degrees C and was abolished at both temperatures by the antagonist of vasopressin V1 receptors d(CH2)5 Tyr(Me)AVP (100 nM). Desmopressin (1 microM) did not affect the response to electrical stimulation. At 37 degrees C, the vasopressin-induced potentiation was abolished by the purinoceptor antagonist PPADS (30 microM), increased by phentolamine (1 microM) or prazosin (1 microM) and not modified by yohimbine (1 microM), whilst at 30 degrees C, the potentiation was reduced by phentolamine, yohimbine or PPADS, and was not modified by prazosin. The Ca2+-channel blockers, verapamil (10 microM) and NiCl2 (1 mM), abolished the potentiating effects of vasopressin at 37 degrees C whilst verapamil reduced and NiCl2 abolished this potentiation at 30 degrees C. The inhibitor of nitric oxide synthesis, L-NOARG (100 microM), or endothelium removal did not modify the potentiation by vasopressin at 37 and 30 degrees C. Vasopressin also increased the arterial contraction to the alpha2-adrenoceptor agonist BHT-920 (10 microM) and to ATP (2 mM) at 30 and 37 degrees C, but it did not modify the contraction to noradrenaline (1 microM) at either temperature. These results suggest that in cutaneous (ear) arteries, vasopressin potentiaties sympathetic vasoconstriction to a greater extent at 30 than at 37 degrees C by activating vasopressin V1 receptors and Ca2+ channels at both temperatures. At 37 degrees C, the potentiation appears related to activation of the purinoceptor component and, at 30 degrees C, to activation of both purinoceptor and alpha2-adrenoceptor components of the sympathetic response.  (+info)

Recovery of locomotion after ventral and ventrolateral spinal lesions in the cat. II. Effects of noradrenergic and serotoninergic drugs. (7/784)

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)

Effects of A1-adenosine receptor antagonists on purinergic transmission in the guinea-pig vas deferens in vitro. (8/784)

1. Intracellularly recorded excitatory junction potentials (ej.ps) were used to study the effects of adenosine receptor antagonists on neurotransmitter release from postganglionic sympathetic nerve terminals in the guinea-pig vas deferens in vitro. 2. The A1 adenosine receptor antagonists, 8-phenyltheophylline (10 microM) and 8-cyclopentyl-1,3-dipropylxanthine (0.1 microM), increased the amplitude of e.j.ps evoked during trains of 20 stimuli at 1 Hz in the presence, but not in the absence, of the alpha2-adrenoceptor antagonist, yohimbine (1 microM) or the non-selective alpha-adrenoceptor antagonist, phentolamine (1 microM). 3. Adenosine (100 microM) reduced the amplitude of e.j.ps, both in the presence and in the absence of phentolamine (1 microM). This inhibitory effect of adenosine is most likely caused by a reduction in transmitter release as there was no detectable change in spontaneous ej.p. amplitudes. 4. In the presence of phentolamine, application of the adenosine uptake inhibitor, S-(p-nitrobenzyl)-6-thioinosine (0.1 microM), had no effect on ej.p. amplitudes. 5. The phosphodiesterase inhibitor, 3-isobutyl-1-methylxanthine (100 microM), significantly increased the amplitudes of all e.j.ps evoked during trains of 20 stimuli at 1 Hz, both in the presence and in the absence of phentolamine (1 microM). 6. These results suggest that endogenous adenosine modulates neurotransmitter release by an action at prejunctional A1 adenosine receptors only when alpha2-adrenoceptors are blocked.  (+info)

Stress promotes a shift from goal-directed action-outcome learning toward habitual stimulus-response learning. This shift is mediated by an interaction of noradrenergic activity and glucocorticoid stress hormones. In the present experiment, we examined the neural correlates of the stress (hormone)-induced shift from goal-directed to habit learning in the human brain. Healthy participants were administered hydrocortisone, the α2-adrenoceptor antagonist yohimbine, or both before they were trained in two instrumental actions leading to two distinct food rewards. After training, one of the rewards was devalued by feeding participants to satiety on that food. Finally, participants were presented the two instrumental actions in extinction.

Yohimbine HCL Synonyms: Yohimbin, Corynine, Quebrachin, Quebrachine, Aphrosol, Yohimex, Yohimbe HCL (commonly confused with)What is Yohimbine HCL Powder?Yohimbine is an alkaloid found in Yohimbe, a tall evergreen bark native to Africa. Yohimbine has some exciting possibilities, such as promoting and enhancing erectile function. However, many users primarily take Yohimbine as a fat loss aid.Yohimbine Powder BenefitsYohimbine directly aids weight loss. There are two types of adrenergic receptors, alpha and beta, and depending on which are activated, lipolysis (breakdown of fat) can be either stimulated or inhibited. Activation of the alpha 2 receptors inhibits the release of norepinephrine. This is not good if you are trying to reduce weight. Because alpha 2 receptors activate at lower catecholamine levels than the beta receptors, thermogenesis is basically always turned off. Even during exercise, alpha 2 receptors are still acting to inhibit lipolysis. This is where Yohimbine comes into play. Yohimbine
In the US, yohimbe preparations are sold as a dietary supplements for enhancing libido, for weight loss and as aids for bodybuilding; but There is virtually no published research on yohimbe which supports these or any other claims.[9]:861 Often, these products explicitly claim to contain yohimbine.[8] Cohen et al. found that samples of brands sold in American brick-and-mortar stores contained highly variable amounts of yohimbine, and sometimes none at all.[8]:368 Labelling claims were often misleading.[8]:368 Similar results have been reported by other laboratories for products sold in the U.S., in other countries and on the internet.[15][16][17][18][19] One study found that many brands of yohimbe might not derive from the P. johimbe tree in the first place.[20] According to yet another source the yohimbe sold in markets in West Africa, where the tree grows, is frequently adulterated with other species of the genus Pausinystalia; these contain little yohimbine.[21] The amounts of alkaloid ...
Yohimbine is the principal alkaloid of the bark of the West-African evergreen Pausinystalia yohimbe Pierre (formerly Corynanthe yohimbe), family Rubiaceae (Madder family). There are 31 other yohimbane alkaloids found in Yohimbe. In Africa, yohimbine has traditionally been used as an aphrodisiac.[7] However it is very important to note that while the terms yohimbine, yohimbine hydrochloride, and yohimbe bark extract are related, they are not interchangeable.[8] The active chemical present in yohimbe bark is Yohimbine HCl (indole alkaloid) found in the bark of the Pausinystalia yohimbe tree. However, the levels of yohimbine that are present in yohimbe bark extract are variable and often very low.[1] Therefore, although yohimbe bark has been used traditionally to reduce male erectile dysfunction, there is not enough scientific evidence to form a definitive conclusion in this area. ...

Transdermal application as a viable alternative? About five to ten years ago fat loss gels and cremes were all the rage in the fitness community. These days, however, many topicals carve out a miserable existence in the clearance section of the average supplement store. Wrongfully, if you put some faith into the results Frank L. Greenway and George A. Bray from the UCLA School of Medicine, and the University of Southern California present in a paper from the late 1980s (Greenway. 1987). The results of the corresponding experiments do yet only confirm that it is likely that yohimbine makes an excellent adjunct to a cream thats based on the combination of a beta stimulator with a phosphodiesterase inhibitor (forskolin and aminophylline + yohimbine) - a combination of which Greenway & Bray found that it reduces the thigh circumference by an additonal 2.03 ± 1.36 cm compared to diet alone. The effects of yohimine, alone (dosed at 10mmol/L), which were tested in a seperate experiment, were ...

Yohimbine is an alkaloid found in Yohimbe, a tall evergreen bark native to Africa. Yohimbine has some exciting possibilities, such as promoting and enhancing erectile function and vasodilation for vascularity. However, many users primarily take Yohimbine as a direct aid for fat loss.

Activation of the alpha 2 receptors inhibits the release of norepinephrine. This is not good if you are trying to reduce weight. Because alpha 2 receptors activate at lower catecholamine levels than the beta receptors, thermogenesis is basically always turned off. Even during exercise, alpha 2 receptors are still acting to inhibit lipolysis. This is where Yohimbine comes into play. Yohimbine is a selective alpha 2 antagonist and can short circuit this feedback loop, maximizing norepinephrine levels, and leading to maximized fat loss.. ...
The transdermal formula in LipoBurn is specifically designed to help you lose weight. This is because it specifically targets stores of fat in the body. The thermogenic properties of LipoBurn send lipolytic agents directly to these stores. The agents invade the cells and destroy them allowing you to lose weight in the process! The LipoBurn formula is comprised of specific ingredients that target the fat cells and keep your body healthy in the process. Yohimbine is just one part of LipoBurn. This ingredient serves as an antioxidant. Yohimbine is an adrenergic antagonist of alpha-2. It works to increase the activity of the nervous system while increasing epineprhine levels. Yohimbine is used as a fat burning supplement because it has transdermal properties. Synephrine is an adrenergic agonist of beta-1. This aids in the break down of fat deposits through the process of lipolysis. Synephrine is a known appetite suppressant and like Yohimbine contains thermogenic

Ample experimental evidence supports the existence of two distinct types of vasoconstrictor α-adrenoceptors in vascular smooth muscle at postjunctional sites, showing similarities with α1 and α2-adrenoceptors. Especially in vivo, the characterization of an α2-adrenoceptor mediating an increase in diastolic pressure has been most successful. In this respect the model of the pithed rat has been employed most frequently (for reviews see [1, 2]).. At present, the agents cirazoline, (−) phenylephrine, (±)-erythro-methoxamine, (−)-amidephrine, SKF89748, St587 and Sgd 101/75 fulfil the criteria for selective α1-adrenoceptor agonists; their log dose-vasopressor effect curves are virtually unaffected by previous treatment with yohimbine or rauwolscine (selective dose in pithed rats: 1 mg/kg), whereas prazosin (selective dose in pithed rats: 0.1 mg/kg) causes an appreciable parallel rightward displacement. The reverse holds true for the stimulants B-HT 920, B-HT 933, B-HT 958, UK-14304, ...

... is a selective β2 adrenergic receptor (adrenoreceptor) antagonist or beta blocker[1][2] . ICI binds to the β2 subtype with at least 100 times greater affinity than β1 or β3, the two other known subtypes of the beta adrenoceptor.[3][4] The compound was developed by Imperial Chemical Industries, which was acquired by AkzoNobel in 2008. ICI-118,551 has no known therapeutic use in humans although it has been used widely in research to understand the action of the β2 adrenergic receptor, as few other specific antagonists for this receptor are known.[5] ICI-118,551 has been used in pre-clinical studies using murine models.[6][7][8] When dissolved in saline, the compound crosses the blood-brain barrier. Common systemic doses used in rodent research are 0.5 or 1 mg/kg although efficacy has been demonstrated at doses as low as 0.0001 mg/kg in rhesus monkeys.[9] Doses up to 20 mg/kg have been used without toxicity. At room temperature in saline, the ICI 118,551 hydrochloride is soluble to ...
There are a variety of clinically useful ergoline derivatives for the purpose of vasoconstriction, the treatment of migraines, and treatment of Parkinson's disease. Ergoline alkaloids found their place in pharmacology long before modern medicine as preparations of ergot were often used by midwives in the 12th century to stimulate childbirth.[10] Following Arthur Stoll's isolation of ergometrine, the therapeutic use of ergoline derivatives became well explored. The induction of uterine contractions via the preparation of ergot was attributed to ergonovine, an ergoline derivative found in ergot, which is a powerful oxytocic. From this, methergine, a synthetic derivative, was elucidated.[7] While used to facilitate child birth, ergoline derivatives can pass into breast milk and should not be used during breastfeeding.[11] They are uterine contractors that can increase the risk of miscarriage during pregnancy.[3] Another example of medically relevant ergoline alkaloids is ergotamine, an alkaloid ...
The most common side effect is eye irritation felt as stinging or burning, which occurs in up to a third of patients. Blepharoconjunctivitis occurs in up to 5% of patients. Rarer adverse effects include keratitis, edema and increased lacrimation.[2][3] Allergies are rare, but seem to be more common than under the related drug timolol.[1] If the substance reaches the nasal mucosa via the tear duct, it can be absorbed into the bloodstream and cause systemic side effects. These include orthostatic hypotension (low blood pressure) and other effects on the heart and circulatory system, breathing problems in people with asthma, and skin symptoms such as itching and aggravation of psoriasis.[1] ...

... (INN) is a drug which is used in scientific research. It acts as both a selective α2 adrenergic receptor antagonist, and an antagonist for the imidazoline receptor.[1][2] Idazoxan has been under investigation as an antidepressant, but it did not reach the market as such. More recently, it is under investigation as an adjunctive treatment in schizophrenia. Due to its alpha-2 receptor antagonism it is capable of enhancing therapeutic effects of antipsychotics, possibly by enhancing dopamine neurotransmission in the prefrontal cortex of the brain, a brain area thought to be involved in the pathogenesis of schizophrenia. ...
... , also known as eformoterol, is a long-acting β2 agonist (LABA) used as a bronchodilator in the management of asthma and chronic obstructive pulmonary disease (COPD). Formoterol has an extended duration of action (up to 12 h) compared to short-acting β2 agonists such as salbutamol (albuterol), which are effective for 4 h to 6 h. LABAs such as formoterol are used as "symptom controllers" to supplement prophylactic corticosteroid therapy. A "reliever" short-acting β2 agonist (e.g., salbutamol) is still required, since LABAs are not recommended for the treatment of acute asthma. It was patented in 1972 and came into medical use in 1998.[2] It is also marketed in the combination formulations budesonide/formoterol and mometasone/formoterol. ...
Since silodosin has high affinity for the α1A adrenergic receptor, it causes practically no orthostatic hypotension (in contrast to other α1 blockers). On the other side, the high selectivity seems to be the cause of silodosin's typical side effect of loss of seminal emission.[3] As α1A adrenoceptor antagonists are being investigated as a means to male birth control due to their ability to inhibit ejaculation but not orgasm, a trial with 15 male volunteers was conducted. While silodosin was completely efficacious in preventing the release of semen in all subjects, 12 out of the 15 patients reported mild discomfort upon orgasm. The men also reported the psychosexual side effect of being strongly dissatisfied by their lack of ejaculation.[4] ...
... (MDPPP) is a stimulant designer drug. It was sold in Germany in the late 1990s and early 2000s as an ingredient in imitation ecstasy (MDMA) pills.[1] It shares a similar chemical structure with α-PPP and MDPV,[2][3][4] and has been shown to have reinforcing effects in rats.[5] ...
... (marketed as Hytrin or Zayasel) is a selective alpha-1 antagonist used for treatment of symptoms of an enlarged prostate (BPH). It also acts to lower the blood pressure, and is therefore a drug of choice for men with hypertension and prostate enlargement. It is available in 1 mg, 2 mg, 5 mg or 10 mg doses.[1] It works by blocking the action of adrenaline on smooth muscle of the bladder and the blood vessel walls. Most common side effects include dizziness, drowsiness, headache, constipation, loss of appetite, fatigue, nasal congestion or dry eyes, but they generally go away after only a few days of use. Therapy should always be started with a low dose to avoid first dose phenomenon.[2] Sexual side effects are rare, but may include priapism or erectile dysfunction. ...
... eye drops may cause blurred vision, eye irritation and dilated pupils.[6] Tetryzoline is not suitable for prolonged use as its vasoconstrictive effects within the eye eventually decrease or stop. When body is accustomed to tetryzoline, ceasing its use may cause redness of the eyes.[7] Intranasal use of tetryzoline may cause transient burning, stinging, or dryness of the mucosa and sneezing. Prolonged intranasal use often causes opposite effects in the form of rebound congestion with effects such as chronic redness, swelling and rhinitis. Prolonged use thus may result in overuse of the drug.[6] Overdose most often causes slow heart rate. Respiratory depression, low blood pressure, constricted pupils, hypothermia, brief episodes of high blood pressure,[8] drowsiness, headaches and vomiting may also occur.[9] In serious cases some of these effects may result in circulatory shock.[6] Most often overdoses occur in children who have ingested the drug.[8] There is no antidote for ...

The drug works by stimulating adrenergic receptors on the lamina propria of blood vessels in the nose. The decongestant effect is due to constriction of large veins in the nose which swell up during the inflammation of any infection or allergy of the nose. The smaller arteries are also constricted and this causes the colour of the nasal epithelium to be visibly paler after dosage. Xylometazoline is an imidazole derivative which is designed to mimic the molecular shape of adrenaline. It binds to α1 and α2 adrenergic receptors[8] in the nasal mucosa. Due to its sympathomimetic effects, it should not be used by people with high blood pressure, or other heart problems. Extended usage of xylometazoline can result in decreased effectiveness or a buildup of tolerance against the drug.[9] The number of receptors decreases, and when the administration of the drug is ceased, chronic congestion can occur; this is called rhinitis medicamentosa, commonly referred to as rebound congestion. Moreover, ...
Ipratropium/salbutamol, sold under the brand name Combivent among others, is a combination medication used to treat chronic obstructive pulmonary disease (COPD).[2][3] It contains ipratropium (an anticholinergic) and salbutamol (albuterol, a β2-adrenergic agonist).[2] It is taken by inhalation.[4] Common side effects include sore throat, muscle cramps, and nausea.[2] Other side effects may include bronchospasm, allergic reactions, and upper respiratory tract infections.[2] Safety in pregnancy is unclear.[1] Each medication typically decreases bronchospasm and does so via different mechanisms.[2] The combination was approved for medical use in the United States in 1996.[4] It is available as a generic medication.[3] Sixty doses in the United Kingdom costs the NHS about 18 £ as of 2019.[3] In the United States the wholesale cost of this amount is about US$9.50.[5] In 2016 it was the 166th most prescribed medication in the United States with more than 3 million prescriptions.[6] ...

Adverse drug reactions associated with the use of beta blockers include: nausea, diarrhea, bronchospasm, dyspnea, cold extremities, exacerbation of Raynaud's syndrome, bradycardia, hypotension, heart failure, heart block, fatigue, dizziness, alopecia (hair loss), abnormal vision, hallucinations, insomnia, nightmares, sexual dysfunction, erectile dysfunction and/or alteration of glucose and lipid metabolism. Mixed α1/β-antagonist therapy is also commonly associated with orthostatic hypotension. Carvedilol therapy is commonly associated with edema.[44] Due to the high penetration across the blood-brain barrier, lipophilic beta blockers, such as propranolol and metoprolol, are more likely than other less lipophilic beta blockers to cause sleep disturbances, such as insomnia, vivid dreams and nightmares.[45] Adverse effects associated with β2-adrenergic receptor antagonist activity (bronchospasm, peripheral vasoconstriction, alteration of glucose and lipid metabolism) are less common with ...
... , also known as thymoxamine, is a drug used in urology for the treatment of erectile dysfunction.[1] It is an α1-adrenergic antagonist.[2] In the United Kingdom, Moxisylte is marketed as Opilon (Archimedes Pharma UK Ltd) and is used for the short-term treatment of primary Reynaud's syndrome. This is a condition where the fingers and toes become discoloured and is triggered by responses to cold, or emotional distress. Opilon tablets help by improving blood circulation to the extremities.[3][4] ...
... , also known as α-ethylphenethylamine, Butanphenamine, B or AEPEA,[1] is a stimulant drug of the phenethylamine class. It is a higher homologue of amphetamine, differing from amphetamine's molecular structure only by the substitution of the methyl group at the alpha position of the side chain with an ethyl group.
