Besipirdine reduces schedule-induced thirst and enhances cholinergic and adrenergic neurotransmission in the central nervous system.

Besipirdine hydrochloride is a non-receptor-dependent cholinomimetic compound with alpha-adrenergic and cardiovascular activities.Besipirdine hydrochloride inhibits voltage-dependent sodium-potassium channels and inhibits biogenic amine uptake.Besipirdine hydrochloride reduces schedule-induced thirst and enhances cholinergic and adrenergic neurotransmission in the central nervous system in rats.

Perphenazine dihydrochloride is an orally active dopamine receptor and histamine-1 receptor antagonist that acts on D2 (Ki: 0.56 nM), D3 (Ki: 0.43 nM), and 5-HT2A (Ki: 0.6 nM) receptors, and also binds Alpha-1A adrenergic receptors. It can induce apoptosis, inhibit cancer cell proliferation, and is used to study psychiatric disorders, cancer, and inflammation.

Quinidine hydrochloride monohydrate is an optical isomer of quinine, extracted from the bark of the Cinchona tree and similar plant species. It prolongs cellular action potential and decreases automaticity. This alkaloid dampens the excitability of cardiac and skeletal muscles by blocking sodium and potassium currents across cellular membranes. Quinidine also blocks muscarinic and alpha-adrenergic neurotransmission.

Methyldopa (MK-351), an alpha-adrenergic agonist (selective for α2-adrenergic receptors) psychoactive medicine, is served as an antihypertensive or sympatholytic.

Mianserin hydrochloride (Org GB 94) is a tetracyclic compound with antidepressant properties that blocks alpha-adrenergic, histamine H1, and certain serotonin receptors; it may cause drowsiness and hematological issues.

Norepinephrine bitartrate acts directly on the α- and β-adrenergic receptors. Norepinephrine Bitartrate is a bitartrate salt of norepinephrine, a synthetic phenylethylamine that mimics the sympathomimetic actions of the endogenous norepinephrine. Clinically, norepinephrine is used as a peripheral vasoconstrictor that causes constriction of arterial and venous beds via its alpha-adrenergic action. It is also used as a potent inotropic and chronotropic stimulator of the heart mediated through its beta-1 adrenergic action.

Prazosin hydrochloride (Vasoflex) reduces peripheral resistance and relaxes vascular smooth muscles as a selective adrenergic alpha-1 antagonist by a mechanism not completely known. Prazosin hydrochloride is a synthetic piperazine derivative with hypotensive antiadrenergic properties, It is used in the treatment of heart failure, hypertension, pheochromocytoma, Raynaud's syndrome, prostatic hypertrophy, and urinary retention.

Norepinephrine bitartrate monohydrate (Levophed) is a direct alpha-adrenergic receptors stimulator.

Phenoxybenzamine hydrochloride (NCI-c01661) is the hydrochloride salt form of phenoxybenzamine, a synthetic, dibenzamine alpha-adrenergic antagonist with antihypertensive and vasodilatory properties. Phenoxybenzamine non-selectively and irreversibly blocks the postsynaptic alpha-adrenergic receptor in smooth muscle, thereby preventing vasoconstriction, relieving vasospasms, and decreasing peripheral resistance. Reflex tachycardia may occur and may be enhanced by blockade of alpha-2 receptors which enhances norepinephrine release. Phenoxybenzamine is reasonably anticipated to be a human carcinogen.

Phentolamine mesylate (Phentolamine methanesulfonate) is a nonselective alpha-adrenergic antagonist used to treat hypertension and hypertensive emergencies, pheochromocytoma, vasospasm of [RAYNAUD DISEASE] and frostbite, clonidine withdrawal syndrome, impotence, and peripheral vascular disease.

Synephrine (Oxedrine) is sympathetic alpha-adrenergic agonist used as a vasoconstrictor in circulatory failure, asthma, nasal congestion, and glaucoma.

Amoxapine (CL-67772) exerts its antidepressant effect by inhibiting the re-uptake of norepinephrine and, to a lesser degree, of serotonin, at adrenergic nerve endings and blocks the response of dopamine receptors to dopamine. Amoxapine is a tricyclic antidepressant of the dibenzoxazepine class. This drug is used to treat symptoms of depression and may cause tardive dyskinesia. Amoxapine also binds to alpha-adrenergic, histaminergic, and cholinergic receptors which accounts for many of the side effects seen with this agent.

Dopamine hydrochloride (ASL279), a naturally occurring catecholamine formed by decarboxylation of dihydroxyphenylalanine and a precursor of norepinephrine and epinephrine, binds to alpha-1- and beta-1- adrenergic receptors.

Yohimbine hydrochloride (Antagonil) is a plant alkaloid with alpha-2-adrenergic blocking activity. Yohimbine has been used as a mydriatic and in the treatment of ERECTILE DYSFUNCTION.

Guanfacine hydrochloride (Intuniv) is a centrally acting antihypertensive agent with specificity towards ADRENERGIC ALPHA-2 RECEPTORS.

Dexmedetomidine is a Central alpha-2 Adrenergic Agonist. The mechanism of action of dexmedetomidine is as an Adrenergic alpha2-Agonist. The physiologic effect of dexmedetomidine is by means of General Anesthesia.

Methyldopa hydrate (MK-351 hydrate) is a DOPA decarboxylase inhibitor and indirect α2-adrenergic receptor agonist used to treat hypertension. It inhibits the sympathetic nervous system, decreases production of dopamine, norepinephrine, and epinephrine, and exhibits NO-dependent sedative activity.
