Adrenergic receptors are a class of G protein-coupled receptors that are targets of the catecholamines, especially norepinephrine and epinephrine. Many cells possess these receptors, and the binding of a catecholamine to the receptor will generally stimulate the sympathetic nervous system. The sympathetic nervous system is responsible for the fight-or-flight response, which includes widening the pupils of the eye, mobilizing energy, and diverting blood flow from non-essential organs to skeletal muscle. There are two main groups of adrenergic receptors, α and β, with several subtypes. α receptors have the subtypes α1 and α2. β receptors have the subtypes β1, β2 and β3. All three are linked to Gs proteins, which in turn are linked to adenylate cyclase. Agonist binding thus causes a rise in the intracellular concentration of the second messenger cAMP. Downstream effectors of cAMP include cAMP-dependent protein kinase (PKA), which mediates some of the intracellular events following hormone binding.

    Bethanidine sulfate
    		Antagonist
    Bethanidine sulfate and its ortho-chloro derivative (BW 392C60) are potent adrenergic neurone blockers with sympathomimetic effects similar to bretylium and guanethidine in various animal models, particularly in cats. They inhibit the release of noradrenaline during nerve stimulation and enhance smooth muscle responses to adrenaline and noradrenaline. Bethanidine sulfate increases pressor responses to tyramine, though this effect diminishes with higher doses. Unlike guanethidine, Bethanidine sulfate does not deplete pressor amine content in the iris of cats post-administration. It also briefly inhibits autonomic cholinergic mechanisms and causes temporary neuromuscular paralysis in large doses, contrasting with its prolonged adrenergic neurone blocking effects.
