Mecamylamine Hydrochloride

개요Mecamylamine hydrochloride is a non-competitive nicotinic acetylcholine receptor antagonist with preferential activity at the α3β4 subtype (IC50 = 90-640 nM) compared to α4β2, α3β2, and α7 subtypes (IC50 range from 1-7 μM), previously used to treat hypertension.Displays antidepressant-like effects in mice.Mecamylamine HCl is supplied as tablets for oral use, each containing 2.5 mg mecamylamine HCl. Inactive ingredients are calcium phosphate, D&C Yellow 10, FD&C Yellow 6, lactose, magnesium stearate, cornstarch, and talc.

용도Mecamylamine hydrochloride has been used as an additive in extracellular saline during current-clamp recordings to reduce synaptic input. It has also been used as a non-selective nicotinic acetyl choline receptor blocker in aortic body neurons and in MLO-Y4 cells.

용도Currently, mecamylamine is the only ganglioblocker used for general hypertension; however, the need has declined because of the possibility of addiction and the introduction of many other antihypertensive drugs into medical practice.

일반 설명The secondary aminemecamylamine hydrochloride, N,2,3,3-tetramethyl-2-norbornanaminehydrochloride (Inversine), has a powerful ganglionicblocking effect that is almost identical to that ofhexamethonium. It has an advantage over most of the ganglionicblocking agents in being absorbed readily andsmoothly from the GI tract. It is rarely used, however, forthe treatment of moderate-to-severe hypertension becausesevere orthostatic hypotension occurs when the drug blockssympathetic ganglia.
