Guanidine Hydrochloride

Guanidine Hydrochloride is the hydrochloride salt form of guanidine, a strong basic compound with parasympathomimetic activity. Guanidine hydrochloride enhances the release of acetylcholine following a nerve impulse and potentiates acetylcholine actions on muscarinic and nicotinic receptors. It also appears to slow the rates of depolarization and repolarization of muscle cell membranes. (NCI05) — NCI Thesaurus (NCIt)
