| pancuronium | <chemical> A bis-quaternary steroid that is a competitive nicotinic antagonist. As a neuromuscular blocking agent it is more potent than curare but has less effect on the circulatory system and on histamine release. Pharmacological action: neuromuscular nondepolarising agents, nicotinic antagonists. Chemical name: Piperidinium, 1,1'-((2beta,3alpha,5alpha,16beta,17beta)-3,17-bis(acetyloxy)androstane-2,16-diyl)bis(1-methyl-, dibromide (12 Dec 1998) |
