Commercial preparations of atracurium are mixtures of 10 stereoisomers, of which cisatracurium generally constitutes about 15%. Cisatracurium besylate is about 3 times more potent than the mixture of atracurium isomers as a neuromuscular blocking agent, and is used as a muscle relaxant for endotracheal intubation, to aid controlled ventilation, and in general anaesthesia. It has a role as a muscle relaxant and a nicotinic antagonist. It is a quaternary ammonium salt, an atracurium besylate and an organosulfonate salt. It contains a cisatracurium."}]
