NCI Drug Dictionary


cisatracurium besylate 
A non-depolarizing skeletal muscle relaxant of the benzylisoquinolinium class. Cisatracurium besylate acts as a competitive acetylcholine antagonist that binds to nicotinic receptors at the neuromuscular junction. Compared to other neuromuscular blocking agents, it is intermediate in its onset and duration of action. Cisatracurium besylate is used to maintain neuromuscular relaxation during major surgical procedures, primarily to facilitate endotracheal intubation. Cisatracurium besylate can cause bronchospasms, hypotension, and bradycardia. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
