Cisatracurium besylate

Описание

Cisatracurium besylate is a new intermediate-duration non-depolarizing muscle relaxant launched in the U.S.A. for intubation and maintenance of muscle relaxation during surgery and intensive care. Cisatracurium besylate is the single 1 R cis-1'R cis isomer of the commercial preparation of atracurium, a mixture of 10 isomers. It is 3 to 5 times more potent than the mixture with similar onset and duration of action. The single isomer was also reported to have reduced propensity to release histamine and have a stable cardiovascular profile. Similar to structurally related mivacurium, cisatracurium has distinct advantages of rapid degradation, enzymatic metabolism that is independent of liver or kidney resulting in short duration of action and fast, complete recovery.

Использование

Cisatracurium Besylate is a nondepolarizing neuromuscular blocking agent, antagonizing the action of acetylcholine by inhibiting neuromuscular transmission.

Определение

ChEBI: The (1R,1'R,2R,2'R)-diastereoisomer of atracurium besylate. Commercial preparations of atracurium are mixtures of 10 stereoisomers, of which cisatracurium generally constitutes about 15%. isatracurium 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.
