Recently i hear the kind of drug from friend,but i don not know the usage and side effect about people .I look for some information about the drug from the web as floowing:

Cisatracurium Besylate is an intermediate-acting, nondepolarizing, neuromuscular blocker that is considered intermediate in onset and duration of action relative to other neuromuscular blockers. It is one of several isomers of atracurium and is three times as potent as atracurium. Both Cisatracurium Besylate and atracurium are often used in patients with multisystem organ failure since their metabolism is independent of hepatic or renal function. Cisatracurium Besylate can be used safely in patients with cardiovascular disease. Clinical uses include skeletal muscle relaxation, facilitation of tracheal intubation in combination with general anesthesia, and skeletal muscle relaxation in ICU patients requiring mechanical ventilation.

If you have accurate and new information ,plesae share with everyone.
