Atracurium Besylate is a neuromuscular blocking agent with ED95 of 0.2 mg/kg. Target: nAChRAtracurium besylate is a neuromuscular-blocking drug or skeletal muscle relaxant in the category of non-depolarizing neuromuscular-blocking drugs, used adjunctively in anesthesia to facilitate endotracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation. Atracurium is classified as an intermediate-duration non-depolarizing neuromuscular-blocking agent [1]. A 14C radiolabeled metabolism study in cats confirmed the lack of hepatic or renal involvement in the metabolism of atracurium: radioactivity eliminated in bile and urine was predominantly from metabolites rather than the unchanged parent drug [2].
