Atracurium is a non-depolarizing neuromuscular blocking agent used to induce skeletal muscle relaxation during surgery or mechanical ventilation. It acts by competing with acetylcholine for nicotinic receptors at the neuromuscular junction. Atracurium is approved and widely used in clinical anesthesia.
Pharmacokinetics
Pharmacokinetic parameters reported for healthy adult surgical patients (age 18-65) of both sexes undergoing general anesthesia.
