Mechanism of action

Atracurium binds to nicotinic acetylcholine receptors at the motor end plate, preventing acetylcholine from binding and triggering muscle contraction. This results in flaccid paralysis of skeletal muscles. Atracurium is metabolized by Hofmann elimination (temperature and pH-dependent degradation) and ester hydrolysis, making it suitable for patients with hepatic or renal impairment.
