At a glance

Atracurium Besilate is a non-depolarizing neuromuscular blocking agent used to facilitate endotracheal intubation, mechanical ventilation, and muscle relaxation during surgery.

Description

An injectable skeletal muscle relaxant that competitively blocks acetylcholine receptors at the neuromuscular junction, providing controlled muscle paralysis.

Indications

Indicated for endotracheal intubation, facilitating mechanical ventilation in intensive care, and as a muscle relaxant in general anaesthesia.

Therapeutic class

Non depolarizing muscle relaxants

Pharmacological class

Non-depolarizing Neuromuscular Blocker

Pharmacology

Antagonizes acetylcholine at the motor end-plate cholinergic receptors. Neuromuscular blockade can be reversed by acetylcholinesterase inhibitors like neostigmine.

Mechanism of action

Competitively binds to nicotinic acetylcholine receptors on the motor end-plate, preventing depolarization.

Dosage

Adult and Child (>1 month): Initially 300-600 mcg/kg as IV bolus, with maintenance doses of 100-200 mcg/kg IV every 15-25 min or 5-10 mcg/kg/min by infusion.

Intravenous administration under clinical supervision.

Missed dose

Administered strictly in clinical settings.

Flush, erythema, pruritus, urticaria, wheezing, bronchospasm, bradycardia, injection site reactions. Potentially fatal: Anaphylaxis.
