Atracurium is indicated for endotracheal intubation, facilitate mechanical ventilation in intensive care, muscle relaxant in general anaesthesia.

Adult and Child (>1 month): Initially, 300-600 mcg/kg as bolus IV, with subsequent doses of 100-200 mcg/kg by IV every 15-25 min or 5-10 mcg/kg/min by infusion in prolonged procedures. Higher infusion rate may be used in patients undergoing controlled ventilation in intensive care.

Atracurium is contraindicated in patients known to be hypersensitive to atracurium, cisatracurium or benzenesulfonic acid. In common with all the other neuromuscular blocking agents, atracurium besilate paralyses the respiratory muscles as well as other skeletal muscles but has no effect on consciousness.

Skin flush, erythema, pruritus, urticaria, wheezing, increased bronchial secretions, bronchospasm, cyanosis, angioedema, CV effects (e.g. bradycardia); wheals and erythema at inj site. Potentially Fatal: Anaphylaxis.

Overdose Effects

Stimulation of histamine release, CV effects especiall hypotension

Patient with CV disease, burn injury, asthma; conditions which may antagonise neuromuscular blockade (e.g. resp alkalosis, hypercalcaemia, demyelinating lesions, peripheral neuropathies, denervation, muscle trauma); conditions which may potentiate neuromuscular blockade (e.g. electrolyte abnormalities, neuromuscular diseases, metabolic acidosis, resp acidosis, Eaton-Lambert syndrome, myasthenia gravis). Pregnancy and lactation.

Pregnancy & Lactation

Pregnancy Category C: Teratogenic Effects. Atracurium besylate has been shown to be potentially teratogenic in rabbits when given in doses up to approximately one-half the human dose. There are no adequate and well-controlled studies in pregnant women. Atracurium should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
