Indication: Intravenous Muscle relaxant in general anaesthesia, Endotracheal intubation, Aid controlled ventilation Adult: Initially, 300-600 mcg/kg as inj.

Alternatively, maintenance can also be achieved by continuous infusion at 5-10 mcg/kg/minute. Initial dose should be given over 60 seconds in patients with CV disease. Dose should be calculated based on ideal body-weight in obese patients. Special Populations: For patients with significant CV disease or any history (e.g. severe anaphylactoid reactions or asthma) suggesting a greater risk of histamine release, an initial dose of 0.3-0.4 mg/kg should be given... Administration: Mixed block with suxamethonium which is difficult to reverse with anticholinergic drugs. Ketamine may potentiate the effects of atracurium. Concurrent use with tamoxifen or danazol may prolong effects of atracurium.

Malignant hyperthermia with halogenated anaesthetics and succinylcholine. MAOIs. Adult Dose: Neonates; severe CVS disorders; renal or hepatic dysfunction; myasthenia gravis and other neuromuscular disorders; severe electrolyte imbalances; respiratory insufficiency or pulmonary disease, asthma; burns; cardiopulmonary bypass; smoking; pregnancy and lactation. Dosage for obese patients should be based on ideal body-weight to prevent overdosing. Renal Dose: Atracurium besilate blocks neural transmission at the neuromuscular junction by competitive binding at the cholinergic receptor sites on the motor end plate. Contraindication: Intravenous Muscle relaxant in general anaesthesia, Endotracheal intubation, Aid controlled ventilation Child: >2 mth: Initially, 400-500 mcg/kg as inj. Maintenance dose: 80-100 mcg/kg; first maintenance dose may be given 20-45 min after the initial dose, subsequently, may be repeated every 15-25 min.
