Mechanism of Action
Cisatracurium competitively binds to nicotinic cholinergic receptors at the neuromuscular junction, preventing acetylcholine binding and blocking muscle contraction. It is metabolized via Hofmann elimination—organ-independent—making it suitable for varied preclinical models.
Research Applications & Pharmacology
Muscle relaxation models: Suitable for tracheal intubation, ventilation, and anesthesia simulation .
Pharmacokinetics: Onset ~2–4?min; effective duration ~55?min; half-life ~20–30?min; slower onset in geriatrics or renal impairment .
Comparative profile: Less histamine release and hemodynamic impact than atracurium, with faster recovery compared to vecuronium.
Safety Profile & Handling
Adverse events: Minimal histamine-mediated reactions (flushing, hypotension); rare bronchospasm .
Hypersensitivity: Anaphylaxis reported—emergency protocols required .
Lab use guidance: Administer IV with neuromuscular monitoring (e.g., train-of-four), maintain ventilatory support, have resuscitation and reversal agents available .
