Pancuronium
Pancuronium is a non-depolarizing neuromuscular blocking agent used to relax muscles during surgical procedures and mechanical ventilation. It works by competitively blocking acetylcholine receptors at the neuromuscular junction, resulting in temporary paralysis. This medication is primarily used as an adjunct to general anesthesia in adult patients requiring endotracheal intubation or surgical procedures.
Pancuronium is a muscle relaxant used during surgery and ventilation to temporarily paralyze muscles.

Mechanism of action
Pharmacological mechanism
Used to facilitate endotracheal intubation, provide skeletal muscle relaxation during surgical procedures, and improve ventilation in patients requiring mechanical support.
Acts as a competitive antagonist at nicotinic acetylcholine receptors in the neuromuscular junction, blocking the binding of acetylcholine and preventing muscle contraction.
Must be administered by trained healthcare professionals with airway management expertise. Requires adequate sedation and analgesia as this medication does not affect consciousness or pain perception. Use with caution in patients with hepatic or renal impairment. Should be stored at controlled temperatures and protected from light.
Contraindications
