Pancuronium

Published: July 26, 2026Updated: August 24, 2026

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.

Quick summary

Pancuronium is a muscle relaxant used during surgery and ventilation to temporarily paralyze muscles.

Overdose information

Important overdose information
Toxic dose: Single dose exceeding 10 mg may cause serious toxicity and prolonged neuromuscular blockade
Chronic overdose: Prolonged use in ICU settings leading to cumulative effects and extended paralysis
Immediate actions
Maintain airway and ventilation, provide oxygen support, consider reversal agents, monitor cardiac function
Antidote
Sugammadex or Neostigmine with Glycopyrrolate(Effective when administered promptly, sugammadex preferred for rapid reversal)
Poison Control: 1-800-222-1222

mechanismFDA
2023

Mechanism of action

Value:Competitive antagonism at nicotinic acetylcholine receptors

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.
