Pancuronium is a medication classified as a neuromuscular blocker. It is primarily used in medical settings to induce muscle relaxation during surgical procedures or mechanical ventilation. By blocking the action of the neurotransmitter acetylcholine at the neuromuscular junction, pancuronium prevents muscle contractions, allowing for easier intubation and surgery. This drug is administered intravenously and its effects can last for a significant duration, making it useful in various surgical contexts. Pancuronium is often monitored closely by healthcare professionals to ensure patient safety and to manage its effects effectively during and after procedures.
