Which of the following neuromuscular blocking agents is a depolarizing blocker?
Show answer and explanation
Correct answer: Succinylcholine
Succinylcholine is the only commonly used depolarizing neuromuscular blocker. It mimics acetylcholine at nicotinic receptors, causing persistent depolarization of the motor end plate and preventing further muscle contraction.
