Which of the following is a depolarizing neuromuscular blocker?
Rocuronium
Vecuronium
Succinylcholine
Cisatracurium
Succinylcholine is the only depolarizing neuromuscular blocking agent currently used. It causes depolarization by acting like acetylcholine at the neuromuscular junction. The other listed agents are non-depolarizing agents that work by blocking the acetylcholine receptor.
