Mechanism of action

Succinylcholine mimics acetylcholine and binds to nicotinic receptors on the motor end plate, causing initial depolarization and visible fasciculations followed by sustained depolarization that prevents repolarization and muscle contraction. This results in rapid onset paralysis lasting several minutes, making it useful for rapid sequence intubation and short procedures. The drug is metabolized by plasma cholinesterase, allowing for relatively quick recovery.
