depolarizing muscle relaxant

Quick Reference

A drug that binds to the acetylcholine receptors at the neuromuscular junction and activates them, thereby causing depolarization. Acetylcholine would have the same effect if present at very high (nonphysiological) concentrations. Suxamethonium, the only commonly used drug of this type, will produce a brief period of paralysis and relaxation.
