A neuromuscular relaxant with short duration of action which characteristically first depolarizes the motor endplate (phase I block) but which is often later associated with a curare-like, nondepolarizing neuromuscular block (phase II block); used to produce relaxation for tracheal intubation and during surgical anesthesia. SYN: diacetylcholine, suxamethonium.
