Depolarizing Neuromuscular

The only depolarizing neuromuscular-blocking drug in clinical use is SCh. SCh rapidly produces intense paralysis(30 to 60 s) and has a short duration of action(3 to5 minutes).These characteristics make Scha useful drug for providing skeletal muscle relaxation to facilitate the intubation of the trachea. SCh has several associated adverse effects that can limit or even contraindicate its use.
