Vecuronium bromide

Vecuronium is a non-depolarizing muscle relaxant derived from the aminosteroid pancuronium and used adjunctively to general anesthesia. It competitively blocks cholinergic receptors at the motor end plate of the neuromuscular junction, inducing temporary paralysis. In humans, it has been shown to reduce muscle twitch tension with an ED₅₀ value of 0.15 mg/kg for a duration of 27 minutes without inducing cardiovascular effects.
