Vecuronium bromide (Brand name: Norcuron) is a drug which can be supplied to general anesthesia to keep skeletal muscle relaxation during the surgery or mechanical ventilation. It can also be used to help with endotracheal intubation. It has rapid onset (within 4 minutes) and has its effect last for 4 hour. Its mechanism of action is through competitively binding to the nicotinic cholinergic receptors, further antagonizing the opportunity for acetylcholine from binding to the nicotinic receptor at the postjunctional membrane of the myoneural junction. This process prevents the depolarization and the release of calcium ions, stopping muscle contraction and help muscle relaxation.
