<unk>  (also known as d-tubocurarine or DTC) is a toxic alkaloid and skeletal muscle relaxant in the category of non-depolarizing neuromuscular-blocking drugs, used adjunctively in anesthesia to provide skeletal muscle relaxation during surgery or mechanical ventilation. Unlike a number of other related skeletal muscle relaxants, it is now rarely considered clinically to facilitate endotracheal intubation.<unk>  is classified as a long-duration, antagonist for Nicotinic acetylcholine receptor. It is the active agent of one of the forms of curare.
Currently,<unk>  is rarely used as an adjunct for clinical anesthesia because safer alternatives, such as cisatracurium and rocuronium, are available.
