Laudexium metilsulfate
Laudexium metilsulfate is a neuromuscular blocking drug or skeletal muscle relaxant in the category of non-depolarizing neuromuscular-blocking drugs, used adjunctively in surgical anesthesia to facilitate endotracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation.

Laudexium[1] is no longer used in clinical practice, though it was introduced clinically in the early 1950s. It has about half the potency, a slower onset of action and a duration of action much longer than that of d-tubocurarine.[2] As with all clinically established (as well as experimental agents) with a non-depolarizing mechanism of action, its pharmacological action can be antagonized by anticholinesterases.
The displacement of laudexium from clinical use was assured owing to recurrent reports of significant post-operative re-curarization.[3]
