how does d-tubocurarine act as a muscle relaxant
Tubocurarine chloride Because of the shortcomings of tubocurare, much research effort was undertaken soon after its clinical introduction to find a suitable replacement. The efforts unleashed a multitude of compounds borne from structure-activity relations developed from the tubocurare molecule. Some key compounds that have seen clinical use are identified in the muscle relaxants template box below. Of the many tried as replacements, only a few enjoyed as much popularity as tubocurarine: pancuronium, vecuronium, rocuronium, atracurium, and cisatracurium. Succinylcholine is a widely used muscle relaxant drug which acts by activating, instead of blocking, the ACh receptor.
