Cisatracurium Besylate

**Semantic type:** Pharmacologic Substance

**Definition:** The besylate salt form of cisatracurium, a non-depolarizing skeletal muscle relaxant of the benzylisoquinolinium class, with skeletal muscle relaxing activity. Cisatracurium besylate acts as a competitive acetylcholine antagonist that binds to nicotinic receptors at the neuromuscular junction. This blocks neuromuscular transmission and causes neuromuscular relaxation.
