Atracurium

Atracurium (BW-33A free acid) is a potent, competitive, non-depolarizing neuromuscular blocking agent and AChR receptor antagonist that induces bronchoconstriction and neuromuscular blockade, while also promoting astroglial differentiation [1] [2] [3] [4] [5].

Atracurium besylate (51W89) is a non-depolarizing neuromuscular blocking agent with short duration of action. Its lack of significant cardiovascular effects and its lack of dependence on good kidney function for elimination provide clinical advantage over alternate non-depolarizing neuromuscular blocking agents.

Cisatracurium besylate (51W89) is a nondepolarizing skeletal muscle relaxant intended for intravenous administration.

DL-Laudanosine (Laudanosine) is a recognized metabolite of atracurium and cisatracurium.
