pancuronium

Pancuronium is an aminosteroid antagonist of muscle-type nicotinic acetylcholine receptors (nAChRs) with an IC50value of 14.8 nM using patch clamp electrophysiology in BOSC23 cells expressing mouse nAChRs.1It acts as a non-depolarizing neuromuscular blocking agent.2Pancuronium enhances anesthesia induced by isoflurane , reducing immobilization with an ED50value of 1.62 μg kg.3 1.Liu, M., and Dilger, J.P.Site selectivity of competitive antagonists for the mouse adult muscle nicotinic acetylcholine receptorMol.

Pancuronium dibromide (Pavulon) 是一种双季基类固醇，是一种神经肌肉松弛剂。它通过与乙酰胆碱竞争 nACh 受体上的结合位点来抑制神经肌肉传递。它还可抑制心脏毒蕈碱受体并具有拟交感神经作用。

Dacuronium is a new steroidal drug of neuromuscular blocking properties. Dacuronium produced a competitive type of neuromuscular block with a potency of approximately one-tenth that of tubocurarine and one-fiftieth that of pancuronium.
