tcsc2535 Pancuronium (dibromide)

Pancuronium Dibromide is a bis-quaternary steroid that is a competitive nicotinic antagonist.

Target: nAChR

Pancuronium dibromide is a competitive AChR antagonist (IC50 = 5.5 nM) and acts as a skeletal muscle relaxant. Pancuronium dibromide interrupts neuromuscular transmission by competing with acetylcholine for receptor sites on the motor end-plate. Pancuronium dibromide is a non-depolarizing agent. Pancuronium is a typical non-depolarizing curare-mimetic muscle relaxant. It acts as a competitive acetylcholine antagonist on neuromuscular junctions, displacing acetylcholine (hence competitive) from its post-synaptic nicotinic acetylcholine receptors. It is (unlike suxamethonium) a non-depolarizing agent, which means that it causes no spontaneous depolarizations upon association with the nicotinic receptor in neuromuscular junction, thus producing no muscle fasciculations upon administration [1-3].
