  • pharmaceutical

Pharmacology

Pancuronium Bromide is the bromide salt form of pancuronium, a synthetic, long-acting ammonio steroid muscle relaxant with curarimimetic, some antimuscarinic and sympathomimetic effects. Pancuronium bromide competitively binds to the nicotinic receptor at the neuromuscular junction, thereby preventing acetylcholine binding and resulting in skeletal muscle relaxation and paralysis.

How it is made

Prepared by reaction of 2alpha, 3alpha: 16alpha, 17alpha-diepoxy- 17beta-acetoxy-5alpha-androstane with piperidine, and subsequent alkylation with methyl bromide.
