Pancuronium is a steroid compound that does not possess hormonal activity. It is used in anesthesiology as a myorelaxant, causing prolonged muscle relaxation during surgical interventions of the thoracic and abdominal cavities, in proctology, ophthalmology, orthopedic practice, and in heart surgeries. A synonym of this drug is pavulon.
Vecuronium: Vecuronium, 1-[(2/i,3a,5a,16/U7/i,)-3,17-bis(acetyloxy)-2-(1-piperidinyl) androstan-16-yl]-1-methylpiperidinium bromide (15.1.9), differs from panuronium only in the extent of alkylation. Only the piperidine substituent on C16 of the steroid skeleton is transformed into a quaternary salt [15,16].
