  • Title: Antagonism of org NC 45 (vecuronium) and pancuronium neuromuscular blockade by neostigmine.
    Author: Gencarelli PJ, Miller RD.
    Journal: Br J Anaesth; 1982 Jan; 54(1):53-6. PubMed ID: 6119998.
    Abstract:
    The antagonism, by neostigmine, of neuromuscular blockade produced by either Org NC 45 or pancuronium was studied in 29 anaesthetized patients during a continuous infusion of the myoneural blocker. The ED50 of neostigmine (dose which produced a 50% antagonism) when antagonizing Org NC 45 and pancuronium was 0.011 mg kg-1 and 0.010 mg kg-1 respectively. The dose-response relationships for the antagonism of Org NC 45 and pancuronium neuromuscular blockades were not significantly different. The duration of the effect of neostigmine was not different when antagonizing an Org NC 45- or pancuronium-induced blockade. We concluded that Org NC 45 and pancuronium are effectively and equally (independent of pharmacokinetics) antagonized by neostigmine in man.
