Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist at nicotinic acetylcholine receptors at the neuromuscular junction, blocking acetylcholine binding and inhibiting muscle contraction.
Competitive antagonist at nicotinic acetylcholine receptors at the neuromuscular junction, preventing acetylcholine binding and muscle contraction.
0.6 mg/kg IV bolus for intubation; maintenance: 0.1-0.2 mg/kg IV bolus as needed or continuous infusion 5-10 mcg/kg/min.
IV bolus: 0.08-0.1 mg/kg for intubation; maintenance: 0.01-0.015 mg/kg every 12-15 minutes as needed or continuous infusion 0.05-0.1 mg/kg/hour.

Terminal elimination half-life: 1.4-2.4 minutes (distribution half-life: 3-5 minutes); recovery index (25-75%): 12-16 minutes; clinical duration (dose-dependent): 30-45 minutes (0.6 mg/kg) to 70-90 minutes (1.2 mg/kg)
Terminal elimination half-life: 1.2-1.9 hours (65-115 minutes). Clinically, recovery from neuromuscular blockade is faster than with pancuronium; prolonged in renal and hepatic impairment.
Renal: 33% unchanged; Biliary/fecal: 33% (as parent and metabolite); Hepatic metabolism: ~10-20%; remainder: unknown
Primarily renal (40-60% unchanged in urine within 24 hours); biliary/fecal elimination accounts for <20%. Approximately 10-20% as 3-desacetylvecuronium (active metabolite) in urine.
