Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of nicotinic acetylcholine receptors at the neuromuscular junction, preventing acetylcholine binding and inducing skeletal muscle paralysis.
Competitive antagonist at nicotinic acetylcholine receptors at the neuromuscular junction, preventing acetylcholine binding and muscle contraction.
0.08-0.1 mg/kg IV bolus for intubation; maintenance 0.01-0.015 mg/kg IV every 30-60 min as needed or continuous infusion at 0.06-0.12 mg/kg/hr.
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 is approximately 1.3-2.2 hours in adults; prolonged in hepatic or renal impairment (up to 3-4 hours in renal failure).
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.
Approximately 40-50% of the dose is excreted unchanged in urine within 24 hours; 20-30% is eliminated in feces as unchanged drug and metabolites; minor biliary excretion.
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.
