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 from binding and thus inhibiting muscle contraction.
Competitive antagonist of nicotinic acetylcholine receptors at the neuromuscular junction, preventing acetylcholine from binding and causing muscle relaxation.
0.04-0.1 mg/kg IV initial bolus, then 0.01-0.02 mg/kg IV every 20-40 min as needed for neuromuscular blockade.
Initial: 0.3-0.6 mg/kg IV bolus. Maintenance: 0.1-0.2 mg/kg every 20-45 minutes as needed. Alternatively, continuous infusion: 0.005-0.01 mg/kg/min (5-10 mcg/kg/min).

Terminal elimination half-life: 100-120 minutes in adults with normal renal function; prolonged to 240-480 minutes in renal failure.
Terminal elimination half-life: approximately 20 minutes (range 15-30 min). Clinically, this short half-life results in rapid spontaneous recovery after discontinuation, making it suitable for continuous infusion.
Renal: 50-70% unchanged; biliary/fecal: 5-10% as metabolites; minor hepatic metabolism.
Renal (approximately 50-60% as unchanged drug and metabolites); biliary/fecal (minor, <10%); Hofmann elimination (non-enzymatic degradation) and ester hydrolysis contribute to clearance. Total excretion is predominantly renal.
