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 neurotransmission and inducing muscle relaxation.
Competitive antagonist at nicotinic acetylcholine receptors at the neuromuscular junction, blocking acetylcholine binding and inhibiting neuromuscular transmission, resulting in skeletal muscle paralysis.
0.15-0.2 mg/kg IV bolus for intubation; maintenance infusion 1-2 mcg/kg/min (initial) adjusted to effect.

Terminal elimination half-life approximately 20-30 minutes in healthy adults; prolonged in hepatic or renal impairment.
Terminal elimination half-life is approximately 20-30 minutes (mean 24 minutes) in patients with normal renal and hepatic function; clinically, this short half-life supports rapid recovery after discontinuation and suitability for continuous infusion.
Primarily renal (80% as unchanged drug and metabolites); biliary/fecal excretion accounts for <20%.
Primarily via Hofmann elimination (approximately 80%) and ester hydrolysis by nonspecific plasma esterases; renal excretion of unchanged drug accounts for less than 5% of the dose, and biliary/fecal elimination is minimal (less than 1%).
