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 neuromuscular transmission, resulting in skeletal muscle paralysis.
Competitive antagonist of nicotinic acetylcholine receptors at the neuromuscular junction, preventing acetylcholine from binding and thus inhibiting muscle contraction.
0.15-0.2 mg/kg IV bolus for intubation; maintenance: 1.5-2 mcg/kg/min IV infusion
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.

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.
Terminal elimination half-life: 100-120 minutes in adults with normal renal function; prolonged to 240-480 minutes in renal failure.
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%).
Renal: 50-70% unchanged; biliary/fecal: 5-10% as metabolites; minor hepatic metabolism.
