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, blocking neurotransmission and causing skeletal muscle paralysis.
0.15-0.2 mg/kg IV bolus for intubation; maintenance: 1.5-2 mcg/kg/min IV infusion
0.1-0.2 mg/kg IV bolus for paralysis, repeat 0.05-0.1 mg/kg as needed; maintenance infusion 0.5-1.5 mcg/kg/min IV.

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 half-life: 2-5 hours (prolonged with renal impairment; up to 10 hours in severe impairment)
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%).
Primarily renal excretion (50-70% unchanged drug), with biliary/fecal elimination (10-20%)
