Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of nicotinic acetylcholine receptors at the neuromuscular junction, blocking neurotransmission and causing skeletal muscle paralysis.
Competitive antagonist of nicotinic acetylcholine receptors at the neuromuscular junction, blocking depolarization and preventing muscle contraction.
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.
Initial dose 0.4-0.5 mg/kg IV bolus for intubation; maintenance 0.08-0.1 mg/kg IV every 20-45 minutes as needed or continuous infusion 5-10 mcg/kg/min

Terminal half-life: 2-5 hours (prolonged with renal impairment; up to 10 hours in severe impairment)
Terminal elimination half-life: 20-30 minutes (healthy adults). Clinically, recovery is rapid due to redistribution and Hofmann elimination; prolonged in hypothermia or acidosis.
Primarily renal excretion (50-70% unchanged drug), with biliary/fecal elimination (10-20%)
Renal: 10-20% unchanged; biliary/fecal: 50-60% as metabolites and parent drug; Hofmann elimination (non-enzymatic) accounts for ~45% of clearance.
