Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist at nicotinic acetylcholine receptors at the neuromuscular junction, preventing acetylcholine binding and causing skeletal muscle relaxation.
Competitive antagonist at nicotinic acetylcholine receptors at the neuromuscular junction, preventing acetylcholine-mediated depolarization and muscle contraction.
0.4–0.5 mg/kg IV bolus for intubation; maintenance: 0.08–0.1 mg/kg IV as needed or infusion 5–10 mcg/kg/min
Initial IV bolus of 0.15-0.2 mg/kg (following succinylcholine) or 0.25 mg/kg (without succinylcholine) over 30-60 seconds. Maintenance infusion: 8-10 mcg/kg/min for continuous neuromuscular blockade during anesthesia.

Terminal elimination half-life is approximately 20 minutes (range 15-25 min) in healthy adults. Clinical context: Recovery from neuromuscular blockade is faster than for nondepolarizing relaxants cleared renally. Half-life may be prolonged in hypothermia or acidosis but is minimally affected by renal or hepatic impairment.
Terminal elimination half-life is approximately 2-3 minutes (0.03-0.05 h) due to rapid hydrolysis by plasma esterases; clinical duration is short, with recovery of neuromuscular function beginning within 5-10 minutes after bolus dose.
Renal (50-60% unchanged), biliary/fecal (20-30% as metabolites, mainly laudanosine), and Hofmann elimination (non-enzymatic, pH- and temperature-dependent) accounts for approximately 40-50% of clearance.
Renal excretion of unchanged drug and metabolites accounts for approximately 50% of the dose; biliary/fecal elimination accounts for the remainder, primarily as metabolites via the liver.
