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 depolarization and preventing muscle contraction.
Rocuronium is a nondepolarizing neuromuscular blocking agent that competitively binds to nicotinic acetylcholine receptors at the motor endplate, preventing acetylcholine from inducing muscle contraction.
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
0.6-1.2 mg/kg IV bolus for intubation; maintenance 0.1-0.2 mg/kg IV as needed for neuromuscular blockade.

Terminal elimination half-life: 20-30 minutes (healthy adults). Clinically, recovery is rapid due to redistribution and Hofmann elimination; prolonged in hypothermia or acidosis.
Terminal elimination half-life is approximately 2.3 hours (range 1.7-3.1 hours) in adults with normal renal function. Clinical context: May be prolonged in hepatic or renal impairment.
Renal: 10-20% unchanged; biliary/fecal: 50-60% as metabolites and parent drug; Hofmann elimination (non-enzymatic) accounts for ~45% of clearance.
Primarily renal (70-80% as unchanged drug and metabolites) and biliary (20-30% as unchanged drug and metabolites).
