METOCURINE IODIDE vs MIVACURIUM CHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive nicotinic acetylcholine receptor antagonist at the neuromuscular junction, blocking acetylcholine binding and preventing muscle contraction.
Mivacurium chloride is a non-depolarizing neuromuscular blocking agent that competitively binds to nicotinic acetylcholine receptors at the motor end-plate, preventing acetylcholine from binding and thereby inhibiting neuromuscular transmission. It is a mixture of stereoisomers and is rapidly hydrolyzed by plasma cholinesterase.
Initial dose 0.2 mg/kg IV; maintenance doses of 0.1-0.15 mg/kg IV as needed for neuromuscular blockade.
0.15-0.25 mg/kg IV bolus for endotracheal intubation; maintenance infusion: 0.5-1.5 mcg/kg/min IV

Terminal elimination half-life: 3-5 hours in patients with normal renal function. Prolonged in renal impairment.
Terminal elimination half-life is approximately 2 minutes (range 1-3 minutes) for the initial rapid distribution phase, and the elimination half-life is about 17-20 minutes in patients with normal renal function. Clinically, this short half-life allows for rapid recovery of neuromuscular function.
Renal: 85-90% unchanged; biliary/fecal: <5%.
Primarily renal excretion of unchanged drug and metabolites; approximately 90-95% eliminated via urine, with less than 5% in feces. Minor biliary excretion.
