ANECTINE vs MIVACURIUM CHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Depolarizing neuromuscular blocker; mimics acetylcholine at nicotinic receptors at the neuromuscular junction, causing sustained depolarization and receptor desensitization.
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.
1-1.5 mg/kg IV bolus for intubation; maintenance infusion: 2.5-4.3 mg/min IV; alternatively, 3-4 mg/kg IM for intubation.
0.15-0.25 mg/kg IV bolus for endotracheal intubation; maintenance infusion: 0.5-1.5 mcg/kg/min IV

2-5 minutes (pseudocholinesterase hydrolysis); terminal half-life of succinylmonocholine ~30-60 minutes; clinical duration of apnea determined by rapid initial hydrolysis
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: 10-15% unchanged; hepatic: rapid hydrolysis by plasma pseudocholinesterase (butyrylcholinesterase) to succinylmonocholine and succinic acid; <2% biliary; <2% fecal
Primarily renal excretion of unchanged drug and metabolites; approximately 90-95% eliminated via urine, with less than 5% in feces. Minor biliary excretion.
