MELLARIL vs ZUMANDIMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thioridazine is a phenothiazine antipsychotic that blocks postsynaptic mesolimbic dopaminergic D1 and D2 receptors, and also blocks alpha-adrenergic receptors, histamine H1 receptors, and muscarinic M1 receptors.
ZUMANDIMINE is a selective norepinephrine reuptake inhibitor that increases synaptic norepinephrine levels, enhancing adrenergic signaling in the CNS and peripheral nervous system.
Typical adult dose: 10-25 mg orally 3 times daily. Maximum dose: 200 mg/day.
The typical adult dose of ZUMANDIMINE is 250 mg intravenously every 12 hours infused over 60 minutes.

Terminal elimination half-life 21-24 hours; steady-state achieved within 5-7 days
Terminal elimination half-life is 12-15 hours in healthy adults (range 10-18 hours). In moderate renal impairment (CrCl 30-50 mL/min), half-life prolongs to 20-28 hours; in severe hepatic impairment (Child-Pugh C), half-life extends to 24-35 hours. This supports twice-daily dosing in normal renal function and requires dose adjustment in renal or hepatic impairment.
Primarily renal (70-80% as metabolites, <1% unchanged); biliary/fecal (20-30%)
Renal excretion accounts for 65% of elimination (primarily as unchanged drug via glomerular filtration and tubular secretion), biliary/fecal excretion accounts for 30% (with enterohepatic recycling of metabolites), and 5% is metabolized via CYP3A4 with subsequent excretion. The cumulative urinary recovery of unchanged drug is 60-70% within 48 hours.
