MOLINDONE HYDROCHLORIDE vs VESPRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dopamine D2 receptor antagonist; also blocks serotonin 5-HT2A receptors and alpha-adrenergic receptors.
Trifluoperazine is a typical antipsychotic that blocks postsynaptic D2 dopamine receptors in the mesolimbic pathway. It also has alpha-adrenergic blocking and anticholinergic effects.
50-225 mg/day orally in 3-4 divided doses; usual effective dose 50-75 mg/day; maximum 225 mg/day.
10-50 mg intramuscularly every 4-6 hours as needed; oral: 25-50 mg every 4-6 hours

1.5-2 hours; shorter than typical antipsychotics, requiring multiple daily dosing.
Terminal elimination half-life ranges from 1 to 2.5 hours, with a mean of approximately 1.5 hours. Due to its short half-life, multiple daily dosing is required to maintain therapeutic levels, and the drug is rapidly cleared after discontinuation.
Renal: 65-70% as metabolites and unchanged drug; Fecal: 20-25%; Biliary: minor.
Primarily hepatic metabolism with metabolites excreted in urine and feces. Approximately 20-30% of a single dose is excreted unchanged in urine, with the remainder as metabolites in urine (30-40%) and feces (20-30%).
