MOLINDONE HYDROCHLORIDE vs SPARINE
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.
Phenothiazine antipsychotic; blocks postsynaptic mesolimbic dopaminergic D1 and D2 receptors; also blocks alpha-adrenergic receptors, and has anticholinergic and antihistaminergic effects.
50-225 mg/day orally in 3-4 divided doses; usual effective dose 50-75 mg/day; maximum 225 mg/day.
Promazine hydrochloride: 25-50 mg intramuscularly or intravenously every 4-6 hours as needed; maximum 300 mg/day. Alternatively, oral: 25-200 mg every 4-6 hours; maximum 1000 mg/day. Route and frequency depend on indication and patient response.

1.5-2 hours; shorter than typical antipsychotics, requiring multiple daily dosing.
Terminal elimination half-life: 10-20 hours; clinical context: allows once or twice daily dosing; extended in elderly and hepatic impairment
Renal: 65-70% as metabolites and unchanged drug; Fecal: 20-25%; Biliary: minor.
Primarily renal (70-80% as metabolites, less than 1% unchanged); biliary/fecal (15-30%)
