MOBAN vs PROMAZINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
MOBAN (molindone) is an antipsychotic agent with mechanism of action not fully defined, but believed to involve dopamine D2 receptor blockade in the mesolimbic system, with minimal extrapyramidal effects due to weak D2 binding and possible serotonergic modulation.
Promazine hydrochloride is a phenothiazine antipsychotic that blocks postsynaptic dopamine D2 receptors in the mesolimbic system, as well as histamine H1, alpha-1 adrenergic, and muscarinic cholinergic receptors. It also has moderate serotonin and weak serotonin-dopamine antagonist effects.
Oral: 50-100 mg/day in 3-4 divided doses, increase to 225 mg/day for severe conditions; maximum 400 mg/day. IM: 50-100 mg every 4-6 hours; maximum 400 mg/day.
25-50 mg intramuscularly every 4-6 hours as needed. Maximum 150 mg/day.

Terminal elimination half-life: 6-8 hours for parent drug; active metabolite (molindone) half-life ~12-15 hours; steady-state reached in 2-3 days.
Terminal elimination half-life: 12-18 hours; in elderly or hepatic impairment may extend to 30 hours
Renal: 70-80% as metabolites and unchanged drug; biliary/fecal: ~20%.
Primarily renal (approx. 70-80% as metabolites, <1% unchanged); minor biliary/fecal (approx. 15-20%)
