MOBAN vs PROLIXIN DECANOATE
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.
Fluphenazine decanoate is a long-acting phenothiazine antipsychotic that blocks dopamine D1 and D2 receptors in the brain, particularly in the mesolimbic and mesocortical pathways, with higher affinity for D2 receptors. It also exhibits alpha-adrenergic blocking and anticholinergic activity.
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.
Fluphenazine decanoate initial dose 12.5-25 mg IM or SC every 1-4 weeks; maintenance dose 12.5-50 mg every 2-4 weeks.

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 approximately 14 days (range 6-25 days) after intramuscular injection, reflecting slow release from the oily depot; allows for every 2-4 week dosing.
Renal: 70-80% as metabolites and unchanged drug; biliary/fecal: ~20%.
Renal (approximately 50% as conjugated metabolites, <1% unchanged) and fecal (approximately 30%, primarily via bile).
