MOBAN vs ORAP
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.
Orap (pimozide) is a diphenylbutylpiperidine antipsychotic that selectively blocks dopamine D2 receptors in the central nervous system, with weak antagonism at alpha1-adrenergic and H1-histamine receptors. Its anti-dyskinetic effect in Tourette syndrome may also involve blockade of calcium channels.
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.
Initial: 2 mg orally twice daily; maintenance: 2-10 mg twice daily. Maximum 20 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 is 20–40 hours (mean 27 hours). Steady-state achieved in 4–7 days.
Renal: 70-80% as metabolites and unchanged drug; biliary/fecal: ~20%.
Primarily hepatic metabolism; approximately 40% excreted in urine as metabolites, 15% in feces as unchanged drug and metabolites.
