LOXAPINE SUCCINATE vs MOBAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Loxapine is a dibenzoxazepine antipsychotic that exerts its effects primarily through antagonism of dopamine D2 and serotonin 5-HT2A receptors. It also has moderate affinity for histamine H1, alpha-1 adrenergic, and muscarinic acetylcholine receptors.
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.
Initial: 10 mg twice daily orally; increase to 25-50 mg twice daily over 7-10 days; maximum 250 mg/day. IM: 12.5-50 mg every 4-6 hours.
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.

Terminal elimination half-life: 12–19 hours (mean 16 hours) after oral administration; steady-state reached within 3–5 days.
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.
Renal (approximately 60% as metabolites, <1% unchanged) and fecal (approximately 40% as metabolites).
Renal: 70-80% as metabolites and unchanged drug; biliary/fecal: ~20%.
