LOXITANE IM vs MOBAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LOXITANE IM (loxapine) is a dibenzoxazepine antipsychotic. Its mechanism of action is not fully established but is thought to be mediated via antagonism of central dopamine D2 and serotonin 5-HT2A receptors. It has high affinity for D2, D3, D4, and 5-HT2A receptors and low affinity for D1 receptors. It also has moderate affinity for histamine H1 and alpha1-adrenergic 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.
Adults: 12.5-50 mg IM every 4-6 hours as needed, not to exceed 150 mg/day.
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: 8-12 hours. Clinically, steady-state reached in 2-3 days; dosing interval based on q6-12h.
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.
Primarily renal: 70% as metabolites; biliary/fecal: 30% as metabolites and unchanged drug.
Renal: 70-80% as metabolites and unchanged drug; biliary/fecal: ~20%.
