MOBAN vs SONAZINE
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.
Sonazine is an antipsychotic agent that blocks postsynaptic dopamine D2 receptors in the mesolimbic system, with additional antagonist activity at D1, alpha1-adrenergic, histaminergic H1, and muscarinic M1 receptors.
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.
10-20 mg intramuscularly or intravenously every 4-6 hours as needed; maximum 100 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: 24-36 hours; clinical context: allows once-daily dosing, steady state achieved in 5-7 days, prolongation in elderly or hepatic impairment
Renal: 70-80% as metabolites and unchanged drug; biliary/fecal: ~20%.
Renal (70-80% as metabolites, <1% unchanged); fecal (15-20% via biliary elimination)
