ADASUVE vs MOLINDONE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Loxapine (the active ingredient in ADASUVE) is a dibenzoxazepine antipsychotic agent that acts primarily as a dopamine D2 receptor antagonist. It also exhibits affinity for serotonin 5-HT2A, 5-HT2C, and histamine H1 receptors, and to a lesser extent, alpha-adrenergic and muscarinic receptors. The exact mechanism of its antipsychotic effect is thought to involve dopamine and serotonin receptor blockade.
Dopamine D2 receptor antagonist; also blocks serotonin 5-HT2A receptors and alpha-adrenergic receptors.
Inhalation: 10 mg as a single dose via oral inhalation up to a maximum of 2 doses within a 24-hour period, each dose separated by at least 2 hours. For agitation associated with schizophrenia or bipolar I disorder.
50-225 mg/day orally in 3-4 divided doses; usual effective dose 50-75 mg/day; maximum 225 mg/day.

Mean terminal half-life of loxapine is 6-8 hours; active metabolite 7-hydroxyloxapine (amoxapine) has half-life of ~30 hours. Clinically, steady state achieved within 3-5 days.
1.5-2 hours; shorter than typical antipsychotics, requiring multiple daily dosing.
Primarily renal (30-40% as unchanged drug and metabolites; ~50% as loxapine metabolites), with minor biliary/fecal elimination (<10%).
Renal: 65-70% as metabolites and unchanged drug; Fecal: 20-25%; Biliary: minor.
