LOXITANE C vs ORAP
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Loxapine, a dibenzoxazepine antipsychotic, acts primarily by blocking dopamine D2 receptors in the brain. It also exhibits affinity for serotonin 5-HT2A receptors, alpha-adrenergic, histaminergic, and muscarinic receptors, contributing to its antipsychotic and sedative effects.
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.
10 mg orally twice daily initially; may increase by 10 mg/day every 3–4 days; usual therapeutic range 60–100 mg/day; maximum 250 mg/day.
Initial: 2 mg orally twice daily; maintenance: 2-10 mg twice daily. Maximum 20 mg/day.

Terminal elimination half-life is 4-8 hours (mean 6 hours). Clinical context: Requires multiple daily dosing; stable plasma levels achieved by second day.
Terminal elimination half-life is 20–40 hours (mean 27 hours). Steady-state achieved in 4–7 days.
