NAVANE vs ORAP
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thioxanthene neuroleptic; blocks postsynaptic dopamine D1 and D2 receptors in the brain; also exhibits anticholinergic, alpha-adrenergic blocking, 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.
Oral: 10-20 mg three times daily; maximum 160 mg/day. IM (acute): 5-10 mg every 4-6 hours; maximum 30 mg/day.
Initial: 2 mg orally twice daily; maintenance: 2-10 mg twice daily. Maximum 20 mg/day.

Terminal elimination half-life is approximately 20-24 hours, allowing for once-daily dosing. Steady-state reached in 4-5 days.
Terminal elimination half-life is 20–40 hours (mean 27 hours). Steady-state achieved in 4–7 days.
Primarily hepatic metabolism; approximately 20-30% excreted renally as metabolites, <1% unchanged. Biliary/fecal excretion accounts for ~50% of metabolites.
