HALDOL SOLUTAB vs NAVANE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Haloperidol is a typical antipsychotic that primarily antagonizes dopamine D2 receptors in the mesolimbic pathway, also blocking alpha-adrenergic, histamine H1, and muscarinic receptors.
Thioxanthene neuroleptic; blocks postsynaptic dopamine D1 and D2 receptors in the brain; also exhibits anticholinergic, alpha-adrenergic blocking, and sedative effects.
1 to 15 mg orally once daily (tablet or orally disintegrating tablet). For acute agitation, 2.5 to 10 mg intramuscularly every 1 to 8 hours. Maximum oral dose: 100 mg/day; maximum IM dose: 20 mg/day.
Oral: 10-20 mg three times daily; maximum 160 mg/day. IM (acute): 5-10 mg every 4-6 hours; maximum 30 mg/day.

Terminal elimination half-life averages 21 hours (range 12-38 hours) in healthy adults; clinically significant for once-daily dosing.
Terminal elimination half-life is approximately 20-24 hours, allowing for once-daily dosing. Steady-state reached in 4-5 days.
Renal (approximately 30-40% as metabolites, <1% unchanged); biliary/fecal (approximately 15-20%); significant enterohepatic recirculation.
Primarily hepatic metabolism; approximately 20-30% excreted renally as metabolites, <1% unchanged. Biliary/fecal excretion accounts for ~50% of metabolites.
