HALDOL vs NAVANE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Haloperidol is a typical antipsychotic that blocks dopamine D2 receptors in the central nervous system, particularly in the mesolimbic and mesocortical pathways, reducing positive symptoms of schizophrenia. It also has moderate affinity for sigma receptors and weak affinity for serotonin 5-HT2, alpha-adrenergic, and histamine H1 receptors.
Thioxanthene neuroleptic; blocks postsynaptic dopamine D1 and D2 receptors in the brain; also exhibits anticholinergic, alpha-adrenergic blocking, and sedative effects.
Initial: 1-5 mg PO/IM twice daily; titrate up to 5-10 mg/day. Acute agitation: 5-10 mg IM every 1-8 hours. Maintenance: 5-10 mg/day PO/IM. Maximum: 100 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 is approximately 21 hours (range 12–37 hours). Extended half-life in chronic administration supports once-daily dosing; dose adjustments required in hepatic impairment.
Terminal elimination half-life is approximately 20-24 hours, allowing for once-daily dosing. Steady-state reached in 4-5 days.
Renal (approximately 40%, with 1% unchanged; remainder as metabolites) and fecal (approximately 60%, primarily via bile).
Primarily hepatic metabolism; approximately 20-30% excreted renally as metabolites, <1% unchanged. Biliary/fecal excretion accounts for ~50% of metabolites.
