Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antipsychotic that blocks postsynaptic dopamine D2 receptors in the mesolimbic system; also exhibits anticholinergic, alpha-adrenergic blocking, and extrapyramidal effects.
Thioxanthene antipsychotic; blocks postsynaptic dopamine D1 and D2 receptors in the mesolimbic system; also has anticholinergic, antihistaminergic, and alpha-adrenergic blocking effects.
2.5-10 mg orally divided every 6-8 hours initially; maintenance 1-5 mg orally daily. For severe psychoses, 2.5-10 mg intramuscularly every 6-8 hours. Maximum oral dose 40 mg/day.
Oral: 25-50 mg three times daily, increased as needed to 400-600 mg/day. IM: 12.5-25 mg every 6-8 hours.

Terminal elimination half-life 14-24 hours after oral administration; may be longer (up to 48 hours) with chronic use due to accumulation in deep tissues. Clinically, steady state is achieved in 4-7 days.
Terminal elimination half-life is approximately 20-40 hours (mean 30 hours). Steady-state reached in 5-7 days.
Primarily renal (approximately 50-60% as metabolites, <1% unchanged); fecal (30-40% via biliary elimination); small amount excreted in breast milk.
Primarily hepatic metabolism; <1% excreted unchanged in urine. Metabolites eliminated renally (30%) and fecally (70%).
