THIOTHIXENE HYDROCHLORIDE vs THORAZINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiothixene hydrochloride is a typical antipsychotic that blocks postsynaptic dopamine D2 receptors in the central nervous system (CNS), particularly in the mesolimbic and mesocortical pathways. It also has alpha-adrenergic blocking activity and weak anticholinergic effects.
Antagonist at dopamine D2 receptors in the mesolimbic pathway; also blocks alpha-adrenergic, histaminergic, and muscarinic receptors.
Initial: 2-5 mg orally 3 times daily; maintenance: 15-30 mg orally per day in divided doses; maximum: 60 mg orally per day.
10-25 mg orally 3-4 times daily; maximum 800 mg/day. 25-50 mg intramuscularly every 4-6 hours.

Terminal elimination half-life: 34 hours (range 25–50 hrs) in adults; clinical context: allows once-daily dosing.
Terminal elimination half-life: 15–30 hours (mean ~24 h); may extend to 40+ h in elderly or hepatic impairment.
Renal: primarily as metabolites, <1% unchanged; fecal: minor; biliary: some metabolites excreted in bile.
Renal (biliary/fecal): ~70% renal as metabolites, ~30% biliary/fecal; <1% unchanged in urine.
