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.
Trifluoperazine is a typical antipsychotic of the phenothiazine class. It acts primarily as a dopamine D2 receptor antagonist, blocking postsynaptic dopamine receptors in the mesolimbic and mesocortical pathways. It also exhibits moderate anticholinergic, antiadrenergic, and antihistaminergic activity.
Initial: 2-5 mg orally 3 times daily; maintenance: 15-30 mg orally per day in divided doses; maximum: 60 mg orally per day.
2-10 mg orally twice daily; maximum 40 mg/day. For severe psychosis, 5-20 mg intramuscularly every 4-6 hours, maximum 30 mg/day.

Terminal elimination half-life: 34 hours (range 25–50 hrs) in adults; clinical context: allows once-daily dosing.
12-30 hours (terminal elimination half-life); clinical context: requires multiple daily dosing or extended-release formulations for steady-state maintenance.
Renal: primarily as metabolites, <1% unchanged; fecal: minor; biliary: some metabolites excreted in bile.
Renal (as metabolites, less than 1% unchanged); fecal (biliary) elimination of metabolites accounts for a significant portion; total recovery in urine and feces accounts for >90% of a dose.
