Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiothixene is a typical antipsychotic that blocks postsynaptic dopamine D1 and D2 receptors in the central nervous system, particularly in the mesolimbic and mesocortical pathways. It also has affinity for serotonin 5-HT2, histamine H1, and alpha-1 adrenergic receptors, contributing to its therapeutic and adverse 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 mg orally three times daily. Maintenance: 15-30 mg orally daily in divided doses. Maximum: 60 mg/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 ranges from 26 to 36 hours in healthy adults, allowing for once-daily dosing in maintenance therapy. In chronic use, the half-life may be prolonged due to accumulation.
12-30 hours (terminal elimination half-life); clinical context: requires multiple daily dosing or extended-release formulations for steady-state maintenance.
Primarily renal and biliary; about 50-60% of a single dose is excreted in the urine as metabolites and unchanged drug within 48 hours, with approximately 30-40% eliminated in feces via biliary secretion. Less than 1% of the parent drug is excreted unchanged in urine.
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.
