THIOTHIXENE vs THORAZINE
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 brain. It also has alpha-adrenergic and histamine H1 blocking activity, with minimal anticholinergic effects.
Antagonist at dopamine D2 receptors in the mesolimbic pathway; also blocks alpha-adrenergic, histaminergic, and muscarinic receptors.
Initial: 2 mg orally three times daily; maintenance: 5-30 mg/day orally in divided doses; maximum: 60 mg/day. IM: 4 mg 2-4 times daily; maximum 30 mg/day.
10-25 mg orally 3-4 times daily; maximum 800 mg/day. 25-50 mg intramuscularly every 4-6 hours.

Terminal half-life: 10-20 hours (mean ~14 h). Clinical context: Steady-state achieved in ~2-3 days; allows once-daily dosing for maintenance.
Clinical Note
moderateThiothixene + Deferasirox
"The serum concentration of Deferasirox can be increased when it is combined with Thiothixene."
Clinical Note
moderateThiothixene + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Thiothixene is combined with Fluticasone propionate."
Clinical Note
moderateThiothixene + Tenofovir disoproxil
"The metabolism of Tenofovir disoproxil can be decreased when combined with Thiothixene."
Clinical Note
moderateTerminal elimination half-life: 15–30 hours (mean ~24 h); may extend to 40+ h in elderly or hepatic impairment.
Primarily renal: 65-70% as metabolites, <1% unchanged. Fecal: 15-20% via biliary elimination.
Renal (biliary/fecal): ~70% renal as metabolites, ~30% biliary/fecal; <1% unchanged in urine.
