Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thioridazine is a phenothiazine antipsychotic that blocks postsynaptic mesolimbic dopaminergic D1 and D2 receptors, and also blocks alpha-adrenergic receptors, histamine H1 receptors, and muscarinic M1 receptors.
Thioridazine is a typical antipsychotic that blocks postsynaptic dopamine D2 receptors in the mesolimbic pathway, also exhibiting alpha-adrenergic blockade and anticholinergic effects.
Typical adult dose: 10-25 mg orally 3 times daily. Maximum dose: 200 mg/day.
Initial 50-100 mg orally 3 times daily, titrate to 200-600 mg/day in divided doses; maximum 800 mg/day for severe psychosis.

Terminal elimination half-life 21-24 hours; steady-state achieved within 5-7 days
Terminal elimination half-life: 10–20 hours (mean ~15 hours). Clinical context: Steady-state achieved within 4–5 days; allows once-daily or twice-daily dosing.
Primarily renal (70-80% as metabolites, <1% unchanged); biliary/fecal (20-30%)
Primarily renal (approximately 70%) as metabolites (sulfoxides and glucuronides); about 30% excreted in feces via bile. Less than 1% excreted unchanged.
