CHLORPROMAZINE HYDROCHLORIDE INTENSOL vs PERMITIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorpromazine is a phenothiazine antipsychotic that blocks postsynaptic dopamine D2 receptors in the central nervous system, particularly in the mesolimbic and mesocortical pathways. It also exhibits antagonism at serotonin 5-HT2, histamine H1, alpha-1 adrenergic, and muscarinic receptors, contributing to its sedative, antiemetic, and hypotensive effects.
Antagonist at dopamine D2 receptors, also blocks alpha-1 adrenergic, histaminergic, and muscarinic receptors.
Oral: 25-50 mg 2-3 times daily, up to 1000 mg/day in severe psychosis. IM: 25-50 mg every 1-4 hours until controlled, then switch to oral.
2.5-10 mg orally every 8-12 hours; maximum 40 mg/day. For severe psychosis: initial 10 mg IM, then 5-10 mg IM every 6-8 hours; maximum 30 mg/day IM.

15-30 hours; prolonged in elderly and hepatic impairment; active metabolites (e.g., 7-hydroxychlorpromazine) have longer half-lives (up to 12-24 hours)
Terminal elimination half-life: 20-30 hours; clinically, steady-state achieved in 5-7 days; prolonged in elderly and hepatic impairment
Renal (70-80% as metabolites, <1% unchanged); biliary/fecal (~20-30%)
Renal: <1% unchanged; Hepatic: extensively metabolized, metabolites excreted in urine (50-60%) and feces (30-40%)
