Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dopamine D2 receptor antagonist; also blocks serotonin 5-HT2A receptors and alpha-adrenergic receptors.
Promazine hydrochloride is a phenothiazine antipsychotic that blocks postsynaptic dopamine D2 receptors in the mesolimbic system, as well as histamine H1, alpha-1 adrenergic, and muscarinic cholinergic receptors. It also has moderate serotonin and weak serotonin-dopamine antagonist effects.
50-225 mg/day orally in 3-4 divided doses; usual effective dose 50-75 mg/day; maximum 225 mg/day.
25-50 mg intramuscularly every 4-6 hours as needed. Maximum 150 mg/day.

1.5-2 hours; shorter than typical antipsychotics, requiring multiple daily dosing.
Terminal elimination half-life: 12-18 hours; in elderly or hepatic impairment may extend to 30 hours
Renal: 65-70% as metabolites and unchanged drug; Fecal: 20-25%; Biliary: minor.
Primarily renal (approx. 70-80% as metabolites, <1% unchanged); minor biliary/fecal (approx. 15-20%)
