NAVANE vs PROLIXIN ENANTHATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thioxanthene neuroleptic; blocks postsynaptic dopamine D1 and D2 receptors in the brain; also exhibits anticholinergic, alpha-adrenergic blocking, and sedative effects.
Fluphenazine (the active entity of PROLIXIN ENANTHATE) is a phenothiazine antipsychotic that blocks postsynaptic dopamine D1 and D2 receptors in the mesolimbic and mesocortical pathways. It also exhibits alpha-adrenergic blocking and anticholinergic effects.
Oral: 10-20 mg three times daily; maximum 160 mg/day. IM (acute): 5-10 mg every 4-6 hours; maximum 30 mg/day.
12.5-50 mg intramuscularly every 1-3 weeks. Initial dose: 2.5-12.5 mg IM as a test dose; gradual titration based on response and tolerability.

Terminal elimination half-life is approximately 20-24 hours, allowing for once-daily dosing. Steady-state reached in 4-5 days.
Terminal elimination half-life approximately 11-15 days due to slow release from intramuscular depot; requires monitoring for prolonged effects after discontinuation
Primarily hepatic metabolism; approximately 20-30% excreted renally as metabolites, <1% unchanged. Biliary/fecal excretion accounts for ~50% of metabolites.
Primarily renal (30-40% as metabolites, <1% unchanged) and biliary/fecal (15-20%)
