PROLIXIN DECANOATE vs TINDAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fluphenazine decanoate is a long-acting phenothiazine antipsychotic that blocks dopamine D1 and D2 receptors in the brain, particularly in the mesolimbic and mesocortical pathways, with higher affinity for D2 receptors. It also exhibits alpha-adrenergic blocking and anticholinergic activity.
TINDAL (trimethoprim) inhibits bacterial dihydrofolate reductase (DHFR), preventing the reduction of dihydrofolate to tetrahydrofolate, thereby inhibiting bacterial DNA synthesis.
Fluphenazine decanoate initial dose 12.5-25 mg IM or SC every 1-4 weeks; maintenance dose 12.5-50 mg every 2-4 weeks.
TINDAL (ticarcillin disodium + clavulanate potassium) 3.1 g (ticarcillin 3 g + clavulanic acid 0.1 g) IV every 4-6 hours. Maximum dose: 18 g ticarcillin/0.6 g clavulanic acid per day.

Terminal elimination half-life approximately 14 days (range 6-25 days) after intramuscular injection, reflecting slow release from the oily depot; allows for every 2-4 week dosing.
Terminal elimination half-life is approximately 12-15 hours in adults with normal renal function; prolonged in renal impairment.
Renal (approximately 50% as conjugated metabolites, <1% unchanged) and fecal (approximately 30%, primarily via bile).
Primarily renal excretion of unchanged drug (70-80%) and hepatic metabolism (20-30%).
