FLUOTREX vs POKONZA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
The active metabolite of FLUOTREX, 5-fluorouracil (5-FU), inhibits thymidylate synthase, leading to depletion of thymidine triphosphate and inhibition of DNA synthesis. Additionally, it incorporates into RNA, disrupting RNA function.
POKONZA (ponazuril) is a triazine antiprotozoal agent that inhibits the mitochondrial electron transport chain at the cytochrome bc1 complex, disrupting the parasite's energy metabolism and leading to its death. It is active against apicomplexan parasites such as Toxoplasma gondii, Neospora caninum, and Sarcocystis neurona.
20 mg/m2 intramuscularly once weekly, not to exceed 30 mg/m2 per week.
Intravenous: 0.1 mg/kg every 8 hours for 28 consecutive days per 6-week cycle.

Terminal elimination half-life is approximately 3-5 hours in adults with normal renal function. In patients with renal impairment, half-life may be prolonged up to 10-15 hours, necessitating dose adjustment.
Terminal elimination half-life 12-15 hours; clinically significant for once-daily dosing with steady-state achieved in 3-5 days
Primarily renal excretion as unchanged drug (approximately 60-70% of administered dose), with the remainder eliminated via biliary/fecal routes (20-30%) and minor metabolic clearance.
Primarily renal excretion (70-80% unchanged drug); biliary/fecal elimination accounts for 15-20%
