DENDRID vs TRIFLURIDINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dendrid (idoxuridine) is a pyrimidine nucleoside analog that inhibits viral DNA replication by incorporating into viral DNA and inhibiting thymidylate synthetase, thereby blocking DNA synthesis.
Trifluridine is a thymidine analog that inhibits thymidylate synthase and incorporates into DNA, leading to DNA damage and cell death.
1.5 mg/kg IV every 8 hours; typical adult dose 100 mg IV every 8 hours.
Topical: Apply one drop to affected eye every 2 hours while awake (maximum 9 drops/day) until re-epithelialization, then one drop every 4 hours for 7 days. Ophthalmic solution 1%.

Terminal elimination half-life is approximately 3-4 hours in adults with normal renal function; prolonged in renal impairment

The terminal elimination half-life of trifluridine is approximately 12-18 hours. This prolonged half-life supports twice-daily dosing and provides sustained exposure for antiviral activity.
Primarily renal excretion; unchanged drug accounts for 70-90% of elimination; minor biliary/fecal excretion (<10%)
Renal excretion accounts for approximately 40-50% of the administered dose, primarily as the inactive metabolite 5-trifluorothymidine. Fecal excretion is minimal (<5%). The remainder is eliminated via metabolic degradation.
