RIMANTADINE HYDROCHLORIDE vs TRIFLURIDINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Rimantadine is a tricyclic amine antiviral that inhibits influenza A virus replication by blocking the M2 proton ion channel, preventing viral uncoating and release of viral RNA into host cells.
Trifluridine is a thymidine analog that inhibits thymidylate synthase and incorporates into DNA, leading to DNA damage and cell death.
100 mg orally twice daily for 7 days; initiate within 48 hours of symptom onset.
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%.

"Trifluridine may decrease the cardiotoxic activities of Acetyldigitoxin."
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.
Renal: 75% unchanged; fecal: <10%; biliary: minimal. Total clearance 2.5 mL/min/kg.
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.
