DENDRID vs INCIVEK
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.
Inhibitor of the HCV NS3/4A serine protease, preventing cleavage of the HCV polyprotein, thereby inhibiting viral replication.
1.5 mg/kg IV every 8 hours; typical adult dose 100 mg IV every 8 hours.
Incivek (telaprevir) is administered orally at a dose of 750 mg (two 375 mg tablets) three times daily (every 7-9 hours) with food (not low-fat).

Terminal elimination half-life is approximately 3-4 hours in adults with normal renal function; prolonged in renal impairment
Terminal elimination half-life ranges from 4 to 13 hours (mean ~7 hours) in healthy volunteers; prolonged to 10-20 hours in HCV-infected patients.
Primarily renal excretion; unchanged drug accounts for 70-90% of elimination; minor biliary/fecal excretion (<10%)
Approximately 91% of the radiolabeled dose is recovered in feces (79% as unchanged drug) and 9% in urine (1% as unchanged drug).
