DENDRID vs GANCICLOVIR
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.
Ganciclovir is a synthetic guanine nucleoside analog that inhibits viral DNA synthesis by competitively inhibiting viral DNA polymerase and by incorporating into viral DNA, causing chain termination. It requires initial phosphorylation by viral thymidine kinase (CMV) or protein kinase (HSV).
1.5 mg/kg IV every 8 hours; typical adult dose 100 mg IV every 8 hours.
Induction: 5 mg/kg IV every 12 hours for 14-21 days. Maintenance: 5 mg/kg IV every 24 hours. Oral: 1000 mg three times daily with food.

Terminal elimination half-life is approximately 3-4 hours in adults with normal renal function; prolonged in renal impairment
Terminal half-life: 2.5-5.0 hours in normal renal function; prolonged to 10-30 hours in renal impairment; requires dose adjustment for CrCl <70 mL/min
Primarily renal excretion; unchanged drug accounts for 70-90% of elimination; minor biliary/fecal excretion (<10%)
Renal excretion: >90% unchanged; biliary/fecal: minimal (<5%)
