DENDRID vs GANCICLOVIR SODIUM
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 derivative that inhibits viral DNA synthesis. It is phosphorylated to ganciclovir triphosphate by viral thymidine kinase (CMV UL97 gene product) and cellular kinases. Ganciclovir triphosphate competitively inhibits viral DNA polymerase (CMV UL54 gene product) and incorporates into viral DNA, causing chain termination.
1.5 mg/kg IV every 8 hours; typical adult dose 100 mg IV every 8 hours.
5 mg/kg IV every 12 hours for 14-21 days for induction; 5 mg/kg IV once daily or 6 mg/kg IV once daily 5 days per week for maintenance. Oral ganciclovir not available as sodium salt.

Terminal elimination half-life is approximately 3-4 hours in adults with normal renal function; prolonged in renal impairment
Terminal half-life: 2.5-3.6 hours in normal renal function; prolonged in renal impairment (up to 30 hours in severe cases). Dosage adjustment required for CrCl <80 mL/min.
Primarily renal excretion; unchanged drug accounts for 70-90% of elimination; minor biliary/fecal excretion (<10%)
Renal: >90% unchanged drug via glomerular filtration and tubular secretion. Biliary/fecal: <1%.
