GANCICLOVIR vs HEPSERA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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).
Acyclic nucleotide analog of adenosine monophosphate; inhibits hepatitis B virus (HBV) DNA polymerase by competing with the natural substrate dATP, causing DNA chain termination after incorporation into viral DNA.
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.
10 mg orally once daily.

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
Terminal elimination half-life is approximately 6-9 hours in patients with normal renal function. In renal impairment, half-life is prolonged (up to 18 hours in moderate impairment, >30 hours in severe impairment). Steady-state is achieved within 5-7 days.
Renal excretion: >90% unchanged; biliary/fecal: minimal (<5%)
Primarily renal; 70-90% of an oral dose is excreted unchanged in urine via active tubular secretion and glomerular filtration. Biliary/fecal elimination accounts for <5%.
