CIDOFOVIR vs DENAVIR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cidofovir is a nucleotide analog that inhibits viral DNA polymerase by competing with deoxycytidine triphosphate for incorporation into viral DNA, resulting in chain termination and inhibition of viral replication.
DENAVIR is a synthetic peptide that inhibits viral replication by preventing the fusion of the viral envelope with the host cell membrane. It specifically targets the HIV-1 envelope glycoprotein gp41, blocking the conformational changes required for membrane fusion.
5 mg/kg intravenously once weekly for 2 weeks, then 5 mg/kg every 2 weeks. Administer with probenecid 2 g orally 3 hours before dose, then 1 g at 2 and 8 hours after dose. Hydrate with 1 L normal saline before infusion.
5 mg applied topically to affected area once daily for 4 weeks.

Clinical Note
moderateCidofovir + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Cidofovir."
Clinical Note
moderateTenofovir disoproxil + Cidofovir
"Tenofovir disoproxil may decrease the excretion rate of Cidofovir which could result in a higher serum level."
Terminal elimination half-life is approximately 2.5 hours. However, the intracellular half-life of the active diphosphate metabolite is >48 hours, supporting once-weekly dosing.
Terminal elimination half-life is 2.5–3.5 hours in patients with normal renal function. Prolonged to 20–40 hours in severe renal impairment (CrCl <30 mL/min).
Renal excretion of unchanged drug via glomerular filtration and tubular secretion accounts for approximately 90% of the administered dose. Biliary/fecal elimination is minimal (<5%).
