APOGEN vs ZOVIRAX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Apocynin is a prodrug that is activated by peroxidases to form dimers that inhibit NADPH oxidase (NOX) enzyme complexes, reducing superoxide production. It also exhibits antioxidant and anti-inflammatory properties.
After intracellular phosphorylation to acyclovir triphosphate, selectively inhibits viral DNA polymerase and incorporates into viral DNA, causing chain termination.
10 mg orally once daily, with or without food.
Herpes simplex: 200 mg orally 5 times daily for 10 days; or 400 mg orally 3 times daily for 5-10 days. Herpes zoster: 800 mg orally 5 times daily for 7-10 days. IV: 5-10 mg/kg every 8 hours for immunocompromised patients with HSV/VZV.

Terminal half-life 3.5 hours; dose adjustment required in renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 2.5-3.3 hours in adults with normal renal function; prolonged to 19.5 hours in anuria (creatinine clearance <10 mL/min).
Renal: 90% unchanged; fecal: 10% as metabolites.
Renal excretion of unchanged drug via glomerular filtration and tubular secretion accounts for 76-82% of elimination; fecal excretion is less than 2%.
