HERPERAX 800 TAB

About

Herperax 800 mg, containing Acyclovir, is a potent antiviral agent specifically formulated to combat infections caused by the herpes simplex virus (HSV) and varicella-zoster virus (VZV). Its sophisticated mechanism of action involves selective phosphorylation by viral thymidine kinase, an enzyme predominantly expressed in virally infected cells, which converts acyclovir into its active triphosphate form. This active metabolite then acts as a competitive inhibitor of viral DNA polymerase and is incorporated into the viral DNA, leading to premature chain termination and irreversible inactivation of the viral enzyme. This targeted action ensures high efficacy against herpesviruses while minimizing adverse effects on host cellular processes. The 800 mg dosage is frequently employed for more severe or established infections, particularly in the treatment of herpes zoster (shingles), where it helps to reduce pain, accelerate lesion healing, and prevent post-herpetic neuralgia. It is also used for the management of severe initial or recurrent genital herpes episodes.
