Virovir 250Mg (Famciclovir)

Introduction

Virovir 250mg is a medication for treating viral infections that contains Famciclovir, a synthetic purine nucleoside analog used to treat viral illnesses that are caused by the herpesvirus family. Famciclovir has been proven to be beneficial against herpes viruses of types 1 and 2 (HSV-1 and HSV-2), Varicella-zoster virus (VZV), as well as herpes Zoster (shingles).

Virovir can reduce the duration, severity, and frequency of outbreaks by blocking virus replication. It is commonly used to treat cold sores, genital herpes, and shingles. This medication provides those suffering from painful viral attacks.

Composition

• Active Ingredient: Famciclovir 250 mg per tablet
• Excipients: A good mix of fillers, binders, and stabilizers that is suitable for tablet formulation.

Mechanism of Action

Famciclovir is a drug prodrug that is quickly converted by the body into penciclovir, an active antiviral substance. Penciclovir is a selective inhibitor of the DNA polymerase of viral infections, an enzyme vital for the replication of DNA in viral infections. By blocking this enzyme, famciclovir blocks the growth of herpes viruses inside infected cells.

As opposed to some other antivirals, penciclovir is able to prolong the time-to-live within the cell, which allows it to maintain its antiviral effects and efficiency in decreasing viral replication and manifestations.
