How Famvir Works
Famvir gets metabolized into an active anti-viral agent called penciclovir by the liver. This compound shows an inhibitory activity against the HSV-1, HSV-2 and VZV (varicella zoster virus). Once the drug is administered, the cells infected with the virus phosporylate penciclovir into mono-phosphate form. This in-turn gets converted into penciclovir tri-phosphate. It is believed that this penciclovir tri-phosphate acts by inhibiting the DNA polymerase of the virus. Consequently, the drug interferes with the DNA synthesis of the virus. Thus Famciclovir selectively inhibits the replication of the DNA in the virus. It reduces the viral growth in the body. Additionally the drug reduces the spread of the virus in the body.
