Description | Famciclovir, an effective oral prodrug of the antiviral penciclovir, was launched in the UK and shortly after in the U.S.A. for the treatment of shingles (herpes zoster). As the ester of the 6-deoxy- penciclovir, famciclovir has significantly improved oral absorption. It is converted to penciclovir in vivo with a bioavailability of 41 % in rats. Penciclovir is phosphorylated, and hence activated onty in herpesvirus infected cells. This stable metabolite, penciclovir-triphosphate, is a strong inhibitor of herpesvirus DNA polymerases and of viral DNA synthesis with long lasting effects. The high selectivity of famciclovir/penciclovir to herpes family of viruses and their rather low toxicity may make this agent superior to other existing drugs. |
Function | Famciclovir is an antiviral drug. However, Famciclovir is not a cure for these infections. The viruses that cause these infections continue to live in the body even between outbreaks. Famciclovir decreases the severity and length of these outbreaks. Famciclovirhelps the sores heal faster, keeps new sores from forming, and decreases pain/itching. This medication may also help reduce how long pain remains after the sores heal. In addition, in people with a weakened immune system, famciclovir can decrease the risk of the virus spreading to other parts of the body and causing serious infections. |
