How Does It Work?
Famciclovir has an inhibitory activity against HSV types 1 (HSV-1) and 2 (HSV-2), varicella-zoster virus (VZV). Thymidine kinase then phosphorylates penciclovir to a monophosphate form, which is then converted to penciclovir triphosphate. This inhibits HSV-2 DNA polymerase by competing with deoxyguanosine triphosphate, thus inhibiting herpes viral DNA synthesis and replication.
Famciclovir is used to treat the following conditions:
- Herpes zoster
- Genital herpes
- Recurrent genital herpes
- Recurrent mucocutaneous herpes in HIV-infected patients
- Recurrent herpes labialis
