Biochem/physiol Actions

Famciclovir is an Antiviral; Guanine analog used to treat herpesvirus infections.

Famciclovir is an antiretroviral guanosine analog used to treat herpesvirus infections and hepatitis B. Famciclovir is rapidly converted to penciclovir. Viral thymidine kinase phosphorylates penciclovir to a monophosphate form that celular kinases convert in turn to penciclovir triphosphate. Penciclovir triphosphate competitively inhibits viral DNA polymerase and thus viral replication. Prolonged administration can lead to resistance; it is often manifested as selection of pre-existing resistant strains with mutations in the reverse transcriptase domain of the DNA polymerase gene.
