What drug class is famciclovir?
Famciclovir is an antiviral medication in the nucleoside analogue class, specifically used as a guanosine (purine) nucleoside analogue. Once inside the body, it is converted to penciclovir, which then inhibits viral DNA replication.
What viruses is famciclovir used against?
Famciclovir is used for herpesvirus infections, including herpes simplex virus (HSV) infections (such as cold sores and genital herpes) and herpes zoster (shingles). It acts against virus replication after infection, helping shorten illness and reduce symptom duration when started early.
Is famciclovir similar to valacyclovir or acyclovir?
Famciclovir, valacyclovir, and acyclovir are all used to treat herpesvirus infections and fall within the broader category of antiviral therapies that inhibit viral DNA synthesis. Famciclovir and valacyclovir are prodrugs designed to improve oral absorption compared with acyclovir, but they convert into different active antiviral compounds (famciclovir converts to penciclovir).
