Famcyclovir
Famciclovir
Famciclovir (pronounced: fam-SYE-klo-veer) is an antiviral medication used to treat infections caused by certain types of viruses. It is a prodrug form of penciclovir with improved oral bioavailability.
Etymology
The name "Famciclovir" is derived from its parent drug, penciclovir. The prefix "Fam-" is an abbreviation of "famciclovir", while "-ciclovir" is a common suffix for antiviral medications.
Usage
Famciclovir is used to treat outbreaks of herpes simplex on the skin (mouth, lips, and genitals), shingles (herpes zoster), and to a lesser extent, for the treatment of chickenpox. It is also used to treat repeat outbreaks of herpes virus cold sores and fever blisters in people with a normal immune system.
Mechanism of Action
Famciclovir is a prodrug that is converted to penciclovir in the body. The conversion process is needed because penciclovir has low oral bioavailability. Once converted, penciclovir works by inhibiting viral DNA replication.
Side Effects
Common side effects of Famciclovir include headache, nausea, and diarrhea. Serious side effects may include anaphylaxis, liver problems, and confusion.
