商品名：Famvir
Antiviral drug. Famciclovir is a synthetic purine analogue (acyclic nucleoside analogue). It is converted to the antiviral drug penciclovir and has antiviral activity against herpes virus type 1 and 2. The action is related to the affinity for the enzyme thymidine kinase (TK), which converts penciclovir into penciclovir triphosphate, which inhibits viral DNA polymerase to prevent DNA chain elongation—thus inhibiting viral DNA chain elongation. It is used for treatment of various forms of herpes virus infection in humans and also has been used for treatment of viral infections in animals. Howev
