Product description :
Penciclovir is a guanine analogue antiviral drug used for the treatment of various herpesvirus infections. It is a nucleoside analogue which exhibits low toxicity and good selectivity. Because penciclovir is absorbed poorly when given orally (by mouth) it is used more as a topical treatment, and is the active ingredient in the cold sore medications Denavir (NDC 0135-0315-52), Vectavir and Fenistil. Famciclovir is a prodrug of penciclovir with improved oral bioavailability.
