  Herpesviruses 2000: Penciclovir
Penciclovir is a nucleoside deoxyguanosine analog that inhibits the DNA synthesis of herpesviruses.

Intravenous penciclovir is not currently licensed as a treatment, but in clinical trials it was found that doses of 5mg per kg every twelve hours was as effective as acyclovir in treating HSV infections.
