   <(In.): Aciclovir, acyclovir: chemical name acycloguanosine, is a guanine analogue antiviral drug, marketed under trade names such as Zovirax and Zovir. One of the most commonly-used antiviral drugs, it is primarily used for the treatment of herpes simplex virus infections, as well as in the treatment of herpes zoster. Acyclovir was seen as the start of a new era in antiviral therapy, as it is extremely selective and low in cytotoxicity. Pharmacologist Gertrude B. Elion was awarded the 1988 Nobel Prize in Medicine, partly for the development of acyclovir.
