Cuvir is indicated for the treatment of Herpes simplex keratitis.
Acyclovir is an antiviral agent which is highly active in vitro against Herpes simplex (HSV) types I and II and Varicella zoster viruses, but its toxicity to mammalian cells is low. Acyclovir is phosphorylated to the active compound Acyclovir triphosphate after entry into herpes infected cell. The first step in this process requires the presence of the viral-coded thymidine kinase. Acyclovir triphosphate acts as an inhibitor of and substrate for the herpes specified DNA polymerase preventing further viral DNA synthesis without affecting normal cellular processes.
