Clovir Acyclovir is a synthetic purine derivative which exerts its antiviral effect on herpes simplex virus (HSV) and varicella-zoster virus by interfering with DNA synthesis and inhibiting viral replication. Pharmacologically it is inactive and only becomes activated as a virustatic agent after penetrating into a cell infected by virus. After activation the Acyclovir shows affinity to viral DNA polymerase, and thus selectively inhibits viral DNA polymerase enzyme activity leading to termination of viral DNA chain synthesis.
