Antiviral drug – a synthetic analog of a nucleoside of thymidine. In the infected cells containing a virus thymidinekinase there is a phosphorylation and transformation into active connection – an acyclovir triphosphate. Sharp selectivity of action and a hypotoxicity for the person are caused by lack of necessary enzyme for its activation in intact cells of a macroorganism. An acyclovir triphosphate, "being built in" in synthesized by the DNA virus, blocks reproduction of a virus. Specificity and very high selectivity of action is also caused by its preferential accumulation in the cells affected with a herpes virus.
