Valacyclovir is the L-valine ester of acyclovir being thus a prodrug. After absorption into the blood valacyclovir almost completely converted to acyclovir under the influence of hepatic enzyme valacyclovir-hydrolase. In turn Acyclovir formed from valacyclovir affected by the virus penetrates cells where under the influence of the viral enzyme thymidine kinase converted into a monophosphate, then under the influence of cellular kinases - in the active diphosphate and triphosphate. Acyclovir triphosphate inhibits DNA polymerase and thus violates the replication of virus DNA. In addition the violation of the replication of viral DNA may be a result of incorporation of acyclovir into its structure. Thus the high selectivity of valacyclovir for tissues infected with a virus, because the stage I reaction chain phosphorylation mediated by the enzyme produced by the virus.
