Properties

Valacyclovir is an antiviral agent, is the L-valine ester of acyclovir. Acyclovir is an analogue of the purine nucleotide (guanine).

In humans, valaciclovir is rapidly and almost completely converted to acyclovir and valine, presumably by the enzyme valaciclovir hydrolase.

Aciclovir is a specific inhibitor of herpes viruses with in vitro activity against herpes simplex viruses (HSV) (Herpes simplex) types 1 and 2, varicella-zoster virus (VZV) Varicella zoster, cytomegalovirus (CMV), Epstein-Barr virus (EBV) and virus human herpes type 6. Acyclovir inhibits the synthesis of viral DNA immediately after phosphorylation and conversion into the active form — acyclovir triphosphate.
