Valaciclovir is an antiviral prodrug that is rapidly converted in vivo to acyclovir, an agent used primarily for the treatment of herpes simplex virus (HSV) infections and varicella-zoster virus (VZV) infections. It is approved and commonly used today for herpes simplex (genital herpes, cold sores), herpes zoster (shingles), and, sometimes, for cytomegalovirus prophylaxis in transplant patients.
Pharmacokinetic parameters in healthy adult volunteers after a single oral dose of valaciclovir 1000 mg, values reported for acyclovir (active metabolite).
