Valacyclovir-d₈ (hydrochloride) is the deuterium labeled Valacyclovir hydrochloride. Valacyclovir hydrochloride (Valaciclovir hydrochloride) is an orally active antiviral agent for herpes simplex, herpes zoster, and herpes B. Valacyclovir hydrochloride inhibits HSV-1 W (50=2.9 μg/ml). Valacyclovir hydrochloride is a proagent of Aciclovir (HY-17422) [4][5].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs.
