Valacyclovir Indication

Valacyclovir Pharmacology

Valacyclovir is a prodrug and synthetic purine nucleoside analogue with inhibitory activity against herpes simplex virus types 1 (HSV-1), 2 (HSV-2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), and cytomegalovirus (CMV). Valacyclovir is almost completely converted to acyclovir and L-valine. The inhibitory activity of valacyclovir is highly selective due to its affinity for the enzyme thymidine kinase (TK) encoded by HSV and VZV. This viral enzyme converts acyclovir into acyclovir monophosphate, which is then converted into acyclovir diphosphate and triphosphate by cellular enzymes. Acyclovir is selectively converted to the active triphosphate form by cells infected with herpes viruses.

Valacyclovir Absorption

After oral administration, valacyclovir hydrochloride is rapidly absorbed from the gastrointestinal tract. The absolute bioavailability of acyclovir after administration of valacyclovir is 54.5% ± 9.1%.

Valacyclovir side effects and Toxicity

Adverse effects of overexposure might include headache and nausea.
