VALTOVAL 1GM

About

Valacyclovir is an antiviral drug, a prodrug of acyclovir, specifically designed to treat infections caused by various herpes viruses, including herpes simplex virus (HSV-1 and HSV-2), varicella-zoster virus (VZV), and cytomegalovirus (CMV). Upon oral administration, valacyclovir is rapidly and extensively converted to acyclovir in the body through first-pass metabolism, primarily in the liver and intestine. Acyclovir then acts by inhibiting viral DNA polymerase, thereby preventing viral DNA synthesis and replication without significantly affecting host cell DNA.

This improved bioavailability of valacyclovir compared to acyclovir allows for less frequent dosing, enhancing patient compliance and convenience in managing recurrent outbreaks of genital herpes, cold sores, and shingles. It effectively reduces the duration and severity of these viral episodes and can also be used for suppressive therapy to prevent future recurrences and reduce the risk of transmission. Its targeted action against herpes viruses makes it a valuable therapeutic agent in clinical practice.
