Valtrex or Valacyclovir is an antiviral drug. It is a prodrug that through metabolisation is converted into acyclovir. Bioavailability after Valacyclovir hepatic first pass metabolisation reaches 55% unlike when using normal acyclovir only 10-11%. After Acyclovir reaches the virus infested cell it is converted into aciclo-GTP that later incorporates into the viral DNA, thus resulting in chain termination and unavailability for the virus to replicate. The overall effect of Valtrex is slowing growth and spread of the virus so that the body can fight it normally. It does not cure the virus completely but it eases the symptoms of the infection.
