How Valtrex works?
How the drug acts for herpes is a particularly interesting point. Once in the cells of the body, the active substance Valtrex acyclovir undergoes a series of chemical transformations and becomes the active substance – triphosphate.
Such a transformation is possible only in cells infected with herpes, so that a viral enzyme, thymidine kinase, is necessary for a chemical reaction. This is an amazing property of acyclovir: it acts selectively on virus-infected cells.
Acyclovir stops the growth of the virus DNA. It also blocks the enzyme necessary for copying the virus – DNA polymerase. Moreover, the drug inhibits the viral enzyme ten times stronger than the human.
As a result, treatment of herpes with Valtrex stops the multiplication of the virus, the harmful effect of the infection stops, and the symptoms of herpes pass.
