The active substance of the drug acyclovir is an analogue of thymidine nucleoside. Its mechanism of action is that after penetration into the infected cell, the viral enzyme thymidine kinase catalyzes the conversion of acyclovir into acyclovir triphosphate, which is embedded in the genetic material of the virus (DNA) and prevents the reading of information (transcription), which leads to blocking the transcription process (formation and assembly of new virus particles). In healthy cells not infected with the virus, the enzyme thymidine kinase is absent, therefore acyclovir does not become a form of triphosphate and does not adversely affect the genetic material of the cell. The virus shows the greatest activity with respect to herpes simplex viruses (Herpes simplex) and herpes zoster (Varicella zoster). A smaller effect, the active substance of the drug has on cytomegalovirus and the Epstein-Barr virus.
