pharmachologic effect

The active ingredient of the drug acyclovir is a thymidine nucleoside analogue. Its mechanism of action is that after penetrating an infected cell, the viral enzyme thymidine kinase catalyzes the conversion of acyclovir to acyclovir triphosphate, which is incorporated into the genetic material of the virus (DNA) and interferes with the reading of information (transcription), which leads to blocking of the transcription process (formation and assembly of new viral particles). In healthy, virus-free cells, the enzyme thymidine kinase is absent; therefore, acyclovir does not transform into triphosphate form and does not adversely affect the genetic material of the cell. The virus shows the most activity in relation to the herpes viruses (Herpes simplex) and shingles (Varicella zoster). Less effect, the active ingredient of the drug has on cytomegalovirus and Epstein-Barr virus.
