How does Acyclovir / Generic Zovirax work?
Acyclovir is a guanosine analogue antiviral drug, which has inhibitory activity against the herpes virus. Zovirax has a high affinity for the enzyme thymidine kinase. This enzyme helps in converting Acyclovir into Acyclovir monophosphate, which is further converted to diphosphate and triphospahte. By inhibiting the viral DNA polymerase, Zovirax in the triphosphate form stops the replication of the viral DNA. As the virus is prevented from multiplying, the infection also reduces in its severity and also prevents it from spreading further.
