Mechanism of action

Acyclovir works by selectively inhibiting viral DNA polymerase, which is essential for viral replication. This results in the inhibition of viral DNA synthesis and ultimately, the reduction of viral replication. Acyclovir is a nucleoside analog that is selectively phosphorylated by viral thymidine kinase, which then acts as a prodrug to inhibit viral DNA polymerase.
