Medicine Description virustat 200 mg
virustat 200 mg syrup120 ml is a medication that contains acyclovir as its active ingredient. Acyclovir is an antiviral agent that works by inhibiting the replication of viral DNA. It is selectively activated by viral thymidine kinase, converting it into acyclovir monophosphate. This is further phosphorylated to acyclovir triphosphate, which competes with deoxyguanosine triphosphate for incorporation into viral DNA. Once incorporated, acyclovir disrupts the elongation of the DNA strand, effectively terminating further viral replication. This selective action makes it particularly effective against herpes viruses while minimizing effects on host cells.
