Antiviral drug. Acyclovir is a synthetic purine analogue (acyclic nucleoside analogue). It has antiviral activity against herpes virus. The action is related to the affinity for the enzyme thymidine kinase (TK). However, resistance among some virus forms is possible because of changes in TK or in the DNA polymerase. It is used for treatment of various forms of herpes virus infection in humans and also has been used for treatment of viral infections in animals. However, feline herpes virus 1 (FHV1) is resistant to acyclovir and valciclovir, and studies are lacking on the susceptibility of other
Acyclovir is an antiviral drug. The use in veterinary medicine is limited because the activity against some viruses (e.g., FHV1) is either poor or unknown. In cats, acyclovir had poor absorption and produced toxicity. Acyclovir is able to inhibit replication of equine herpes virus (EHV1) in vitro. However, acyclovir oral absorption in horses was poor and inconsistent and intravenous treatment is needed for treatment of EHV1 infection.
