How Does It Work?
In vitro and in vivo, Acyclovir displays inhibitory action against human herpesviruses. Acyclovir is converted to acyclovir monophosphate, which is then converted by cellular enzymes to diphosphate and ultimately to triphosphate. After its penetration into the viral DNA, acyclovir triphosphate inhibits viral DNA polymerase and viral DNA replication.
Acyclovir is used to treat the following conditions:
- Infections caused by herpes simplex virus
- Initial and recurrent episodes of genital herpes
- Prophylaxis against herpes simplex infections in individuals with poor immune system
- Treatment of varicella infections (chicken-pox) & herpes zoster (shingles)
- Management of patients with severely compromised immune system, with advanced HIV disease or following bone marrow transplantation
