Information about Acyclovir
Acyclovir is a nucleoside analogue and antiviral agent used in therapy of herpes and varicella-zoster virus infections.
Liver safety of Acyclovir
Acyclovir has not been associated with clinically apparent liver injury.
Mechanism of action of Acyclovir
Acyclovir (ay sye' kloe vir) is an acyclic purine nucleoside analogue (acycloguanosine) which has antiviral activity against many herpes viruses, including herpes simplex 1 and 2, cytomegalovirus, Ebstein-Barr virus and varicella-zoster. Acyclovir is phosphorylated intracellularly by viral kinases, and the resultant triphosphate competes with guanosine for incorporation into viral DNA blocking viral DNA polymerase activity.
Clinical use of Acyclovir
FDA approval information for Acyclovir
Acyclovir was approved for use in herpes virus infections in the United States in 1982, and is still widely used in treatment and prophylaxis of genital and mucocutaneous herpes simplex infection with almost 5 million prescriptions filled yearly.

Acyclovir is available as capsules of 200 mg, tablets of 400 and 800 mg, oral suspensions, creams, ointments, and parenteral preparations in several generic forms, as well as under the brand name of Zovirax.
