Acyclovir is active against herpes simplex virus (Herpes simplex) types 1 and 2, herpes zoster (Varicella zoster), and Epstein-Barr virus. Less sensitive to the effects of acyclovir cytomegalovirus. Molecular biological mechanism of the antiviral activity of acyclovir due to the competitive interaction of the viral thymidine kinase phosphorylation and consistent with the formation of mono-, di-and triphosphate. Acyclovir triphosphate in place of deoxyguanosine incorporated into viral DNA, inhibits DNA polymerase and inhibits the last replication. Herpes acyclovir prevents the formation of new elements of the rash, reduces the likelihood of cutaneous dissemination and visceral complications, promotes the formation of crusts. Helps reduce pain in the acute phase of herpes zoster. Acyclovir for shingles.
When administered independently from the meal, absorbed about 20 % of the acyclovir. Binding to plasma proteins is relatively low ( 9-33 %). Concentration in cerebrospinal fluid is approximately 50 % of the plasma concentration. The maximum concentration is determined by the half-life of 1.5-2 hours acyclovir ingestion of about 4 hours. Mainly kidneys intact, partially (10-15 %) as a metabolite - 9 carboxymethoxy methylguanine. In renal insufficiency, the half-life is greatly increased (up to 19.5 hours). Acyclovir penetrates the blood-brain and placental barriers, excreted in breast milk.
