Pharmacological properties

Pharmacodynamics

Acyclovir is effective against herpes zoster and herpes simplex viruses. Epstein-Barr virus and cytomegalovirus are also susceptible to it. The substance interacts with viral enzymes and prevents their reproduction.

Penetrating into infected cells, acyclovir is converted into acyclovir monophosphate, and then sequentially into acyclovir diphosphate and acyclovir triphosphate. The latter compound significantly inhibits the synthesis of viral DNA, practically without affecting healthy cells.

With herpes, Gerpevir prevents the spread of skin rashes, dries them, accelerating the formation of a crust, reduces the risk of skin dissemination and visceral complications, and reduces the intensity of pain during exacerbation of herpes zoster. Also, the drug is characterized by immunomodulatory properties.

Pharmacokinetics

After oral administration, acyclovir is partially absorbed (approximately 20%). It penetrates well into all tissues and body fluids, including breast milk.

The maximum concentration of the active substance is determined by the dosage. On average, it is registered 90–120 minutes after administration. The half-life is approximately 3 hours, and in the case of renal failure, 19.5 hours.

Acyclovir is excreted mainly in the urine unchanged. With increasing age of the patient, the time for elimination of this substance from the body increases.

When applied topically, acyclovir practically does not penetrate the systemic circulation and has a slight systemic effect. When the drug is applied to the affected area of the skin, a therapeutic concentration of the active substance is created on it, providing a therapeutic effect for at least 5 hours.
