Pharmacological effect
Immunostimulating drug. It has antiviral activity against DNA and RNA genomic viruses. It has a pronounced anti-Chlamydia effect. The activity of the drug is associated with its ability to induce the formation of high titers of endogenous interferons in the body, especially interferon alfa. In V / m, administration of Neovir at a dose of 250 mg for detected serum concentrations of interferon is equivalent to the administration of 6–9 million IU of recombinant interferon alpha. Neovir activates bone stem cells brain, T lymphocytes and macrophages. Shows immunomodulating activity, normalizing the balance between subpopulations of T-helper and T-suppressor cells. In a number of diseases, Neovir is able to reduce the production of tumor necrosis factor in the body (HIV infection, herpes) and activate natural killer cells (in case of tumor diseases). Significantly increases the activity of polymorphonuclear leukocytes. In HIV infection, Neovir has an immunomodulating effect: it increases the absorptive activity of blood serum, increases the ability of leukocytes to synthesize interferon alpha, stimulates the formation of reactive oxygen species by phagocytes. The peak of interferon activity in the blood and tissues is observed several hours after Neovir and lasts for 16-20 hours
Pharmacokinetics
AbsorptionWith i / m administration, the bioavailability of Neovir is more than 90%. After administration of Neovir in a dose of 100-500 mg Cmax in the blood plasma is reached in 15-30 minutes and is 8.3 mcg / ml. After 5 hours, only insignificant concentrations of the active substance are determined, and after 6 hours, the drug is not detected in the blood plasma. After 15-30 minutes after administration of Neovir, serum interferon titers begin to increase in the plasma. Two peaks of interferon plasma levels were detected: 70 IU / ml in 1.5-2 hours and 110 IU / ml in 8-10 hours, after which they begin to decline. After 24 h, the concentration of serum interferon remains quite high, and returns to its original values after 46-48 hours. Metabolism and excretion is not metabolized. T1 / 2 is 1 hour. It is excreted by the kidneys in unchanged form.
