pharmachologic effect

Antiviral drug. Specifically suppresses in vitro influenza A and B viruses (Influenza virus A, B), including highly pathogenic subtypes A (H1N1) pdm09 and A (H5N1), as well as other viruses that cause ARVI (Coronavirus associated with severe acute respiratory syndrome (SARS), rhinovirus (Rhinovirus), adenovirus (Adenovirus), respiratory syncytial virus (Pneumovirus) and parainfluenza virus (Paramyxovirus)). By the mechanism of antiviral action, it belongs to fusion inhibitors (fusion), interacts with the hemagglutinin of the virus and prevents the fusion of the lipid membrane of the virus and cell membranes. It has a moderate immunomodulatory effect, increases the body's resistance to viral infections. It has interferon-inducing activity - in a study on mice, the induction of interferons was noted after 16 hours,and high titers of interferons remained in the blood up to 48 hours after administration. Stimulates cellular and humoral reactions of immunity: increases the number of lymphocytes in the blood, especially T-cells (CD3), increases the number of T-helpers (CD4), without affecting the level of T-suppressors (CD8), normalizes the immunoregulatory index, stimulates the phagocytic function of macrophages and increases the number of natural killer cells (NK cells). Therapeutic efficacy in viral infections is manifested in a decrease in the duration and severity of the course of the disease and its main symptoms, as well as in a decrease in the incidence of complications associated with a viral infection and exacerbations of chronic bacterial diseases. Refers to low-toxic drugs (LD50> 4 g / kg).Does not have any negative effect on the human body when taken orally in recommended doses.

Absorption and distribution Rapidly absorbed and distributed to organs and tissues. Cmax in blood plasma when taken at a dose of 50 mg is achieved after 1.2 hours, at a dose of 100 mg - after 1.5 hours. Metabolism and excretion Metabolized in the liver. T1 / 2 is 17-21 hours. About 40% is excreted unchanged, mainly with bile (38.9%) and in a small amount by the kidneys (0.12%). During the first day, 90% of the administered dose is excreted.
