Pharmacological properties

Antiviral drug.

Specifically suppresses in vitro influenza viruses A and B (Influenza virus A, B), including highly pathogenic subtypes A(H1N1)pdm09 and A(H5N1), as well as others viruses - causative agents of SARS (coronavirus (Coronavirus), associated with severe acute respiratory syndrome (SARS), rhinovirus (Rhinovirus), adenovirus (Adenovirus), respiratory syncytial virus (Pneumovirus) and parainfluenza virus (Paramyxovirus)).

According to the mechanism of antiviral action, it belongs to fusion inhibitors (fusion), interacts with 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 persisted in the blood until 48 hours after administration.

Stimulates cellular and humoral immune responses: 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 immunoregulatory index, stimulates the phagocytic function of macrophages and increases the number of natural killers (NK-cells).

Therapeutic effectiveness in viral infections is manifested in reducing the duration and severity of the course of the disease and its main symptoms, as well as in reducing the incidence of complications associated with viral infection and exacerbations of chronic bacterial diseases.

Refers to low-toxic drugs (LD ₅₀ >4 g/kg). Does not have any negative effect on the human body when administered orally at recommended doses.
