Pharmacodynamics Arbidol:
ARBIDOL Antiviral agent.
Specifically inhibits in vitro influenza A and B viruses (Influenzavirus A, B, Arbidol),
including the highly pathogenic subtypes A (H1N1) pdm09 and A (H5N1), as well as other viruses - ARVI pathogens associated with severe acute respiratory syndrome (SARS, Covid 19),
rhinovirus (Rhinovirus),
adenovirus (Adenovirus),
respiratory syncytial virus (Pneumovirus) and parainfluenza virus (Paramyxovirus)).
According to the mechanism of antiviral action, Arbidol (Umifenovir) belongs to the 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.
Arbidol has interferon-inducing activity - in a study on mice, the induction of interferons was observed after 16 hours, and high titers of interferons remained in the blood up to 48 hours after administration.
Umifenovir 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 the immunoregulatory index, stimulates the phagocytic function of macrophages and increases the number of natural killer cells (NK cells).
The therapeutic effectiveness 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 frequency of development of complications associated with a viral infection and exacerbations of chronic bacterial diseases. Refers to low-toxic drugs (LD50> 4 g / kg).
Umifenovir, when taken orally in recommended doses, does not have a negative effect on the human body.
