Antiviral agent Arbidol. Specifically inhibits in vitro influenza A and B viruses (Influenzavirus A, B), including the highly pathogenic subtypes A (HINl) pdm09 and A (H5N1), as well as other viruses that cause acute respiratory viral infections associated with severe acute respiratory syndrome (SARS, Umifenovir For Covid), rhinovirus (Rhinovirus), adenovirus (Adenovirus), respiratory syncytial virus (Pneumovirus) and parainfluenza virus (Paramyxovirus)).
According to the mechanism of antiviral action, it belongs to fusion (fusion) inhibitors, 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 observed after 16 hours, and high titers of interferons remained in the blood up to 48 hours after administration. Stimulates cellular and humoral immunity reactions: 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 macrophage phagocytic function 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 frequency of development of complications associated with a viral infection and exacerbations of chronic bacterial diseases.
In the treatment of influenza or SARS in adult patients, a clinical study showed that the effect of Arbidol in adult patients is most pronounced in the acute period of the disease and is manifested by a reduction in the resolution of symptoms of the disease, a decrease in the severity of the manifestations of the disease, and a reduction in the elimination of the virus.
Arbidol therapy leads to a higher incidence of symptoms on the third day of therapy compared to placebo. 60 hours after the start of therapy, the resolution of all symptoms of laboratory-confirmed influenza is more than 5 times higher than that in the placebo group. A significant effect of the drug Arbidol on the rate of elimination of the influenza virus was established, which, in particular, was manifested by a decrease in the frequency of detection of virus RNA on the 4th day.
Refers to low-toxic drugs (LD50> 4 g / kg). It does not have any negative effects on the human body when administered orally in recommended doses. Pharmacokinetics Quickly absorbed and distributed to organs and tissues. The maximum plasma concentration is reached after 1.5 hours.
Metabolized in the liver. The elimination half-life 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.
