ATX code: J05AX13

Pharmacological properties

Pharmacodynamics .

Antiviral agent. Specifically inhibits in vitro influenza A and B viruses (Influenzavirus A, B), including highly pathogenic subtypes A(H1N1)pdm09 and A(H5N1), as well as other viruses that cause acute respiratory viral infections (SARS associated with severe acute respiratory syndrome (SARS), rhinovirus, adenovirus, respiratory syncytial virus (Pneumovirus) and parainfluenza virus (Paramyxovirus)).

According to the mechanism of antiviral action, it belongs to fusion inhibitors (fusions), interacts with viral hemagglutinin and prevents the fusion of the lipid envelope 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 mouse study, interferon induction was observed as early as 16 hours, and high interferon titers persisted in the blood up to 48 hours after use.

It stimulates cellular and humoral immune responses: increases the number of lymphocytes in the blood, especially T-cells (CD3), increases the number of T-helper cells (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 killers (NK cells).

Therapeutic efficacy 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 frequency of complications associated with viral infection and exacerbations of chronic bacterial diseases.

In the treatment of influenza or ARVI 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 time of resolution of symptoms of the disease, a decrease in the severity of disease manifestations and a reduction in the time of virus elimination.

Arbidol®therapy It leads to a higher rate of relief 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 in the placebo group.

A significant effect of Arbidol®has been established the rate of elimination of the influenza virus, which, in particular, was manifested by a decrease in the frequency of detection of RNA of the virus on the 4th day.

It belongs to low-toxic drugs (LD₅₀>4 g / kg). It does not have any negative effects on the human body when administered orally at the recommended doses.

Pharmacokinetics.

It is quickly absorbed and distributed to organs and tissues. The maximum concentration in blood plasma when taken at a dose of 50 mg is reached in 1.2 hours, at a dose of 100 mg – in 1.5 hours. It is metabolized in the liver. The elimination half-life is 17-21 hours. About 40% is excreted unchanged, mainly in the bile (38.9%) and in a small amount by the kidneys (0.12%). During the first day,90% of the administered dose is removed.

Indications

• Prevention and treatment in adults and children: influenza A and B, other acute respiratory infections.

• Complex therapy of acute intestinal infections of rotavirus etiology in children older than 3 years.

• Complex therapy of chronic bronchitis, pneumonia and recurrent herpetic infection.

• Prevention of postoperative infectious complications.
