Pharmacodynamics.

Antiviral agent. Specifically suppresses in vitro influenza viruses A and B (Influenzavirus A, B), including highly pathogenic subtypes A(H1N1)pdm09 and A(H5N1), and other viruses – causative agents of acute respiratory viral infections (ARI), associated with severe acute respiratory syndrome (SARS), rhinovirus (Rhinovirus), adenovirus (Adenovirus), respiratory syncytial virus (Pneumovirus), and parainfluenza virus (Paramyxovirus).

In terms of the mechanism of antiviral action it refers to fusion inhibitors (fusion), interacts with hemagglutinin of the virus and prevents fusion of the lipid shell of the virus and cell membranes.

It has a moderate immunomodulatory effect, increases the body’s resistance to viral infections. It possesses interferon-inducing activity – in researches on mice interferon induction was noticed after 16 hours, and high titers of interferon were maintained in blood up to 48 hours after administration.

Stimulates cellular and humoral immune reactions: it increases number of lymphocytes in blood, in particular of T-cells (CD3), increases number of T-helpers (CD4) without affecting the level of T-suppressors ‑(CD8), normalizes the immunoregulatory index, stimulates phagocytic function of macrophages and increases the number of natural killer (NK-cells).

Therapeutic effectiveness in viral infections is manifested in reduction of duration and severity of the course of the disease and its main symptoms as well as in the decrease of the rate of development of complications due to viral infection and exacerbations of chronic bacterial diseases.

In treatment of influenza or acute respiratory viral infections in adults the clinical trial showed that the effect of Arbidol^® in adults is most pronounced in acute period of disease and shows shorter time of resolution of disease symptoms, less severe manifestations of disease and shorter time of virus elimination.

Therapy with Arbidol^® results in higher rate of resolution of symptoms on the third day of therapy compared to placebo. In 60 hours after the beginning of therapy the resolution of all symptoms of laboratory confirmed flu is more than 5 times higher than in the placebo group.

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

Related to low-toxicity drugs (LD₅₀ > 4 g/kg). It does not have any negative effect on human body when administered orally in recommended doses.

Pharmacokinetics.

It is rapidly absorbed and distributed to organs and tissues. Maximal concentration in blood plasma is reached after 1.5 hours. It is metabolized in the liver. Period of half-life is 17-21 hours. About 40% is excreted unchanged, mainly in bile (38.9%) and in small amount in kidney (0.12%). During the first day 90% of the administered dose is eliminated.

Indications

Prevention of flu and colds, Colds, ARI, Flu

• Prevention and treatment in adults and children: Flu A and B, other ARI.

• The complex therapy of recurrent herpetic infection.

• Prevention of postoperative infectious complications.

• Comprehensive therapy of acute intestinal infections of rotavirus etiology in children over 6 years.
