Imunofan® 2


Pharmacodynamics

The drug has immuno-regulatory, detoxifying, hepatoprotective effects and participates in the processes of inactivation of free radicals. Pharmacological action is based on three main effects: 1) immunocorrection (i.e. correction of the deficiency of the immune system), 2) normalization of the oxidative processes of the organism and 3) inhibition of the multidrug resistance mediated by the transmembrane transport pump proteins of the cell.

The direct effect of the medication develops during the first 2-3 h after injection, lasts up to 4 months, and consists of several phases: Fast, Intermediate, and Slow.

During the Fast phase (continuing up to 2-3 days) Imunofan® activates anti-oxidative ability of the organism thus preventing free radical formation and damage of the cellular membranes. At this time the detoxifying effect becomes apparent and the organism’s antioxidant defense is increased by the stimulation of a number of physiologically active compounds that prevent the cascade radical formation in the cellular membrane. The preparation inhibits the cleavage of the cell membrane phospholipids and decreases oxidized low-density lipoproteins and synthesis of arachidonic acid with the following decrease of blood cholesterol levels and production of inflammatory mediators, prostaglandins, and leukotrienes. Imunofan® can protect lymphocyte DNA from peroxide damage. The preparation prevents cytolysis and decreases transaminase activities and bilirubin levels in the blood of patients with toxic or infectious hepatitis.

During the Intermediate phase (starting 2-3 days after injection and lasting up to 7–10 days) the increase of phagocytosis and activation of the oxygen-dependent neutrophil antibacterial system occur. These effects are produced by the elevation of the hidden capacities of neutrophils to kill and eliminate intracellular bacteria and viruses, and by the increase in expression of HLA-DR molecules on the surface of T-cell, which leads to better recognition of antigen presentation by macrophages and lends a helping-effect to B-cell. These developments occur in the background of the recovery of interleukins, interferon-α or -γ production, and TNF production normalization.

During the Slow phase (starting after 7–10 days and lasting up to 4 months) the immunoregulatory effect of the drug becomes apparent. Imunofan® restores broken cellular and humoral immunity by the stimulation of the process of T-lymphocytes maturation and recovery of the Th1/Th2 lymphocytes balance. At this time an increase of specific IgM, IgG, and IgA production may be observed. The influence of the preparation on the production of specific antiviral and antibacterial antibodies is similar to the effect of some therapeutic vaccinations, except with lesser if any influence on the production of IgE and acute type hypersensitivity. As a premedicant drug in vaccination of patients with severe allergic diseases Imunofan allows reducing hyperproduction of IgE and raises early protective properties of vaccines with low content of antigen.

Imunofan effectively suppresses the multidrug resistance of tumor cells and improves their sensitivity to the action of cytostatic drugs.
