Pharmachologic effect

An allergic reaction occurs when a foreign protein (allergen) enters the human body, to which an individual has a heightened sensitivity - there are already special immune memory cells in it that can synthesize antibodies.

It is during the contact of the antigen and the antibody capable of neutralizing it, and an allergic reaction develops, which is accompanied by the release of biologically active substances - histamine, serotonin, bradykinin. It is their effect on the body that explains the variety of reactions - the appearance of a dramatic expansion of blood vessels, edema of mucous membranes and subcutaneous fat, cough, runny nose of various rashes on the skin, a sharp and uncontrolled decrease in blood pressure.

The introduction into the human body of the active ingredient of the drug Tavegil, clemensin, changes the mechanism of histamine interaction with specific cell receptors - they become insensitive to this substance. Accordingly, the intensity of immune hypersensitivity reactions decreases in the body, the symptoms of allergy are eliminated, the itching and unpleasant sensations disappear in the patient.
