Pharmacological action
Blocker of histamine H1 receptors with antiserotonin activity. Moderately blocks serotonin 5HT1 receptors, weakening the effects of histamine and serotonin allergy mediators. Histamine causes the clinical manifestations of allergic inflammation: edema (capillary permeability increases), flushing of the skin (vasodilation), skin itching and pain.
The peculiarity of sechifenadine is that it has an antihistamine effect not only blocking histamine H1 receptors, but also reducing the histamine content in tissues by accelerating its destruction by diamine oxidase.
In allergic diseases, the level of serotonin in the blood also rises. Serotonin increases blood pressure, causes bronchospasm, increases capillary permeability, enhances the action of inflammatory mediators – histamine, bradykinin, prostaglandins. Sechifenadine prevents or weakens the spasmogenic effect of histamine and serotonin on the smooth muscles of the bronchi, intestines, and vessels, impaired capillary permeability and the development of edema.
Sechifenadine has a pronounced antipruritic and antiexudative effect of a prolonged nature.
Affects the immunological reactivity of the body, reducing the number of B-lymphocytes in the spleen, bone marrow, lymph nodes, and also reduces the increased concentration of immunoglobulins of classes A and G.
