Azelastine is a long-acting antiallergic substance, a derivative of phthalazinone. Azelastine is a selective H1-histamin blocker, has antihistamine, anti-allergic and membrane-stabilizing action, reduces capillary permeability and exudation, stabilizes the membrane of mast cells and prevents the release of biologically active substances (histamine, serotonin, leukotrienes, platelet activating factor, etc.), causing bronchospasm and contributing to the development of early and late stage of allergic reactions and inflammation. With local application, the systemic effect is negligible.
