Antihistamine is a long-acting drug. It is the primary active metabolite of loratadine. Inhibits the cascade of allergic inflammation reactions, including the release of pro-inflammatory cytokines, including interleukins IL-4, IL-6, IL-8, IL-13, release of pro-inflammatory chemokinesRANTES), the production of superoxide anions by activated polymorphonuclear neutrophils, the adhesion and chemotaxis of eosinophils, the release of adhesion molecules such as P-selectin, IgE-mediated release of histamine, prostaglandin D2 and leukotriene C4. Thus, it prevents development and facilitates the course of allergic reactions, has antipruritic and antiexcudative action, reduces permeability of capillaries, prevents the development of edema of tissues, spasm of smooth muscles.
The drug has no effect on the central nervous system, has practically no sedative effect (does not cause drowsiness) and does not affect the rate of psychomotor reactions. Does not cause lengthening of the interval QT on the ECG.
The action of the Erius® drug starts within 30 minutes after taking inside and lasts for 24 hours.
