Description
Lordestin Pharmacodynamics
Long-acting antihistamine drug. It is the primary active metabolite of loratadine. Inhibits the cascade of allergic inflammatory reactions, including the release of pro-inflammatory cytokines, including interleukins IL-4, IL-6, IL-8, IL-13, the release of pro-inflammatory chemokines (RANTES), Superoxide anion production by activated polymorphonuclear neutrophils, eosinophil adhesion and chemotaxis, release of adhesion molecules such as P-selectin, IgE-mediated release of histamine, prostaglandin D2 and leukotriene C4. Thus, it prevents and facilitates the development of allergic reactions, has antipruritic and antiexudative effects, reduces capillary permeability, prevents the development of tissue edema, 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 speed of psychomotor reactions. In clinical and pharmacological studies of desloratadine use in the recommended therapeutic dose, no prolongation of the QT interval on ECG was noted.
The action of the drug Lordestin begins within 30 minutes after oral administration and lasts for 24 hours.
