DefinitionThis section has been translated automatically.
Left-turning active R-enantiomer of cetirizine. Selective 2nd generation H1 antihistamine.
Pharmacodynamics (Effect)This section has been translated automatically.
Competitive H1 receptor antagonist. Levocetirizine binds to the H1-receptor, displaces the body's own histamine ligands and therefore causes a reduction in the intensity of allergic reactions. Due to its dissolution behavior, levocetirizine, in contrast to the H1 antihistamines of the 1st generation, no longer reaches the central nervous system or only in extremely small quantities.
