Product Description: Levocetirizine-d4 (dihydrochloride) is the deuterium labeled Levocetirizine. Levocetirizine ((R)-Cetirizine) is a third-generation peripheral H1-receptor antagonist. Levocetirizine is an antihistaminic agent which is the R-enantiomer of Cetirizine. Levocetirizine has a higher affinity for the histamine H1-receptor than (S)-Cetirizine and can effectively treat allergic rhinitis and chronic idiopathic urticaria[1].
