Biological Activity

[Description]:

Levocetirizine-d4 ((R)-Cetirizine-d4) is the deuterium-labeled Levocetirizine (HY-B0814)[1]. 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[2].
