Levocetirizine Dihydrochloride

Research use only, not for human use.

Levocetirizine Dihydrochloride (Xyzal Dihydrochloride) is a third-generation peripheral H1-receptor antagonist. Acting as an antihistaminic agent, it specifically targets the histamine H1-receptor.

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