Description

General description

Levocetirizine dihydrochloride is the R-enantiomer of cetirizine and is used for treating seasonal allergic rhinitis and chronic idiopathic urticaria. The liver metabolizes 14% of levocetirizine and rest is excreted in urine. The response of levocetirizine to histamine is comparatively higher to cetirizine.

Application

Levocetirizine dihydrochloride has been used as standard in the thin layer chromatography optimization and in preparation of racemic cetirizine standard for subcritical fluid chromatography-tandem mass spectrometry analysis.

Biochem/physiol Actions

Levocetirizine dihydrochloride is a nonsedating type histamine H1-receptor antagonist; active isomer of cetirizine

Levocetirizine hydrochloride is a nonsedating antihistamine. It is a histamine H1-receptor antagonist, the active isomer of cetirizine. Levocetirizine has high bioavailability, high affinity for and occupancy of the H1 receptor.
