Descrizione generale

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.

Applicazioni

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.

Azioni biochim/fisiol

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.

Histamine is a well-known mediator involved in skin allergic responses through up-regulation of pro-inflammatory cytokines. Antihistamines remain the mainstay of allergy treatment, but they were found limited in efficacy and associated with several common side effects. Therefore, alternative therapeutic preferences

Cetirizine is a zwitterionic second-generation antihistamine containing R- and S-enantiomers, levocetirizine, and (S)-cetirizine. Levocetirizine is known to have a higher affinity for the histamine H₁ receptors than (S)-cetirizine; ligand-receptor docking simulations have suggested the importance of the formation of a
