| Description |
Cetirizine hydrochloride is an orally-active and selective histamine (H1)-receptor antagonist. It is a second-generation antihistamine and a human metabolite of hydroxyzine. Three important features of cetirizine are: a high specificity fort he H1-receptor; a low need for metabolism, and the existence of non-H1-dependent activities on cells involved in the pathogenesis of allergy.
Cetirizine is used to treat seasonal allergic rhinitis (SAR), perennial allergic rhinitis, useful in treating urticaria and atopic dermatitis. Cetirizine possesses also mild anti-inflammatory effects. |

| Biological Activity |
Histamine H 1 receptor antagonist that displays selectivity over other receptors at concentrations up to 10 μ M. A non-sedating antihistamine that inhibits histamine release and eosinophil chemotaxis during secondary phase allergic response. Inhibits activation of eosinophils, neutrophils and monocytes in vivo . |
