  • CAS Number: 83881-52-1
  • Molecular Formula: C21H27Cl3N2O3
  • Molecular Weight: 461.81
  • Catalog: API Antiallergic Antihistamine

  • Cetirizine 2Hcl, a second-generation antihistamine, is a major metabolite of hydroxyzine, and a racemic selective H1 receptor inverse agonist used in the treatment of allergies, hay fever, angioedema, and urticaria. IC50 value:Target: Histamine H1 receptorCetirizine crosses the blood-brain barrier only slightly, reducing the sedative side-effect common with older antihistamines. It has also been shown to inhibit eosinophil chemotaxis and LTB4 release. At a dosage of 20 mg, Boone et al. found that it inhibited the expression of VCAM-1 in patients with atopic dermatitis. The levorotary enantiomer of cetirizine, known as levocetirizine, is the more active form. From Wikipedia.
