AUD2OCU: Effects of 5 mg vs. 20 mg Desloratadine on Skin Lesions in Patients With Chronic Urticaria (CU)
Study Details
Study Description
Brief Summary
The purpose of this study is to compare urticaria lesions (size, kinetics) by thermography, volumetry and digital time lapse photography in CU patients treated with desloratadine 5 mg or desloratadine 20 mg. Hypothesis: Updosing of desloratadine (20mg) is more efficient in the treatment of urticarial lesions as compared to standard dosing (5 mg desloratadine).
