5. Study Description
Brief Summary
The aim of this study is to compare cold urticaria lesions by thermography, volumetry and digital time lapse photography in ACU patients treated with placebo, 5 mg and 20 mg desloratadine. Hypothesis: The updosing of desloratadine (20 mg)is more effective in the treatment of ACU symptoms as compared to standard doses (5 mg desloratadine) and placebo.
