A Study to Assess and Compare the Effects of 5 mg vs. 20 mg Desloratadine on the Development of Cold Urticaria Lesions
An Exploratory Phase IV, Randomised, Double-Blind, Placebo Controlled Crossover Study to Compare the Effects of 5 mg vs. 20 mg Desloratadine on the Development of Experimentally Induced Urticaria Lesions
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.
