Chronic Idiopathic Urticaria | The Efficacy and Safety of Desloratadine With Levocetirizine in Treatment of Chronic Idiopathic Urticaria

Chronic Idiopathic Urticaria research study

What is the primary objective of this study?

Objective: To compare the efficacy of desloratadine 5mg (Denosin®) and levocetirizine 5mg (Xyzal®) once daily in the treatment of patients with CIU over 6 weeks. Trial design: Randomized, Double-Blind, Active-Controlled, Parallel-Group Study. Primary end point: To evaluate the change in average AM/PM reflective pruritus score from baseline recorded in the subjects’ diaries during the first two weeks of the treatment. Secondary Objectives: To assess the efficacy and safety of desloratadine 5mg (Denosin®) and levocetirizine 5mg (Xyzal®) once daily in the treatment of subjects with CIU over 6 weeks.
