结局指标
主要结局
It is the change from baseline in mean weekly Urticaria activity score-7( i.e the sum of the daily UAS i.e.(sum of wheal & itching day and night time score) self evaluation scores of 7 individual days,which could range between 0 to 42 per week) after 4 weeks of treatment
时间窗: five time points-patients will be analyased during baseline and after every 7 days for 4 weeks
次要结局
- Time to onset of action will be determined by comparing Bepotastine besilate with Levocetrizine by using participant’s daily scoring chart.(C-reactive protein and Absolute Eosinophil count will be evaluated during the baseline visit and end of therapy for predicting the outcome of treatment with Bepotastine. 2.Chronic Urticaria quality of life questionnaire)
