Double-Blind Study with Duovent and Placebo in 20 Asthmatic Children

Abstract

Duovent activity was compared with placebo in a double-blind study carried out in 20 children, aged between 5 and 14 years, suffering from bronchial asthma. The experiment lasted 2 weeks. The patients were divided into two groups. In the 1st week, group I was treated with Duovent and group II with placebo, in the 2nd week vice versa. There was no reduction in cough or dyspnea in subjects treated with placebo, and only a slight increase (not significant) in peak expiratory flow (PEF). In the subjects treated with Duovent, there was a clear reduction in cough and dyspnea and a significant increase in PEF. The effect of the drug was still evident after 8 h, and it was well tolerated without side effects. The high number of additional sprays required during the placebo period was further evidence of the therapeutic efficacy of Duovent, which in almost all cases met the daily therapeutic requirements of the small patients. Duovent appears to be an effective drug in the treatment of bronchial asthma in children, both clinically and functionally.
