title: Is the combination inhaler of salbutamol and beclomethasone dipropionate as effective as the same agents from separate inhalers in the management of childhood asthma?
abstract: A double-blind crossover study lasting 16 weeks was carried out in children with chronic extrinsic asthma to compare the clinical effects of regular inhalations of salbutamol and beclomethasone dipropionate from a combination inhaler and regular inhalations of the same two drugs used sequentially from separate inhalers. Eighteen patients entered the study and 16 completed both 8-week treatment periods. However, there was a large amount of missing data, with only 9 complete sets of paired data; efficacy analyses were performed on data from 10 patients on separate inhaler therapy and from 14 patients on combination inhaler therapy. There were no significant differences between daily peak flow rate measurements, symptom scores, additional symptomatic bronchodilator therapy, acute exacerbations of asthma or incidence of adverse events, demonstrating that both treatments were similarly effective in controlling the patient's asthmatic symptoms. There was, however, a trend for higher peak flow values and lower symptom scores on separate inhaler therapy in this small group of asthmatic children. Although the results suggest that regular therapy using a combination inhaler is as effective as sequential administration of salbutamol and beclomethasone dipropionate from separate inhalers, it is concluded that the study should be extended to a larger group of patients to determine whether there might be any statistically significant differences between the two regimens.
