The effects of controlling childhood asthma of the same daily dose (400 micrograms) of beclomethasone dipropionate, given in two or four equal divided doses from a metered aerosol, were compared in a double blind crossover study. Thirty one children aged 6-14 years completed the study. They had previously been shown to need beclomethasone by showing either symptoms or reduced peak flow when the treatment was withdrawn. They recorded their daytime and night time symptoms on a visual analogue scale and their morning and evening peak expiratory flow (PEF), and recorded their symptomatic use of bronchodilator aerosols. Spirometry was performed at the end of each treatment period. Control of asthma was good on both regimens. There were small differences in both objective and subjective measurements in favour of the four times daily regimen, but none reached statistical significance, apart from patients' assessment of daytime wheeze (p less than 0.05). In particular, the differences in the results of lung function tests were very small. Compliance was better for morning and evening doses. These results suggest that beclomethasone given as 200 micrograms twice daily is effective in controlling mild childhood asthma. It may be preferable to 100 micrograms four times daily because of better compliance and because it is unnecessary to take medication to school.
在一项双盲交叉研究中,比较了通过定量气雾剂以两种或四种等份剂量给予相同日剂量(400微克)丙酸倍氯米松对儿童哮喘的控制效果。31名6至14岁的儿童完成了该研究。他们此前在停用治疗时已表现出症状或峰值流量降低,从而证明需要使用丙酸倍氯米松。他们用视觉模拟量表记录白天和夜间症状以及早晚的呼气峰值流量(PEF),并记录使用支气管扩张气雾剂缓解症状的情况。在每个治疗期结束时进行肺功能测定。两种治疗方案对哮喘的控制效果均良好。在客观和主观测量方面,每日四次给药方案均有微小差异,但除患者对白天喘息的评估外(p<0.05),均未达到统计学意义。特别是,肺功能测试结果的差异非常小。早晚给药的依从性更好。这些结果表明,每日两次给予200微克丙酸倍氯米松对控制轻度儿童哮喘有效。由于依从性更好且无需带药上学,每日两次给药方案可能比每日四次给予100微克更可取。
