Effect of inhaled beclomethasone dipropionate in the treatment of recurrent wheezing in infancy and early childhood

Abstract

Forty-one children, aged six to 36 months (mean, 23.3 months), with a past history of acute bronchiolitis with or without recurrent wheezing episodes were treated with either a beclomethasone dipropionate metered dose inhaler 150 microgram twice daily, or a placebo for 12 weeks. Aerosols were inhaled through an AeroChamber (Trudell, Canada) using a mask. The patients were followed up biweekly. The two groups were well matched in anthropometric data and frequency of wheezing prior to the study being undertaken. At the end of four to six weeks, the beclomethasone dipropionate treatment group showed a significant improvement in both wheezing and sleep patterns, and systemic steroid therapy was able to be tapered. No significant side effect could be ascribed to this treatment.
