Abstract
Maintenance treatment with nebulized budesonide was studied in young children with asthma not controlled without steroids. In a blind parallel-group study for 18 weeks, 102 children, mean age 22 (5- 47) months, were randomized for treatment starting with 0.25 or 1 mg b.i.d. The patients were reviewed every 3 weeks, and if symptom control had been achieved the dose was reduced, otherwise it was kept. The clinical effect was very good with both dose regimens. The median time to 7 consecutive days without any asthma symptoms was about 1 month with both, highlighting the importance of the duration of therapy rather than the benefits of a high starting dose. In 18 of 24 children who attained the placebo stage, symptoms had reappeared at the last visit. Although an overall minimal effective maintenance dose could not be demonstrated, 47% achieved symptom control on 0.25 mg b.i.d., i.e. fulfilled criteria for further dose reduction. No significant side effects were seen. On average, 25% of the nominal dose reached the patients.
