A comparison of nebulized budesonide with oral prednisolone in the treatment of exacerbations of obstructive pulmonary disease.

Nebulized corticosteroids in acute bronchospasm may offer topical anti-inflammatory activity while minimizing undesirable systemic effects. We compared the side-effect profile of nebulized budesonide (2 mg twice daily) with that of oral prednisolone (30 mg once daily) in a randomized parallel-group study of 19 adults with severe acute airway obstruction. Over the 5 days of the study, baseline forced expiratory volume in 1 second (FEV1) increased from 1.8 (95% confidence interval [CI], 0.7) to 2.1 (95% CI, 0.7) L in the group that received oral corticosteroids compared with 1.9 (95% CI, 0.7) to 2.0 (95% CI, 0.7) L in the group that received nebulized corticosteroid. All biochemical variables were similar at day 1. Comparison of budesonide treatment with prednisolone on day 5 showed that urinary corticosteroid metabolites were significantly higher (2012 [95% CI, 812] compared with 1079 [95% CI, 346] mg/24 hr [p < 0.05]), urinary androgen metabolites were not different, serum osteocalcin was elevated (2.3 [95% CI, 1.4] compared with 0.6 [95% CI, 0.6] ng/ml [p < 0.05]), and 24-hour urinary calcium to creatinine ratios were lower (0.28 [95% CI, 0.1] compared with 0.53 [95% CI, 0.2]), whereas urinary hydroxyproline to creatinine ratios were similar. The biochemical markers associated with corticosteroid side effects improve in patients treated with nebulized corticosteroids compared with patients who receive conventional treatment.
