OBJECTIVE: To determine the ability of budesonide via an inhaler (Pulmicort Turbuhaler; Astra Draco AB) to replace oral glucocorticosteroids (GCSs) in adult subjects with moderate-to-severe asthma. DESIGN: Double-blind, randomized, and placebo-controlled study, with parallel groups. SETTING: Multicenter study in outpatient setting. PARTICIPANTS: Eighty men and 79 women, aged 20 to 69 years, with moderate-to-severe asthma and a mean FEV1 of 58.3% predicted normal. All subjects were receiving oral GCS treatment and 79% of subjects were also receiving inhaled beclomethasone dipropionate (BDP). The mean daily doses of prednisone at baseline, including converted dose of BDP, for the placebo, budesonide 400 microg, and budesonide 800 microg, respectively, were 19.7 mg, 19.5 mg, and 18.7 mg. MEASUREMENTS AND INTERVENTIONS: After a 2-week baseline period, subjects entered a 20-week treatment period, during which the oral dose of prednisone was reduced by forced down-titration at 2-weekly intervals. RESULTS: Subjects receiving 400 microg or 800 microg bid of budesonide achieved a significantly greater reduction (82.9% and 79.0% respectively) in oral GCS dose compared with placebo-treated subjects (27%; p<0.001). Two thirds of the subjects receiving budesonide were able to achieve sustained oral corticosteroid cessation, compared with 8% in the placebo group. Additionally, both doses of budesonide resulted in significant improvement in results of pulmonary function tests and asthma symptoms scores, and a significant decrease in the use of bronchodilator therapy. The mean plasma cortisol levels before and after adrenocorticotropic hormone stimulation increased most toward the normal range in the budesonide-treated groups compared with placebo-treated subjects. CONCLUSION: Budesonide administered via Turbuhaler has a significant oral GCS-sparing capacity with maintained or improved asthma control in adult subjects with moderate-to-severe asthma. |
