Introduction
Design:
- 532 patients with COPD (chronic bronchitis)
- mean age 62, 79% men
- average 2.5 exacerbations/year
Patients continued using standard COPD therapy
- 70% used inhaled glucocorticoids, beta-2 adrenergic agonists or both
N-acetylcysteine 600 mg/day vs placebo
3 years duration
Results:
- after 3 years, no differences in # of exacerbations FEV1 vital capacity quality of life adverse effects related to treatment
A subgroup who did not use inhaled glucocorticoids showed significant reduction in exacerbation with N-acetylcysteine & nearly significant reduction in FEV1 decline compared with placebo.
