简要总结

The purpose of this study was to evaluate whether 2 puffs of fixed combination of aerosolized 120 mcg salbutamol sulphate (equivalent to 100 mcg of the base) + 20 mcg ipratropium bromide confers significant additional protection against metacholine induced bronchoconstriction in asthmatic atopic patients when compared to 2 puffs of aerosolized 100 mcg salbutamol alone.

入选标准

  • Male or female patients with a diagnosis of asthma according to the American Thoracic Society Criteria
  • Patients aged 7 to 12 years inclusive
  • Patients able to perform spirometry
  • Patients with FEV1 (forced expiratory volume in the first second) ≥ 80% of predicted normal value after saline
  • Patients with PD20 (provocative dose that reduces FEV1 by 20 %) metacholine lower than 8 mg/ml
