Bronchoreversibility and Radiologic Morphology of Emphysema


To assess response to bronchodilation with tiotropium plus salbutamol in patients with severe emphysema and analyze relationships between bronchoreversibility response and semiquantitative computed-tomography based emphysema severity measures.

Full Title of Study: “Response to Bronchodilation With Tiotropium Plus Salbutamol Correlates With Radiologic Morphology of the Lung in COPD of the Emphysematous Phenotype”

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: December 2013


  • Drug: Bronchodilators
    • Administration of both albuterol and tiotropium bromide after a 48h period of washout from all bronchodilators, followed by spirometry and plethysmography

Arms, Groups and Cohorts

  • Bronchodilators
    • Patients with severe heterogeneous emphysema selected as potential candidtes for lung volume reduction surgery. Bronchodilators employed for the study include albuterol 200µg and tiotropium bromide 18 µg administered by puffs following a first spirometry and plethysmography performed after a washout period of 48h from all bronchodilators and subsequently repeated within 30 min after bronchodilators administration.

Clinical Trial Outcome Measures
