Comparison of the Effects of Indacaterol and Tiotropium on Inspiratory Capacity
Chronic Obstructive Pulmonary Disease
About this trial
This is an interventional treatment trial for Chronic Obstructive Pulmonary Disease focused on measuring COPD, indacaterol, tiotropium

- Smoking history of at least 10 pack-years.
- Forced expiratory volume in 1 second (FEV1) < 80% and ≥ 50% of the predicted normal value.
- Post-bronchodilator FEV1/Force vital capacity (FVC) < 0.7.
Exclusion Criteria:
- Patients who have had a COPD exacerbation requiring systemic glucocorticosteroid treatment or antibiotics and/or hospitalization in the 6 weeks prior to screening.
- Patients who have had a respiratory tract infection within 6 weeks prior to screening.
- Patients with concomitant pulmonary disease.
- Patients with alpha-1-antitrypsin deficiency.
- Patients with contraindications for tiotropium treatment.

Indacaterol 150 μg-tiotropium 18 μg-placebo
Tiotropium 18 μg-placebo-indacaterol 150 μg
Placebo-indacaterol 150 μg-tiotropium 18 μg
Patients received indacaterol 150 μg once. After a 5-9 days washout period, patients received tiotropium 18 μg once. After a second 5-9 days washout period, patients received placebo (matching indacaterol) once. All treatments were delivered via a single dose dry powder inhaler (SDDPI). The short-acting β2-agonist salbutamol was available for rescue use throughout the study.
