-
Males or females 40 years of age or older.
-
Subjects/Patients must be able to inhale medication from the HandiHalerTM
-
Subjects/Patients must be able to perform all study-related tests including acceptable pulmonary function tests, and must be able to maintain records during the study period as required in the protocol.
-
All subjects/patients must sign an Informed Consent Form prior to participation in the trial in accordance with ICH-GCP and the local legislation, i.e., the COPD patients must give written informed consent prior to pre-study washout of their usual pulmonary medications.
-
for healthy subjects:
-
Normal spirometry as evidenced by a baseline FEV1 ≥ 80 % of predicted normal value for age, height and sex, and FEV1 ≥ 70% of FVC
-
Lifelong non-smokers or ex-smokers with a non-smoking period of at least five years and a maximum of five pack-years.
-
for COPD patients:
-
All patients must have a diagnosis of relatively stable chronic obstructive pulmonary disease and must fulfil the spirometric criteria of the respective sub-group:
-
Mild COPD: 50% ≤ FEV1 < 70% of predicted normal; FEV1/FVC < 70%.

Exclusion Criteria:
-
for healthy subjects and COPD patients:
-
Subjects or patients with clinically relevant abnormal baseline haematology, blood chemistry or urinalysis, if the abnormality defines a disease listed as an exclusion criterion will be excluded.
