Criteria

Inclusion Criteria:

1. Male or female patients 40 years of age or older

2. A diagnosis of COPD as defined by American Thoracic Society (ATS) criteria. Patients must have relatively stable, moderate to severe airway obstruction with a baseline FEV 1 <=65% of predicted normal and FEV1/FVC >=70%.

3. A smoking history of more than ten pack-years. A pack-year is defined as the equivalent of smoking one pack of 20 cigarettes per day for a year

4. Able to perform technical satisfactory pulmonary function test

5. Able to be trained in the proper use of a MDI

6. Having signed an informed consent from prior to participation in the trial

7. Affiliation to the French social security system or beneficiary of such a system

Exclusion Criteria:

1. Significant disease other than COPD. A significant disease is defined as a disease which in the opinion of the investigator may either put the patient at risk because of participation in the study or a disease which may influence the results of the study or the patient's ability to participate in the study

2. Clinical relevant abnormal baseline hematology, blood chemistry or urinalysis. If the abnormality defines a disease listed as an exclusion criterion, the patient is excluded

3. Serum glutamic oxaloacetic transaminase (SGOT) >80 IU/L; serum glutamic pyruvic transaminase (SGPT) >80IU/L, bilirubin >2.0mg/dL or creatinine >2.0mg/dL

4. Serum potassium level above or below the normal range

5. Total blood eosinophil count >=600/mm³

6. Recent history (i.e., one year or less) of myocardial infarction

7. Recent history (i.e., three years or less) of heart failure or any cardiac arrhythmia requiring drug therapy

8. History of cancer, other than treated basal cell carcinoma, within the last five years

9. History of life-threatening pulmonary obstruction, or a history of cystic fibrosis or bronchiectasis

10. History of thoracotomy with pulmonary resection. History or a thoracotomy for other reasons should be evaluated as per exclusion criteria no. 1

11. History of asthma, allergic rhinitis or atopy

12. History of or active alcohol or drug abuse

13. Known active tuberculosis

14. Upper respiratory tract infection or COPD exacerbation in the six weeks prior to screening visit or between the screening visit and visit 2

15. Known symptomatic prostatic hypertrophy or bladder neck obstruction

16. Known narrow-angle glaucoma

17. Current significant psychiatric disorders

18. Regular use of daytime oxygen therapy

19. Use of beta-blocker medications, mono-amine oxidase inhibitors or tricyclic antidepressants

20. Use of cromolyn sodium or nedocromil sodium

21. Use of antihistamines.

22. Use of oral corticosteroid medication at unstable doses (i.e., less than six weeks on a stable dose before screening visit or a change between the screening visit and visit2) or at a dose in excess of the equivalent of 10 mg of prednisone per day or 20mg every other day

23. Use of oral beta-adrenergics or long-acting beta-adrenergics such as salmeterol (Serevent®) and formoterol in the two weeks prior to the screening visit or between the screening visit and visit 2

24. Changes in the therapeutic plan within the last six weeks prior to the screening visit or between the screening visit and visit 2, excluding changes from long acting or oral beta-adrenergics to short acting inhaled beta-adrenergics for purposes of this trial

25. Pregnant or nursing women or women of childbearing potential not using a medically approved means of contraception

26. Known hypersensitivity to anti-cholinergic or beta-agonist drugs or any other component of either Combivent® formulations

27. Use of an investigational drug within one month or six half lives prior to the screening visit

28. Previous participation in this study

29. Patient deprived of their freedom by a judicial or administrative decision

30. Patient leaving in medical or social establishments

31. Patient hospitalized for mental disorder without his (her) consent

32. Patient under guardianship

33. Patient in emergency situations
