Title: Effects of Inhaled Tiotropium Bromide on Severity of Airflow Obstruction During Long-term Treatment in Patients With Moderately Severe Copd. Impact on Severity and Incidence of Exacerbations.
Brief Summary: The objectives of this study were to evaluate the effect of a one-year treatment with inhaled tiotropium bromide 18 mcg once daily on lung function, incidence and severity of exacerbations in patients with chronic obstructive pulmonary disease (COPD).

The secondary purpose was to explore possible relationships between lung function changes and occurrence of COPD exacerbations and to try to characterize these exacerbations.

Other protocol-defined inclusion/exclusion criteria may apply.
C: Inclusion Criteria:

1. All patients must have a diagnosis of chronic obstructive pulmonary disease (COPD) and must meet the following criteria at Visit 1:

   Patients must have relatively stable, moderate to very severe airway obstruction with a post-bronchodilator FEV1 \<=70% of predicted normal and FEV1 \<=70% of FVC post-bronchodilator (i.e. 30 minutes after inhalation of 4 puffs of 100 µg salbutamol or equivalent SABA). Predicted normal values will be calculated according to ECSC.

   For Height measured in inches Males: FEV1 predicted (L) = 4.30 x (height (inches) / 39.37)-0.029 x age (yrs) - 2.49 Females:FEV1 predicted (L) = 3.95 x (height (inches) / 39.37)-0.025 x age (yrs) - 2.60 For Height measured in metres Males: FEV1 predicted (L) = 4.30 x (height (metres)) - 0.029 x age (years) - 2.49 Females: FEV1 predicted (L) = 3.95 x (height (metres)) - 0.025 x age (years) - 2.60
2. All patients must sign an informed consent consistent with ICH-GCP guidelines prior to participation in the trial.
3. Male or female patients 40 years of age or older.
4. Patients with a history of at least one exacerbation within the past year requiring treatment with either antibiotics and/or systemic steroids and/or hospitalisation.
5. Patients must be current or ex-smokers with a smoking history of \>= 10 pack-years. (Patients who have never smoked cigarettes must be excluded.)
6. Patients must be able to perform all study-related procedures including technically acceptable pulmonary function tests (PFTs).
7. Patients must be able to inhale medication in a competent manner from the HandiHaler and a metered dose inhaler (MDI).
8. Patients must be able to maintain records (patient daily diary card) during the study period as required in the protocol.

Exclusion Criteria:

1. Significant diseases other than COPD. A significant disease is defined as a disease or condition which, in the opinion of the investigator, may put the patient at risk because of participation in the study or may influence either the results of the study or the patients' ability to participate in the study.
2. Patients with a diagnosis of asthma.
3. Patients with a life-threatening pulmonary obstruction, or a history of cystic fibrosis.
4. Patients with known active tuberculosis.
5. Patients with a known symptomatic prostatic hyperplasia or bladder neck obstruction. Patients with symptomatically-controlled prostatic hyperplasia on medication may be included and should continue their medication.
6. Patients with known narrow-angle glaucoma.

21. Patients who are currently participating in another study.
22. Patients with any respiratory infection or COPD exacerbation in the four weeks prior to the Screening Visit (Visit 1) or during the run-in period should be postponed. In the case of a respiratory infection or COPD exacerbation during the run-in period, the latter may be extended up to four weeks.
