Eligibility criteria:

        Inclusion criteria:

             legislation prior to participation in the trial (i.e. prior to any trial procedures,
             including any pre-trial washout of medications and medication restrictions for
             pulmonary function test at Visit 1).

          2. Male or female patients aged at least 18 years but not more than 75 years.

          3. All patients must have at least a 3 month history of asthma at the time of enrolment

             criterion 5.

          4. The initial diagnosis of asthma must have been made before the patient's age of 40.

          5. The diagnosis of asthma has to be confirmed at Visit 1 with a bronchodilator
             reversibility (15 minutes after 400 mcg salbutamol (albuterol)) resulting in a Forced
             Expiratory Volume in one second (FEV1) increase of at least 12% and at least 200mL.

          6. All patients must have been on maintenance treatment with a medium, stable dose of
             inhaled corticosteroids for at least for 4 weeks prior to Visit 1.

          7. All patients must be symptomatic at Visit 1 (screening) and prior to randomisation at
             Visit 2 as defined by an Asthma Control Questionnaire (ACQ) mean score of at least
             1.5.

          8. All patients must have a pre-bronchodilator FEV1 at least 60% and less than or equal
             to 90% of predicted normal at Visit 1.

          9. Variation of absolute FEV1 values of Visit 1 (pre-bronchodilator) as compared to Visit
             2 (pre-dose) must be within ± 30%.

         10. Patients must be never-smokers or ex-smokers who stopped smoking at least one year
             prior to enrolment (Visit 0) and who have a smoking history of less than 10 pack
             years.

         11. Patients must be able to use the Respimat® inhaler and metered dose inhaler correctly.

         12. Patients must be able to perform all trial related procedures including technically
             acceptable pulmonary function tests and use of electronic diary/peak flow meter.

        Exclusion criteria:

          1. Patients with a significant disease other than asthma. A significant disease is
             defined as a disease which, in the opinion of the investigator, may (i) put the
             patient at risk because of participation in the trial, or (ii) influence the results
             of the trial, or (iii) cause concern regarding the patient's ability to participate in
             the trial.

          2. Patients with a clinically relevant abnormal screening (Visit 1) haematology or blood
             chemistry if the abnormality defines a significant disease as defined in exclusion
             criterion 1.

          3. Patients with a recent history (i.e. six months or less) of myocardial infarction.

          4. Patients who have been hospitalised for cardiac failure during the past year.

          5. Patients with any unstable or life-threatening cardiac arrhythmia or cardiac
             arrhythmia requiring intervention or a change in drug therapy within the past year.
