Mean of daily use of salbutamol (albuterol) rescue medication as needed during the entire study period. Assessed by patients at home using the AM2+ device (overall means obtained during each period of randomised treatment excluding the data of the first 2 weeks will be compared). Means are adjusted for treatment, period, patient and study baseline.
2-4 weeks
Percentage of Asthma Symptom Free Days
大体时间：2-4 weeks
Percentage of asthma-symptom free days after the first 2 weeks of each treatment period was calculated as the number of symptom-free days divided by the number of days on treatment multiplied by 100. A symptom-free day was defined as a day in which no asthma symptoms were recorded, no rescue medication was recorded, activities during the day were not at all limited due to asthma, no shortness of breath during the day was recorded, no wheezing or coughing during the day and no night-time awakenings due to asthma were recorded. Assessed by patients at home using the AM2+ device.
2-4 weeks
Number of Patients Categorized by Highest Number of Night Time Awakenings (Overall)
大体时间：2-4 weeks
Assessed by patients at home using the AM2+ device after the first 2 weeks of each period of randomised treatment.
2-4 weeks
Number of Patients Categorized by Worst Asthma Daytime Symptoms (Overall)
大体时间：2-4 weeks
Assessed by patients at home using the AM2+ device after the first 2 weeks of each period of randomised treatment.
2-4 weeks
Number of Patients Categorized by Worst Asthma Nighttime Symptoms (Overall)
大体时间：2-4 weeks
Assessed by patients at home using the AM2+ device after the first 2 weeks of each period of randomised treatment.
2-4 weeks
Total Asthma Quality of Life Questionnaire (AQLQ(s)) Score
大体时间：4 weeks
Total score from the Standardised Asthma Quality of Life Questionnaire (AQLQ (s)) at the end of each 4 week treatment period. The AQLQ(s) contains 32 questions, each question has a 7 point scale from 1 (highest intensity) till 7 (no symptoms). Total score was defined as the sum of all items divided by the number of items.
4 weeks
Total Asthma Control Questionnaire (ACQ) Score
大体时间：4 weeks
Control of asthma as assessed by the ACQ at the end of each 4-week treatment period.The ACQ contains 7 questions, each question has a 7 point scale from 0 (no symptoms) till 6 (highest intensity). Total score was defined as the sum of all items divided by the number of items.
4 weeks
Potassium 1 Hour Pre-dose
大体时间：4 weeks
Effect on potassium evaluated 1 hour pre-dose. Analysis is based on the log of the potassium values. For the geometric means, the results were back-transformed to the original scale.
4 weeks
Potassium 1 Hour Post-dose
大体时间：4 weeks
Effect on potassium evaluated 1 hour post-dose. Analysis is based on the log of the potassium values. For the geometric means, the results were back-transformed to the original scale.
4 weeks
Potassium 3 Hours Post-dose
大体时间：4 weeks
Effect on potassium evaluated 3 hours post-dose. Analysis is based on the log of the potassium values. For the geometric means, the results were back-transformed to the original scale.
4 weeks
Clinical Relevant Abnormalities for Vital Signs, Blood Chemistry, Haematology, Urinalysis and ECG
大体时间：4 weeks
Clinical relevant abnormalities for Vital Signs, Blood Chemistry, Haematology, Urinalysis and ECG. New abnormal findings or worsening of baseline conditions were reported as Adverse Events.
