["Real-life"-data on asthma control using budesonide/formoterol for both maintenance and relief: the Swiss experience].
BACKGROUND
Asthma is not adequately controlled in many patients. A new approach in asthma treatment, known as Budesonide/Formoterol Maintenance and Reliever Therapy has shown improvement in asthma control compared to conventional therapy regimens. As Switzerland was the first European country to formally approve budesonide/formoterol maintenance and reliever therapy, a patient follow-up programme was commenced in January 2006 to investigate its efficacy and safety in a "real-life" environment.


METHODS
A non randomized uncontrolled post-marketing survey involving 420 physicians in all language regions in Switzerland was carried out. 2035 patients with asthma were enrolled. Data on current asthma treatment, asthma control and unscheduled visits due to worsening asthma were recorded. Asthma control was assessed subjectively by both the patients and the physicians as well as by means of the validated 5-item Asthma Control Questionnaire (ACQ5). An ACQ score of 0.75 or less indicates well-controlled asthma.


RESULTS
Data from 2006 out of 2035 patients were analysed (mean age 44.9 +/- 19.6 years, 50.5% female). With budesonide/formoterol maintenance and reliever therapy the mean ACQ5 score improved by more than 3-fold the defined minimal important difference (MID). The percentage of patients with an ACQ score < or =0.75 increased from 4.8% at baseline to 58.0% at the end of the follow-up programme. Patient satisfaction with budesonide/formoterol for both maintenance and relief was high.


CONCLUSIONS
Budesonide/formoterol maintenance and reliever therapy improves asthma control in a non randomised real-life setting.
