Brief summary
1. The primary objective of this study is: * To evaluate the magnitude of the protective effect of the combination of budesonide and formoterol on an as-needed basis compared to the use of terbutaline as-needed on exercise induced bronchoconstriction in adults and adolescents with mild intermittent asthma 2. The secondary objectives of this study are: * To evaluate the magnitude of the protective effect of the combination of budesonide and formoterol as-needed compared to regular once daily use of budesonide plus terbutaline as-needed on exercise induced bronchoconstriction in adults and adolescents with mild intermittent asthma * To evaluate safety of budesonide/formoterol as-needed, terbutaline as-needed and regular use of budesonide + terbutaline as-needed as terms of adverse event

Participant flow
Recruitment details
On Visit 1, a total of 189 patients, aged 12-67, were enrolled at 10 study sites in 2 countries: Sweden and Norway. Of 189 enrolled patients, 66 patients were randomized and allocated to study treatment on Visit 3 (7 patients in Norway and 59 patients in Sweden).
Pre-assignment details
A standardized exercise test (ECT) with duration of 6 minutes, at approximately 90% of maximal aerobic capacity (as defined on Visit 1) was performed on a treadmill while breathing dry air on Visit 2. Patients with exercised induced bronchoconstriction (defined as fall in FEV1 ≥ 10% ) could be randomized on Visit 3.
