Name Time Method Main Objective: Comparison of lung function after Salmeterol 50 µg DPI or Serevent Diskus measured as FEV1 determined as change from start to end of treatment;Secondary Objective: additional lung function variables (FVC, FEV1/FVC, FEF25%, FEF25-75%) between start and end of treatment, peak expiratory flow rate during treatment, sum score of asthma symptoms cough, wheezing, and dyspnoea, as well as the number of nocturnal awakenings during treatment, use of rescue medication during treatment;Primary end point(s): Change from start of treatment period of 2,5h-AUC of FEV1, evaluated at time points of 0, 5, 10, 15, 30, 60, 90, 120 and 150 min after treatment
