Spirometry was performed according to internationally accepted standards. Time to the peak (maximum) FEV1 is recorded. Analysis of Covariance with treatment, period, sequence and subject nested within sequence as fixed effects and period FEV1 baseline as a covariate.

Spirometry was conducted according to internationally accepted standards post-dose at 0, 15 and 30 minutes; 1, 2, 3, 4, 8, 12 hours on Day 1 and 23.16 and 23.75 hours on Day 2. FEV1 is the amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation.

Spirometry was conducted according to internationally accepted standards post-dose at 0, 15 and 30 minutes; 1, 2, 3, 4, 8 and 12 hours on Day 1 and 23.16 and 23.75 hours on Day 2. FEV1/FVC ratio is the percentage of the total FVC that is expelled from the lungs during the first second of forced exhalation.

FEV1/FVC ratio is the percentage of the total FVC that is expelled from the lungs during the first second of forced exhalation.

Spirometry was conducted according to internationally accepted standards post-dose at 0, 15 and 30 minutes; 1, 2, 3, 4, 8 and 12 hours on Day 1 and 23.16 and 23.75 hours on Day 2. The forced expiratory flow (FEF) 25%-75% measurement describes the amount of air expelled from the lungs during the middle half (25% - 75%) of the forced vital capacity test and is measured using spirometry.

Spirometry was conducted according to internationally accepted standards post-dose at 0, 15 and 30 minutes; 1, 2, 3, 4, 8 and 12 hours on Day 7 and 23.16 and 23.75 hours on Day 8. The forced expiratory flow (FEF) 25%-75% measurement describes the amount of air expelled from the lungs during the middle half (25% - 75%) of the forced vital capacity test and is measured using spirometry.

Spirometry was conducted according to internationally accepted standards at predose, 5, 15 and 30 minutes, 1, 2 and 4 hours post-dose on Day 1 and Day 7. The standardized (with respect to the length of time) area under the curve (AUC) for FEV1 was calculated using trapezoidal rule between 5 min and 4 h post. Analysis of Covariance with treatment, period, sequence and subject nested within sequence as fixed effects and period FEV1 baseline as a covariate.

Spirometry was conducted according to internationally accepted standards at predose, 5 , 15 and 30 min, 1, 2, 4, 8 and 12 hours post-dose on Day 1 and Day 7. The standardized (with respect to the length of time) area under the curve (AUC) for FEV1 was calculated using trapezoidal rule between 5 min and 12 h post. Analysis of covariance with treatment, period, sequence and subject nested within sequence as fixed effects and FEV1 period baseline as a covariate.

PEFR was measured on all days from Screening Visit 2 to end of study visit: twice daily pre-dose (prior to Inhaled Corticosteroids) and approximately 12 hours post-dose (during the treatment period). Each subject was provided with a PEFR meter and recorded the PEFR readings in a daily diary. repeated measures. Analysis of covariance with treatment, period, sequence, day and treatment-day interaction as fixed effect and subject as a random effect and baseline PEFR as a covariate in the model.

Salbutamol (100 µg/puff) was used as rescued medicine. The total number of puffs per day was calculated and divided by the number of days with data to determine the mean daily number of puffs of rescue medication for each patient and was recorded in the patient diary from Baseline until Day 8 of Treatment Period 4. Analysis of covariance with treatment, period, sequence, and subject nested within sequence as fixed effect.

Adverse event are defined as any unfavorable and unintended diagnosis, symptoms, sign (including an abnormal lab finding), syndrome or disease which either occurs during the study, having been absent at baseline, or if present at baseline appear to worsen. Serious adverse events are any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization , cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgments of the investigators represent significant hazards.
