Formoterol Via DPI Then Formoterol Via Nebulizer
Group A: Received Formoterol 12 µg via DPI and placebo via nebulizer at treatment visit #1, and then Formoterol 20 µg (solution form) via nebulizer and placebo via DPI at treatment visit 2. Placebo: Comparison of drug administered via a nebulizer versus a dry powder inhaler. The placebo used will be sterile, preservative free, normal saline for inhalation for the nebulizer and a matched capsule without active drug for the dry powder inhaler. All patients will receive 2 ml of normal saline with the nebulizer to match the volume of nebulized formoterol solution. Patients will receive formoterol and placebo at both study visit #1 and visit #2.

PRIMARY outcome

Timeframe: Baseline through study completion (visit 1 through visit 2)

Population: Participants who received a dose of formoterol via nebulizer AND formoterol via dry powder were included. One patient did not complete the full study, which is why only 6 participants who took formoterol with Nebulizer were analyzed. Collected at baseline, visit 1, and visit 2 at pre-dose then 30 minutes,1hr, 2hr, and 4hr post-dose

The difference between the values of area under the response curve for FEV1 from baseline through four hours (AUC FEV1 0-4h) after inhalation of formoterol with a nebulizer or a dry powder inhaler.

A percentage of change from baseline FEV1 to each serial measurement of FEV1 was collected. The % of change at each time point was then used to get a measure of overall percentage change of the predicted FEV1 value.

The Shortness of Breath Modified Borg Dyspnea Scale The scale goes from 0-10, zero meaning no difficulty breathing and ten meaning maximal difficulty. A decrease of score indicates an improvement. Patients were asked to complete the scale pre-dose and again one hour post formoterol dose. This was completed at both visit 1 and visit 2. The value recorded was the difference between the baseline value and the post 60 minute value.
