Detailed Description

The study objective is to compare the efficacy and safety of albuterol in a dry powder inhaler (DPI) and albuterol in an HFA metered dose inhaler (MDI) after a cumulative dose of 1440mcg administered as 1+1+2+4+8 inhalations (90mcg per inhalation). Another study objective is to compare the pharmacokinetics (metabolism) of albuterol with the two inhalers. The pharmacokinetics of albuterol will be examined in half (24) of the study subjects. To participate in the study, patients must provide written informed consent, washout any prohibited medications and pass all the screen criteria. Once this is done, there will be two treatment visits. At each visit the subject will inhale with both types of inhalers. At each visit, one inhaler will have active drug (albuterol) and one inhaler will have placebo (dummy). The inhaler with the active drug will be switched at the two visits in a random manner. At each visit the subject will inhale with each inhaler a total of 16 times by a specific schedule. The subject will inhale from each inhaler once (1), wait 30 minutes, inhale from each inhaler once (1), wait 30 minutes, inhale from each inhaler twice (2), wait 30 minutes, inhale from each inhaler four times (4), wait 30 minutes, and then inhale from each inhaler eight times (8). The total time to complete the inhalations should be about 2 hours. Following that, there will be a series of assessments taken at regular times with vital signs measured up to 6 hours, ECG (electrocardiogram) assessed up to 4 hours, blood taken to measure potassium and glucose up to 4 hours, lung function evaluated with spirometry up to 6 hours, and for those subjects participating in the pharmacokinetic evaluation blood will be drawn up to 12 hours. The two study treatment visits will be 3 to 14 days apart. Following these visits, there will be a study concluding visit 1 to 5 days later.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Albuterol dry powder inhaler
The participants will receive albuterol delivered with the a DPI (dry powder inhaler) and placebo with an HFA MDI inhaler (hydrofluoroalkane metered dose inhaler).
Drug: Albuterol dry powder inhaler
Albuterol DPI (dry powder inhaler) delivers 90mcg of albuterol in the excipient lactose with each inhalation. Albuterol will be given on two treatment days (3 to 14 days apart). On each treatment day albuterol will be given as a cumulative dose of 1440mcg as a series of inhalations using both Albuterol in a DPI (dry Powder inhaler) and albuterol in an HFA MDI (hydrofluoroalkane metered dose inhaler), ProAir. One inhaler will contain active drug and one inhaler will contain placebo.
Active Comparator: Albuterol HFA MDI
The participants will receive albuterol delivered with an HFA MDI inhaler (hydrofluoroalkane metered dose inhaler) and placebo with albuterol in a DPI (dry powder inhaler).
Drug: Albuterol HFA MDI (hydrofluoroalkane metered dose inhaler)
Albuterol HFA MDI (hydrofluoroalkane metered dose inhaler) delivers 90mcg of albuterol with each inhalation. Albuterol will be given on two treatment days (3to 14 days apart). On each treatment day albuterol will be given as a cumulative dose of 1440mcg as a series of inhalations using both Albuterol DPI (dry powder inhaler) and the comparator inhaler, albuterol HFA MDI (hydrofluoroalkane metered dose inhaler).One inhaler will contain active drug and one inhaler will contain placebo.

Secondary Outcome Measures

Outcome Measure
Time Frame
Baseline-adjusted FEV1 (forced expiratory volume in 1 second) AUC0-6 (area under the serum concentration time curve from time 0 to 6 hours) following the administration of the final cumulative dose
Time Frame: At the two study treatment visits, FEV1 (forced expiratory volume in 1 second) will be measured prior to drug administration and 7 time points ( 30 minutes and 1,2,3,4,5 and 6 hours) after the 5th and final dose.
At the two study treatment visits, FEV1 (forced expiratory volume in 1 second) will be measured prior to drug administration and 7 time points ( 30 minutes and 1,2,3,4,5 and 6 hours) after the 5th and final dose.
ECGs (electrocardiogram) will assess the maximum and mean change from baseline of the corrected QT interval (QT interval measures the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle) following study drug.
Time Frame: Serial ECGs (electrocardiogram) will be taken at baseline (5 minutes pre-dose), 15 minutes after each dose, and also at 30 minutes, 60 minutes, 2, 3, and 4 hours following the last cumulative dose in order to calculate the corrected QT interval.
Serial ECGs (electrocardiogram) will be taken at baseline (5 minutes pre-dose), 15 minutes after each dose, and also at 30 minutes, 60 minutes, 2, 3, and 4 hours following the last cumulative dose in order to calculate the corrected QT interval.
Changes in blood pressure will be evaluated by the maximum change (systolic) and minimum change (diastolic) from baseline blood pressure, and the weighted mean change from baseline in systolic and diastolic blood pressure.
Time Frame: Serial measurements of systolic and diastolic blood pressure will be taken at baseline (15 minutes pre-dose), 15 minutes after each dose, and also at 30 minutes, 60 minutes, 2, 3, 4, 5, and 6 hours following the last cumulative dose.
Serial measurements of systolic and diastolic blood pressure will be taken at baseline (15 minutes pre-dose), 15 minutes after each dose, and also at 30 minutes, 60 minutes, 2, 3, 4, 5, and 6 hours following the last cumulative dose.
