| Purpose: |
|
The study will measure the improvement in lung function in subjects with asthma after
inhaling from two inhalers, Albuterol in a dry powder inhaler and albuterol in an HFA
(hydrofluoroalkane), metered dose inhaler.
|
| Study summary: |
|
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. |
