Primary Outcome Measures:
  • Percent change in SGaw (A measure of the change in specific airway conductance - how hard it is to get air into the lungs) [ Time Frame: Pre-dose and +120 minutes ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The area-under-the-effect curve of change in SGaw from basline over time [ Time Frame: Pre-dose and +120 minutes ] [ Designated as safety issue: No ]
  • The maximum increase in SGaw from baseline over two hours [ Time Frame: Baseline through +120 minutes ] [ Designated as safety issue: No ]
  • Time in hours to the maximum increase in SGaw from baseline [ Time Frame: Baseline through +120 minutes post-dose ] [ Designated as safety issue: No ]

Enrollment: 14

Study Completion Date: August 2003
Primary Completion Date: August 2003 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Albuterol HFA-BOI Drug: Albuterol HFA-BOI
Albuterol HFA breath operated inhaler, 90 mcg/sprau
Active Comparator: Albuterol HFA-MDI Drug: Albuterol HFA-MDI
Albuterol HFA multi-dose inhaler
Other Name: Proair HFA-MDI

Detailed Description:
This was a single-center, randomized, open-label, active-controlled, 2-period, 2-sequence, single dose-dose, crossover comparison of the ability of Albuterol BOI-HFA to produce bronchodilation relative to that produced by to albuterol MDI-HFA in at least 12 asthmatics with poor inhaler coordinating ability.
