Brief Summary:
This study was designed to examine the effectiveness of a breath-operated albuterol inhaler in asthma patients who have difficulty using their standard "press-and-breathe" inhaler.

Condition or disease Intervention/treatment Phase
Asthma Drug: Albuterol HFA-BOI Drug: Albuterol HFA-MDI Phase 2

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.

Albuterol HFA breath operated inhaler, 90 mcg/sprau

Active Comparator: Albuterol HFA-MDI Drug: Albuterol HFA-MDI

Primary Outcome Measures :
  1. 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 ]

Secondary Outcome Measures :
  1. The area-under-the-effect curve of change in SGaw from basline over time [ Time Frame: Pre-dose and +120 minutes ]
  2. The maximum increase in SGaw from baseline over two hours [ Time Frame: Baseline through +120 minutes ]
  3. Time in hours to the maximum increase in SGaw from baseline [ Time Frame: Baseline through +120 minutes post-dose ]
