         12. The patient is able to correctly use the MDPI device, either alone or with assistance
             by a parent/guardian.

        Exclusion Criteria

          1. Known hypersensitivity to albuterol or any of the excipients in the inhaler
             formulations (eg, lactose, ethanol)

          2. Participation (receiving study medication) in any investigational drug trial within
             the 30 days preceding the SV or planned participation in another investigational drug
             trial at any time during this trial

          3. History of severe milk protein allergy

          4. History of a respiratory infection or disorder (including, but not limited to

          5. Any asthma exacerbation requiring oral corticosteroids within 3 months of the SV. A
             patient must not have had any hospitalization for asthma within 6 months prior to the
             SV.

          6. Initiation of immunotherapy during the study period or dose escalation during the
             study period. Patients being treated with immunotherapy prior to the SV must be using
             a stable (maintenance) dose (90 days or more) to be considered for inclusion.

          7. History of life-threatening asthma that is defined for this protocol as an asthma
             episode that required intubation and/or was associated with hypercapnea, respiratory
