Summary of participants with adverse events

Detailed description: This is a single center, open-label, 2-period crossover study. The study consists of a screening visit followed by a treatment period comprising 2 treatment visits. The treatment period visits will be separated by a 4 to 14-day washout period. Eligible patients will be kept overnight prior to each treatment period.


Minimum age: 4 Years. Maximum age: 11 Years. Gender(s): Both.


Inclusion Criteria: 1. Written informed consent/assent signed and dated by the patient and/or parent/caregiver/legal guardian (as appropriate) before conducting any study-related procedure. 2. Male or pre-menarchal female patient 4-11 years of age, inclusive, as of the Screening Visit (SV) 3. Has a documented physician diagnosis of persistent asthma of a minimum of 3 months duration that has been stable for at least 4 weeks prior to the SV. The asthma diagnosis must be in accordance with the National Asthma Education and Prevention Program Guidelines Expert Panel Report 3 (EPR3). 4. Forced expiratory volume in 1 second (FEV1) >80% predicted for age, height and gender and race at the SV based on the pediatric population standards. 5. Any patient being treated with inhaled corticosteroids (ICS) must be on a lowdose regimen (200 mcg or less of fluticasone propionate per day or equivalent), which has been stable for at least 4 weeks prior to the SV and which is expected to be maintained for the duration of the study 6. Has required less than 4 inhalations per week of a rescue bronchodilator (on average) for the 4 weeks preceding the SV 7. Has the ability to withhold inhaled albuterol for at least 72 hours preceding each Treatment Visit (TV).

- Other criteria apply, including must weigh at least 45 pounds

Exclusion Criteria: 1. A known hypersensitivity to albuterol or any of the excipients in the inhaler formulations (lactose, ethanol, etc.) 2. Participation (receiving study drug) 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. Proneness to orthostatic dysregulation, syncope, or blackouts 5. History of a respiratory infection or disorder (including, but not limited to bronchitis, pneumonia, acute or chronic sinusitis, otitis media, influenza) that has not resolved within 2 weeks preceding the SV. 6. History of life-threatening asthma or that is defined for this protocol as an asthma episode that required intubation and/or was associated with hypercapnea, respiratory arrest or hypoxic seizures 7. Any asthma exacerbation requiring systemic corticosteroids within 3 months of the SV. A patient must not have had any hospitalization for asthma within 6 months prior to the SV.

- Other criteria apply.
