Bioequivalence Between Albuterol Sulfate Inhalation Aerosol 108mcg Per Actuation and Proair HFA (Albuterol Sulfate) Inhalation Aerosol 90mcg Per Actuation in Healthy Volunteers Under Fasting Conditions

The primary objective of the study was to assess the bioequivalence between the test product (Albuterol Sulfate inhalation aerosol 108mcg per actuation) and the reference product (Proair HFA \[albuterol sulfate\] Inhalation Aerosol 90mcg per actuation) under fasting conditions. Bioequivalence would be demonstrated if the 90% confidence interval for the ratios of geometric means for AUC(0-t), AUC(0-inf), and Cmax between test products and reference products were completely contained within the FDA defined acceptance range of 80.00%-125.00%.
