Aerodynamic particle size distribution from BGF MDIs. Comparison of budesonide, glycopyrrolate, and formoterol fumarate aerodynamic particle size distribution from non-radiolabeled BGF MDIs and radiolabeled BGF MDIs used in this study. The effective cut-off particle size for each stage is shown for an inhalation flow rate of 30 L/min.
