ABSTRACT:
Carrier particles, for use in the preparation of powdery mixtures for administration by inhalation, and having a median diameter of greater than 90 microns and a surface rugosity expressed as the fractal dimension of less than or equal to 1.1, may be prepared by subjecting particles having a median diameter of greater than 90 microns to repeated stages of wetting with a solvent and drying.
