The invention is directed to a process for the preparation of suspensions of drug particles for inhalation delivery, said process providing particles of optimized particle size and distribution homogeneously dispersed in the carrier. The process, which is also suitable for the preparation of sterile suspensions, includes the step of homogenizing and micronizing the formulation in a turboemulsifier provided with a high-potency turbine, optionally followed by a treatment in a high-pressure homogenizer. A further aspect of the invention is directed to a process for preparing micronized sterile beclomethasone dipropionate by gamma-irradiation. |
