  • Preparation of submicron solid particle suspensions by sonication of multiphase systems
    Publication number: 20060003012
    Abstract: The present invention provides a method for preparing submicron-sized particles. The method includes the steps of: (1) providing a multiphase system having an organic phase and an aqueous phase, the organic phase having a pharmaceutically effective compound therein; and (2) sonicating the system to evaporate a portion of the organic phase to cause precipitation of the compound in the aqueous phase and having an average effective particle size of less than about 2 m.
    Type: Application
