  • 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.

  • Patent number: 6951656
    Abstract: The present invention provides a method for preparing submicron sized particles of an organic compound, the solubility of which is greater in a water-miscible first solvent than in a second solvent which is aqueous, the process including the steps of: (i) dissolving the organic compound in the water-miscible first solvent to form a solution, (ii) mixing the solution with the second solvent to define a pre-suspension; and (iii) adding energy to the pre-suspension to form particles having an average effective particle size of less than about 2 ?m.

  • Publication number: 20050170002
    Abstract: The present invention provides a method for preparing a suspension of a pharmaceutically-active compound, the solubility of which is greater in a water-miscible first organic solvent than in a second solvent which is aqueous. The process includes the steps of: (i) dissolving a first quantity of the pharmaceutically-active compound in the water-miscible first organic solvent to form a first solution; (ii) mixing the first solution with the second solvent to precipitate the pharmaceutically-active compound; and (iii) seeding the first solution or the second solvent or the pre-suspension.

  • Publication number: 20040022862
    Abstract: The present invention is concerned with the formation of small particles of organic compounds by precipitating the organic compounds in an aqueous medium to form a pre-suspension followed by adding energy to stabilize a coating of the particle or to alter the lattice structure of the particle. The process includes the steps of: (i) dissolving the organic compound in the water-miscible first solvent to form a solution; (ii) mixing the solution with the second solvent to define a presuspension of particles; and (iii) adding energy to the presuspension to form a suspension of particles having an average effective particle size of less than about 100 &mgr;m. The process is preferably used to prepare a suspension of small particles of a poorly water-soluble, pharmaceutically active compound suitable for in vivo delivery by an administrate route such as parenteral, oral, pulmonary, nasal, buccal, topical ophthalmic, rectal, vaginal, transdermal or the like.
