  • Patent number: 7041318
    Abstract: The present invention is a method of milling materials to form a fine powder with a median particle size below 10 micrometer which is suitable for inhalation and which has substantially no amorphous content generated during milling. The method is particularly suitable for milling materials which are soft. The method comprises milling the material in a fluid energy mill at reduced temperature using helium, or helium mixed with another gas, as milling fluid. Temperatures of ?30° C. or less are used.
    Type: Grant

  • Patent number: 6641063
    Abstract: The invention is an improved method of generating fine medicament powders suitable for inhalation. A fluid energy mill is used with conventional milling fluids such as air or nitrogen. The milling fluid is treated to have a controlled relative humidity of between 30% and 70%. This produces a fine medicament powder with a median particle size below 10 micrometer but with little or no amorphous content generated during milling. Scale formation in the mill chamber is also greatly reduced.
