  • Method for preparing submicron suspensions with polymorph control
    Publication number: 20030044433
    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 presuspension.
    Type: Application
