Abstract:
The present invention is a method for preparing micron-sized or submicron-sized drug particles comprising contacting a solution comprising a poorly water soluble drug substance and at least one freezable organic solvent with a cold surface so as to freeze the solution; and removing the organic solvent. The resulting particles are also disclosed, as are several embodiments of an apparatus that can be used in performing the method of the present invention.
