Publication number: 20040256749Abstract: The present invention is concerned with the formation of small particles of an organic compound by mixing a solution of the organic compound dissolved in a water-miscible organic solvent with an aqueous medium to form a mix and simultaneously homogenizing the mix while continuously removing the organic solvent to form an aqueous suspension of small particles essentially free of the organic solvent. These processes are preferably used to prepare an aqueous suspension of small particles of a poorly water-soluble, pharmaceutically active compound suitable for in vivo delivery by an administrative route such as parenteral, oral, pulmonary, nasal, buccal, topical, ophthalmic, rectal, vaginal, transdermal or the like.Type: ApplicationFiled: October 29, 2003Publication date: December 23, 2004Inventors: Mahesh Chaubal, Mark J.

Publication number: 20040022862Abstract: 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.Type: ApplicationFiled: March 17, 2003Publication date: February 5, 2004Inventors: James E.
