  • Publication number: 20100086611
    Abstract: The present invention relates to compositions of submicron- to micron-size particles of antimicrobial agents. More particularly the invention relates to a composition of an antimicrobial agent that renders the agent potent against organisms normally considered to be resistant to the agent. The composition comprises an aqueous suspension of submicron- to micron-size particles containing the agent coated with at least one surfactant selected from the group consisting of: ionic surfactants, non-ionic surfactants, biologically derived surfactants, and amino acids and their derivatives. The particles have a volume-weighted mean particle size of less than 5 ?m as measured by laser diffractometry.

  • Patent number: 7037528
    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 400 nm to 2 microns.

  • Publication number: 20040256749
    Abstract: 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.

  • 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.
