  • Publication number: 20120207762
    Abstract: Stable pharmaceutical formulations and methods of making same are provided. In a general embodiment, the present disclosure provides a method of making a stable pharmaceutical formulation comprising adding one or more vitrifying additives to an aqueous pharmaceutical solution to raise the glass transition temperature of the aqueous pharmaceutical solution. The aqueous pharmaceutical solution can be cooled to a temperature of about ?50° C. to about ?10° C. The vitrifying additive enhances the formation of a glass or amorphous solid of the aqueous pharmaceutical solution at cryogenic temperatures (?50 to ?10° C.), and the pharmaceutical formulation can be thawed to liquid form and administered to a mammalian subject.

  • 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.

  • Publication number: 20090152176
    Abstract: The disclosure describes apparatuses and methods of use that may be used to remove material with magnetic properties from compositions, particularly pharmaceutical compositions. The apparatuses provide a conduit or column in which a magnetic field exists and through which a composition flows. Magnetic material in the composition is substantially reduced after flowing through the conduit or column.

  • Patent number: 7511079
    Abstract: Methods and apparatuses for comminuting and stabilizing small particles are provided. In one embodiment, an apparatus moves an organic compound dissolved in a solvent to form a suspension of particles in a first fluid stream and moves the suspension in a second fluid stream, wherein the second fluid stream is oriented and positioned with respect to the first stream to cause shearing between the streams and mixing of at least some of the particles in the first and second streams.

  • Patent number: 6884436
    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 pre-suspension.
