  • Methods of processing compositions containing microparticles
    Patent number: 8367427
    Abstract: A method for processing multi-phasic dispersions is provided. The method comprises providing a multi-phasic dispersion including dispersed and continuous phases, providing one or more non-solvents comprising an aqueous solution containing at least one multivalent cation, exposing the multi-phasic dispersion to the non-solvent to form a suspension containing one or more liquid phases and the solid microparticles, and removing at least a portion of the resulting one or more liquid phases while retaining at least the microparticles, thereby removing at least a portion of the non-volatile material from the microparticles.
    Type: Grant
    Filed: August 20, 2008
    Date of Patent: February 5, 2013
    Assignees: Baxter International Inc., Baxter Healthcare S.A.
    Inventors: Ramin Darvari, Adam Lambert, Julia E. Rashba-Step, Mark X. Yang, Junhong Zhang, Ed O'Connell

  • Non-covalent modification of microparticles and process of preparing same
    Publication number: 20100009007
    Abstract: The present disclosure is directed to surface-modified microparticles, pharmaceutical compositions thereof, and methods of making and using such particles. The surface-modified microparticles include a microparticle core, and at least one monolayer associated with the microparticle core. The monolayer comprises an amphiphilic polymer or non-ionic polymer grafted to an ionic polymer.
