  • Biodegradable microparticle pharmaceutical formulations exhibiting improved released rates
    Patent number: 9693967
    Abstract: This invention is directed to an apparatus and method for producing microparticles comprising pharmacologically active agents and biodegradable polymers. The apparatus includes a spinning disk containing a reservoir in the center thereof and a flat inclined surface. The apparatus optionally includes serrations and/or a flat surface beneath the periphery of the disk that is parallel to the rotational axis of the disk. The invention is also directed to a method for producing microparticles containing pharmacologically active agents, using the spinning disk apparatus. Formulations containing ophthalmically active agents are provided. Formulations exhibiting zero order release rates are also described.
    Type: Grant
    Filed: September 7, 2005
    Date of Patent: July 4, 2017
    Assignee: SOUTHWEST RESEARCH INSTITUTE
    Inventors: Joseph T. Persyn, Joseph A. McDonough, Neal K. Vail, Darren E. Barlow, Albert M. Zwiener, Eliot M. Slovin
