  • Method of producing sub-micron particles of biologically active agents and uses thereof
    Patent number: 6428815
    Abstract: Submicron particles of a biologically active agent are prepared by atomizing using multifluid atomization a dispersed system comprising at least one biologically active agent and at least one solvent to produce droplets, freezing the droplets to produce frozen droplets, lyophilizing the frozen droplets to obtain microstructures capable of being further fragmented into submicron particles by techniques such as probe sonication. The submicron particles can be incorporated into sustained release compositions having a reduced initial release of biologically active agent. The sustained release compositions can be administered to a human or animal.
    Type: Grant
    Filed: July 3, 2001
    Date of Patent: August 6, 2002
    Assignee: Alkermes Controlled Therapeutics, Inc.
    Inventors: Henry R. Costantino, Warren E. Jaworowicz, Mark A. Tracy, Christopher P. Beganski
