Publication number: 20190224584Abstract: The instant disclosure provides a process for making spray dried compositions and a spray drying apparatus. A relatively small, compound spray dryer is provide with an appropriately sized aspect ratio of height to diameter to allow sufficient drying time for typically sized spray dried dispersion particles intended for solid dosage form applications. The dryer is further designed to provide an amount of drying recirculation that serves to rapidly mix incoming hot drying gas to eliminate hot regions on the dryer walls.Type: ApplicationFiled: September 15, 2017Publication date: July 25, 2019Applicant: Capsugel Belgium NVInventors: Daniel E. Dobry, Richard F. Falk, III, Philip Glover, Travis L. Harrer, Hannah M. Sullivan

Patent number: 9757464Abstract: Pharmaceutical compositions are provided comprising an active agent and a dextran polymer derivative. The compositions include from 0.01 to 99 wt % of an active agent and from 1 to 99.99 wt % of a dextran polymer derivative. The dextran polymer derivative is selected from dextran acetate, dextran propionate, dextran succinate, dextran acetate propionate, dextran acetate succinate, dextran propionate succinate, dextran acetate propionate succinate, and mixtures thereof.Type: GrantFiled: February 12, 2014Date of Patent: September 12, 2017Assignee: Bend Research, Inc.Inventors: Warren K. Miller, David T. Vodak, Daniel E. Dobry, David K. Lyon, Dwayne T. Friesen, Michael M. Morgen, Corey J. Bloom, Daniel T. Smithey

Patent number: 9358478Abstract: A spray-drying apparatus includes a drying chamber that has a first end, a second end, and at least one side wall extending between the first and second ends to define an interior of the drying chamber having a center axis. A nozzle can be positioned at the first end of the drying chamber and be configured to atomize liquid and spray the atomized liquid into the interior of the drying chamber at a maximum spray pattern angle relative to the center axis. A heating device can be provided to heat the liquid prior to introduction into the drying chamber.Type: GrantFiled: June 12, 2015Date of Patent: June 7, 2016Assignee: Bend Research, Inc.Inventors: Daniel E. Dobry, James M. Mullin, Douglas L. Millard, Dwayne T. Friesen, David D. Newbold, John M. Baumann, Devon B. Dubose
