  • Preparation of injectable suspensions having improved injectability
    Publication number: 20080044478
    Abstract: Injectable compositions having improved injectability. The injectable compositions include microparticles suspended in an aqueous injection vehicle having a viscosity of at least 20 cp at 20° C. The increased viscosity of the injection vehicle that constitutes the fluid phase of the suspension significantly reduces in vivo injectability failures. The injectable compositions can be made by mixing dry microparticles with an aqueous injection vehicle to form a suspension, and then mixing the suspension with a viscosity enhancing agent to increase the viscosity of the fluid phase of the suspension to the desired level for improved injectability.
    Type: Application
    Filed: July 19, 2007
    Publication date: February 21, 2008
    Applicant: Alkermes Controlled Therapeutics, Inc.
    Inventors: J. Ramstack, M. Gary Riley, Stephen Zale, Joyce Hotz, Olufunmi Johnson
