  • Liposomal analgesic drug compositions prepared in GMV using an ammonium sulfate gradient
    Patent number: 7357944
    Abstract: Liposomal bupivacaine compositions are prepared using an ammonium sulfate gradient loading procedure, at a pH which prevents precipitation of the drug from the loading solution. Also described are liposome suspensions comprising ‘GMV’ (giant multivesicular) liposomes and methods for their preparation. The liposomal compositions are characterized by high drug-to-lipid ratios and provide long term analgesia.
    Type: Grant
    Filed: February 5, 2004
    Date of Patent: April 15, 2008
    Assignees: New York University, Yissum Research Development, Co
    Inventors: Elijah M. Bolotin, Gilbert J. Grant, Yechezkel Barenholz, Herman Turndorf, Boris Piskoun
