  • Optimized fluorocarbon emulsions for blood substitutes and other therapeutic uses
    Patent number: 8748497
    Abstract: The present invention is directed to a stable fluorocarbon emulsion having a continuous aqueous phase and discontinuous fluorocarbon phase comprising two fluorocarbons and surprisingly demonstrates that perfluorodecyl bromide is as effective in stabilizing perfluorooctyl bromide emulsions of certain concentrations than much more highly concentrated perfluorooctyl bromide/perfluorodecyl bromide emulsions without the significant problems experienced in higher concentrated emulsions such as longer organ retention times, formation of PFDB crystals, larger emulsion particles, manufacturing problems and inability of repeat dosing inherent with higher concentrations of perfluorodecyl bromide.
    Type: Grant

    Date of Patent: June 10, 2014
    Assignee: Alliance Pharmaceutical Corp.

  • Patient oxygenation using stabilized fluorocarbon emulsions
    Publication number: 20050256211
    Abstract: Storage stable fluorocarbon emulsions having a continuous aqueous phase and a discontinuous fluorocarbon phase, in which the fluorocarbon phase comprises a major amount of a first fluorocarbon or fluorocarbon mixture, and a minor amount of a second fluorocarbon or fluorocarbon mixture, in which the second fluorocarbon has a molecular weight greater than that of the first fluorocarbon and the second fluorocarbon includes a lipophilic moiety in its structure, whereby the second fluorocarbon serves to promote particle size stability in the emulsion while simultaneously providing favorably short organ retention times when administered to animals in vivo.
