Optimized fluorocarbon emulsions for blood substitutes and other therapeutic uses

摘要

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.

主权项

1. A fluorocarbon emulsion comprising: a continuous aqueous phase and a discontinuous fluorocarbon phase, wherein the discontinuous fluorocarbon phase consists of perfluorooctyol bromide and perfluorodecyl bromide, wherein the perfluorooctyl bromide is present in the fluorocarbon emulsion at 57-60% w/v of the total emulsion and the perfluorodecyl bromide is present in the emulsion at 1-3% w/v of the total emulsion.
