ABSTRACT:
Novel hydrocarbon oil/fluorochemical preparations and methods for their use are provided. The preparations, which preferably comprise a fluorophilic dispersing agent, may be in the form of hydrocarbon oil-in-fluorochemical dispersions or in the form of a multiple emulsion comprising a polar liquid continuous phase and are particularly useful for administering bioactive agents. In particular the preparations of the present invention may be used to control the bioavailability and improve the efficacy of lipophilic bioactive agents having limited solubility in an aqueous physiological environment.
