The emulsions comprise a highly fluorinated organic compound, an oil that is not substantially surface active and not significantly soluble in water, a surfactant and water.Type: GrantFiled: May 15, 1995Date of Patent: November 4, 1997Assignee: HemaGen/PFCInventors: Leland C. Clark, Jr., Robert Francis Shaw

Patent number: 5670495Abstract: This invention is directed to a method of attenuating or preventing the adverse side-effects of a perfluorochemical (PFC) emulsion on the hemostatic system and serum chemistry of an animal. The method includes intravenously administering a corticosteroid to an animal prior to intravenous administration of a PFC emulsion, in an amount sufficient to improve the adverse effects of the PFC upon the hemostatic system and serum triglyceride/enzyme levels of the animal. After administration of the corticosteroid, the PFC emulsion is administered intravenously. Preferably, the corticosteroid is dexamethasone, and the PFC is perfluorodichlorooctane.Type: GrantFiled: April 25, 1996Date of Patent: September 23, 1997Assignee: HemaGen/PFCInventors: Thomas H. Goodin, Robert J. Kaufman

Patent number: 5480914Abstract: Nonaqueous thixotropic drug delivery vehicles for use in aqueous physiological systems are disclosed comprising a substantially homogeneous dispersion of at least one suspending aid in a nonaqueous perfluorocarbon or fluorinated silicone liquid carrier. Pharmaceutical compounds may be incorporated to provide thixotropic pharmaceutical compositions having improved delivery profiles and high drug localization. The thixotropic compositions act as free-flowing, drop-instillable liquids upon the application of stress yet behave as a visco-elastic material when at rest. Due to these thixotropic properties the pharmaceutical compositions have improved bioavailability, are capable of low dose volume delivery, and do not degrade the incorporated therapeutic or diagnostic compounds making them well suited for multidose packaging and administration.Type: GrantFiled: May 6, 1994Date of Patent: January 2, 1996Assignee: Allergan, Inc.Inventor: David L.
