  • Patent number: 9119793
    Abstract: The present disclosure relates to dosage forms, e.g., swell, float and bioadhesive, and methods that enhance the absorption of doxycycline in the gastrointestinal tract. The oral dosage forms control the spatial and temporal delivery of doxycycline in the gastrointestinal tract. This controlled spatial and temporal delivery provides a site and rate of release, respectively, of the doxycycline into the gastrointestinal tract that enhances the amount of the doxycycline absorbed into the bloodstream.

  • Patent number: 6126946
    Abstract: A heat and shelf-stable oil-in-water emulsion useful as a tissue or cell-selective delivery vehicle. Radioactive or stable, synthetic or semi-synthetic polyhalogenated triglycerides, such as 2-oleoylglycerol-1,3-bis[7-(3-amino-2,4,6-triiodophenyl)heptanoate] or 2-oleoylglycerol-1,3-bis[.omega.-(3,5-bis-trifluoromethyl)hepatanoate] or phenyl acetate, can be incorporated into the lipophilic core of a lipoprotein-like emulsion particle. The lipophilic core is surrounded by a phospholipid membrane comprising cholesterol and apolipoproteins. For hepatocyte-selective delivery, the emulsion is chylomicron remnant-like by being in a size range of 50 to 200 nm as measured by number weighting analysis with a narrow size distribution (<2% greater than 300 nm) and having a composition simulating naturally-occurring chylomicron remnants. Use of cholesterol in the emulsion formula facilitates association of apolipoproteins, especially Apo E which are recognized by liver cells and necessary for binding and uptake.

  • Patent number: 5851510
    Abstract: A heat and shelf-stable oil-in-water emulsion useful as a tissue or cell-selective delivery vehicle. Radioactive or stable, synthetic or semi-synthetic polyhalogenated triglycerides, such as 2-oleoylglycerol-1,3-bis?7-(3-amino-2,4,6-triiodophenyl)heptanoate! or 2-oleoylglycerol-1,3-bis?.omega.-(3,5-bis-trifluoromethyl)heptanoate! or phenyl acetate, can be incorporated into the lipophilic core of a lipoprotein-like emulsion particle. The lipophilic core is surrounded by a phospholipid membrane comprising cholesterol and apolipoproteins. For hepatocyte-selective delivery, the emulsion is chylomicron remnant-like by being in a size range of 50 to 200 nm as measured by number weighting analysis with a narrow size distribution (<2% greater than 300 nm) and having a composition simulating naturally-occurring chylomicron remnants.
