  • Patent number: 5763422
    Abstract: Disclosed are compositions comprising non-steroid anti-inflammatory drugs (NSAID'S)complexed with zwitterionic or neutral phospholipids and having reduced gastrointestinal irritating effects and enhanced antipyretic analgesic, and antiinflammatory effects. Also disclosed are improved methods of using the complexes for treating fever, inflammation, and preventing platelet aggregation. In some embodiments, the anti-pyretic activity of sub-therapeutically used amounts of NSAID's are enhanced to elicit anti-pyretic activity in vivo when associated (noncovalently) with zwitterionic phospholipids, such as dipalmitoyl phosphatidyl choline.

  • Patent number: 5260287
    Abstract: Compositions and methods for protecting the luminal lining against gastric acid challenge are disclosed. The compositions provide effective anti-ulcer preparations which include phosphorylated alcohol. Phosphorylated alcohols comprise the active anti-ulcerogenic ingredient of the described therapeutic formulations. The preparation of unique linear and cyclic polyphosphorylated alcohols and methods of using same to protect the stomach luminal lining against acid challenge are also disclosed. Inositol hexaphosphate and mannitol hexaphosphate are demonstrated to provide therapeutic value in the treatment and prevention of gastro-erosive disease precipitated by exposure of biological tissues to highly acidic substances, for example, the gastric digestive acids. While inositol hexaphosphate alone at subthreshold concentrations provides a small gastro-protective activity, a combination of inositol hexaphosphate (at subthreshold concentrations) with polyvalent cations, such as Au.sup.+3 or Bi.sup.

  • Patent number: 5260284
    Abstract: The present invention discloses unique methods employing mixtures of phospholipids and neutral lipids for surfactant replacement therapy in the treatment of the various forms of respiratory distress syndrome. These compositions are shown to greatly enhance the surfactant replacement efficiency of surface-active lipids. In this regard, experimental models have shown that both the surface-tension lowering effect and rate of phospholipid absorption to an air/liquid interface are accelerated by the addition of triglycerides and/or sterols to mixtures of saturated or unsaturated phospholipids. Such compositions are therefore theorized to give new and enhanced therapeutic value to the use of surface-active lipids for surfactant replacement therapy in a subject without risk of immunogenic response. The subject methods also comprise a simple, rapid and inexpensive means for the deposition of polar lipids to a variety of air/liquid interfaces.

  • Patent number: 5134129
    Abstract: Disclosed are methods employing compositions composed of unique mixtures of phospholipids and neutral lipids to treat the luminal lining of the gastrointestinal tract in the prevention or treatment of ulcerogenic processes such as peptic ulcer disease and inflammatory bowel disease. Compositions including mixtures of saturated or unsaturated phospholipids, together with saturated or unsaturated triglycerides and/or sterols, are shown to provide a surprising ulcer protective efficacy in experimental models. Further enhancement of activity is found upon the addition of a polyvalent cation or antioxidant to the various lipid mixtures.The present invention also discloses unique methods employing mixtures of phospholipids and neutral lipids for surfactant replacement therapy in the treatment of the various forms of respiratory distress syndrome. These compositions are shown to greatly enhance the surfactant replacement efficiency of surface-active lipids.
