  • Patent number: 9192679
    Abstract: The invention relates to a novel galenical system for taste masking, protecting an active substance, in particular in an acid medium, modulating releasing properties, masking mucous irritability and toxicity of certain active substances, for preparing aqueous forms which have a masked taste, are stable and pH independent. Said invention also relates, in particular to a galenical system which is embodied in the form of lipidic solid particles and strictly hydrophobic and devoid of water, surface active agents, emulsifiers, solvent traces and which is characterized in that it comprises at least one type of hydrophobic wax and at least one type of fatty non-neutralised acid.

  • Publication number: 20100086595
    Abstract: The present invention concerns a novel hydrophobic galenic system allowing improved masking of the taste of the active ingredients it contains, the stability of said active ingredients and, when applicable, sustained release thereof. The galenic system of the invention consists of lipid particles with no surfactants or emulsifiers, comprising a lipid hydrophobic matrix that is non-ionizable at physiological pH in which the active ingredient(s) are dispersed. This system is suitable for the preparation of pharmaceutical or veterinary compositions, in particular for administration via oral route or via injection.

  • Patent number: 6346263
    Abstract: The present invention relates to a particulate biodegradable matrix comprising a biodegradable and hydrophilic core with a base of carbohydrate or polyol or polyamine matrix, cross-linked and derived in the mass by variable amounts of ionic groups; a hydrophilic polymer layer associated with the central core by chemical, for example ionic, interaction; and surface molecules or polymers grafted on the external polymer layer by covalent bonds.

  • Patent number: 5968794
    Abstract: A biodegradable particulate vector for transporting biologically active molecules is prepared containing a nucleus formed of a cross-linked polysaccharide or oligosaccharide matrix having grafted ionic ligands, a layer of fatty acid compounds covalently bonded to the nucleus and a layer of phospholipids hydrophobically bonded to the layer of fatty acid compounds. Dextran, cellulose or starch may be cross-linked with epichlorohydrin to form a cross-linked polysaccharide matrix. Ionic ligands may be grafted using an acidic compound such as succinic acid, phosphoric acid or phosphorous oxychloride, or a basic compound such as choline, hydroxycholine, 2-(dimethylamino)ethanol or 2-(dimethylamino) ethylamine fastened onto the grafted acidic compound. Phosphoric acid or phosphorous oxychloride in one step provide both cross-linking and ionic ligands. Co-cross-linking can be obtained using a protein such as keratin, collagen or elastase.

  • Patent number: 5736371
    Abstract: A biodegradable particulate vector for transporting biologically active molecules is prepared containing a nucleus for containing a biologically active molecule, a first layer of fatty acid compounds covalently bonded to the nucleus and a second layer of phospholipids hydrophobically bonded to the first layer. The nucleus is between 10 nm and 10 .mu.m in size and is formed of a cross-linked polysaccharide or oligosaccharide matrix onto which ionic ligands are uniformly grafted. The cross-linked polysaccharide may be dextran, cellulose or starch cross-linked with epichlorohydrin. The ligand may be an acidic compound selected from succinic acid, phosphoric acid, citric acid, glycine, alanine, glutamic acid and aspartic acid, or a basic compound such as choline, hydroxycholine, 2-(dimethylamino)ethanol or 2-(dimethylamino)ethylamine fastened onto the matrix via the acidic compound. The polysaccharide or oligosaccharide may be co-cross-linked with a protein such as keratin/collagen or elastase.
