SUBSTANCE: invention relates to nateglynide-containing preparation used in treatment of diabetes mellitus that comprises nateglynide as an active component and a carrier wherein nateglynide in amorphous form and indicated carrier represents hydrophilic material. Amorphous property of crystalline nateglynide is provided by the following methods: 1) by dissolving nateglynide crystals in pharmacologically acceptable solvent in common with hydrophilic materials taken among the group consisting of water-soluble polymers, water-swelling polymers, sugar alcohols and salts followed by granulation in fluidized layer, granulation by stirring at high rate, drying by spraying and process for coat applying for granulation of amorphous nateglynide; 2) by mixing nateglynide crystals with hydrophilic materials taken among the group of water-soluble polymers, water-swelling polymers, sugar alcohols and salts and the following application of the high shift force to the prepared mixture; 3) by mixing nateglynide crystals with hydrophilic materials taken among the group of water-soluble polymers, water-swelling polymers, sugar alcohols and salts and the following plasticizing the prepared mixture in melt by heating and milling at cooling; 4) by dissolving nateglynide crystals in pharmacologically acceptable liquid additives wherein liquid additives represent water-soluble polymers that are liquid at 37°C. Using amorphous nateglynide allows preparing the nateglynide preparation with immediate release wherein the dissolving rate of medicinal agents is high and without crystalline transition during preparing or preserving preparations.

EFFECT: valuable pharmaceutical properties of preparation.
