FIELD: chemistry.SUBSTANCE: group of inventions relates to a composite organic substance powder for use in medicine, a suspension for use in medicine in which the composite powder is dispersed in water and a method producing the composite powder. In the composite powder, the surface of particles of a poorly water-soluble crystalline organic substance are partially or completely coated with a carboxyvinyl polymer and the average diameter of particles coated with the carboxyvinyl polymer, obtained by calculating the BET specific surface is in the range of 50-400 nm. The method of producing the composite powder includes mixing a poorly water-soluble crystalline organic substance powder, a physiologically acceptable salt, a physiologically acceptable polyol and a carboxyvinyl polymer, pulverising the organic substance powder and removing the salt and the polyol after the pulverisation.EFFECT: invention enables to obtain a medicinal preparation with a low degree of contamination with a pulverisation medium and with improved bioavailability.6 cl, 8 dwg, 2 tbl, 38 ex |
