Abstract: A composite enterosorbent has a substrate in the form of a sorbent based on hydrogel of polymethylsiloxane. For the purpose of complex normalization of the intestinal microflora it further comprises a polysaccharide selected from the group including lactulose, inulin, fructooligosaccharides, alginic acid in the form of its pharmaceutically acceptable salts, acacia, pectin, chitosan, lignin. Respectively, the preparation comprises 0.1 to 10 parts by weight of polysaccharides per 1 part by weight of hydrogel of polymethylsiloxane.

Abstract: The inventive method for producing a sorbent consists in adding a strong acid solution to a methylsiliconate sodium (or potassium) solution for obtaining a product, which after being stabilised, is ground and activated by adding a strong acid to the solution, is washed out by water until a neutral reaction is attained in such a way that a product, the pore space of which is equal to or greater that 0.8 cm3/g is obtained, wherein said product exhibits adsorption properties with respect to mean- and high-molecular agents and can contain chemical and/or biological additives. The thus obtained product has a general formula: {(CH3SiO1.5)nH2O}[k1 . . . Km], wherein ki is a mass ratio (mass %) for chemical additives (m?2) or a qualitative characteristic for the content of biological additives; xerogel is produced at n=0; gel form is produced at n=30-46; past form is produced at n=54-62; suspension form is produced at n=63-495.
