The inventive medicinal agent comprises antibodies against beta-subunit of insulin receptor in an activated form produced by means of repeated serial dilution and an external action performed according to homeopathic technology. The inventive method for producing a solid medicinal formulation for perorally treating fatness, diabetes, and other diseases associated with impaired glucose tolerance, consists in mixing the effective amount of carrier, which is showered in a fluidised layer by a water-alcohol dilution of antibodies in the form active against the beta-subunit of the insulin receptor produced by combining the repeated serial dilution, thereby reducing the concentration of antibodies, and an external action according to homeopathic technology, and is dried at a temperature equal to or less than 35°C, with pharmaceutically acceptable additives and in subsequently pelleting the mixture thus obtained by means of direct dry compression.
