Abstract: The present invention concerns a solid, palatable composition and its preparation process which, relative to the total weight of the composition, comprises: 5 to 30%, preferably 8 to 20% by weight of at least one fat chosen from among a liquid oil, a fat, wax or mixture thereof, the liquid oil not to represent more than 8% by weight of the composition; 0.001 to 85% by weight of at least one active substance; and 20 to 95%, preferably 40 to 70% by weight of at least one palatable material, for use thereof as medicinal product, nutraceutical or food supplement, for oral administration to mammals, except man, in particular for domestic animals such as dogs, cats or horses. The said solid composition is obtained by mixing the components, vaporising the fats, calibrating the dry, fluid granular material and compressing the granular material in a stock cube press.

Abstract: The invention relates to a method for the production of a time-stable, solid appetizing composition and to the use thereof, said composition comprising at least one active substance which is introduced in the final production step, by adding same to the already formed mixture of other components at ambient temperature, without the use of water or heat. The composition is intended for use as a drug, a nutraceutical or a food supplement for oral administration to mammals, except humans, in particular for pets such as dogs, cats or horses. The stable solid composition is obtained by compressing the mixture using a press for compressing formulations having a high fat content.

Abstract: Process for the preparation of rifaximin, pseudo-crystalline rifaximin and a new pseudo-crystalline form of rifaximin with fewer impurities obtained thereby.
