Tablet comprising at least one biologically active substance and an excipient, in which the excipient contains calcium carbonate and at least one additive selected from fatty acids, their salts, their esters, lipid materials, polysaccharides, polyvinylpyrrolidone and polyvinylpyrrolidone derivatives, acrylic compounds, mono-, di- or triglyceride esters, animal proteins, and mixtures of at least two of these. Method for producing these tablets. Use of calcium carbonate in tablets containing at least one biologically active substance, for the prolonged release of this substance.

Tablets comprising a biologically active substance and an excipient containing calcium carbonate

Compositions of natural, especially plant, constituents in the form of spheroids in particular of the medicinal type and formulations necessary to their preparation by a technical extrusion and spheronization system. Compositions characterized by the direct use of large quantities of solutions of natural, especially plant, origin such as liquid extracts adsorbed by natural or synthetic polymer-type substances. These various components are selected so that their combination permits the obtainment of a mass of a plasticity compatible with the technical extrusion and spheronization system. According to the process, liquid extract is prepared, this extract is incorporated in a substance of a polymeric type, the correctly moistened mass is extruded by micro-extrusion techniques and the extrudates are spheronized and then dried and calibrated.
