Abstract: The invention relates to a method for producing effervescent granules, in which the reaction partners edible, organic acid components and alkaline effervescent components separating carbon dioxide are reacted with each other in a vacuum under the effect of gas in a container that can be evacuated. The container is evacuated to a first vacuum value within a vacuum range of 200-900 mbar, whereupon the pressure inside the container is increased to a second vacuum value as a result of the gases produced during the reaction. The steps are cyclically repeated while the reaction continues. A maximum number of cycles, a maximum reaction time, and optionally, a maximum load for the stirring apparatus are defined before the reaction begins, and the reaction is terminated after reaching the first of the maximums.

Abstract: The soluble, rubber-containing, coated chewable tablet contains chewable components, syrup components and fat or wax components and optionally fillers. It can be prepared by a process in which pulverulent chewable components are mixed with the molten fat or wax components. The mixture, with the addition of at least one syrup component, then becomes a crumbly material, which is then cooled to below 0° C., then milled to a particle size of not more than 5 mm and, after cooling to below 10° C., compressed to give tablets which are coated in a known manner. The finished product—due to compression of the cooled granules—presumably has a partially granular structure in which the moisture has been initially immobilized by the low temperature. After compression, this moisture becomes mobile as a result of heating (in particular during the coating process) and migrates or diffuses—initially at the surface—into the water-soluble ingredients present.

Abstract: The pharmaceutical formulation according to the invention is in the form of instant granules, in which the surface of the particles of at least two different soluble carrier materials is covered or coated with at least one layer which contains -of from 50 to 120, preferably from about 60 to about 100, parts by weight of active substance per 100 parts by weight of carrier material -of at least one, preferably insoluble or slightly soluble, active substance, such as amino acids or antioxidants. A first carrier material constitutes from about 50 to about 80% by weight of the total carrier material and is selected from carrier materials having a bulk density of between 58 and 100, preferably between 63 and 90 g/100 ml, while the second carrier material is selected from carrier materials having a bulk density of between 30 to 55, preferably between 33 and 50 g/100 ml.

Abstract: An uncoated compressed tablet which is used for the preparation of an orally applicable aqueous suspension or solution of a pharmaceutically active substance contains a mixture of the pharmaceutically active substance, a swelling disintegrant and an effervescent system. The weight ratio of the disintegrant to the effervescent system is from 0.1:1 to 4:1.
