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: A matrix material containing sugars and/or sugar alcohols serves to encapsulate solid or liquid substances, in particular pharmaceutically active substances and/or at least one pharmaceutically admitted flavor and the like. The material contains a substance that during cooling from its melt largely suppresses crystallization of the melt. The substance can be, for example, an inner ester of a hydroxy acid, particularly gluconic acid delta-lactone. The suppression of crystallization can be achieved by adding a small amount of a pharmaceutically admitted, and preferably weak, acid, such as lactic acid or malic acid, that simultaneously reduces the risk of saponification by alkaline components of an effervescent system that might be present.

Abstract: The effervescent base for the preparation of effervescent tablets and effervescent granules consists of at least one acidic and one gas-evolving component, the former of which is formed by a mixture of (predominantly) monosodium tartrate and (possibly) disodium tartrate, and optionally tartaric acid. The effervescent base is prepared by mixing tartaric acid with sodium bicarbonate and sodium carbonate containing water of crystallization and slowly reacting the mixture at a temperature increasing to about 50° C., after which further sodium carbonate containing water of crystallization is admixed and is allowed to react up to a temperature of about 60° C., and drying is then carried out, preferably in vacuo, the mixture is mixed with further, now anhydrous sodium carbonate and the product is optionally pressed to give tablets. The base may additionally comprise an acid sensitive or an alkali-sensitive pharmaceutically active substance.

Abstract: A pharmaceutical formulation includes a hydrophobic active substance, an effervescent system, and at least two surfactants. Each of the surfactants is selected from a different group selected from the following three groups: phospholipids, polysorbates, and esterified sugars. The formulations provide improved dispersion and bioavailability of hydrophobic active substances.

Abstract: A process for producing a granulated material from a powder mixture containing at least two components, one of which is in crystal or crystalline form and at least one contains water of crystallization and/or is reactive, granulation is carried out in an inclined drum. Powder is fed in at one end and granulate removed at the other, after being transported inside the drum for a desired period while the drum is rocked in a way which largely eliminates shear forces. A quantity of liquid at least approximately equal to the quantity of water of crystallization present and sufficient for the formation of a superficially active solution adhesive is released inside the drum, where appropriate by partial reaction of the reactive component(s), after which the powder mixture components are granulated by surface adhesion.

Carrier crystals are, in particular, citric acid, malic acid, tartartic acid, monosodium citrate and/or ascorbic acid. The first layer may contain gluconic acid delta-lactone and is preferably covered with citric acid, malic acid and/or tartaric acid.
