Abstract:
A crystalline salt of 2-[(1R)-3-[bis(l-methylethyl)amino]-1-ρhenylρropyl]-4-methyl-phenol with (2R,3R)-2,3-dihydroxybutanedioic acid, known under the name R-tolterodine tartarate, wherein: a) at least 90 % of all crystals are present in a size smaller than 30 μm, b) at least 40 % of crystalline matter are smaller than 250 μm, c) the maximum size of crystals does not exceed 800 μm, d) the salt contains less than 0.1 weight % of the undesirable enantiomer S-tolterodine tartarate, e) analytical test for sulfate ashes (Pharm. Eur.) provides a value lower than 0.1%. The method of its preparation involves at least one crystallization from water. A pharmaceutical composition containing tolterodine or its pharmaceutically acceptable salts further contains a filler, a disintegrant and a lubricant, said composition being free of ions of alkaline earth metals.
Abstract:
A pharmaceutical composition containing the active substance atorvastatin in the form of oblong-shaped tablets with the length of 5 to 22 mm and the width of 2 to 11 mm or round tablets with the diameter of 3 to 16 mm, the core of which is constituted of compressed granulate and contains: i. Atorvastatin and/or at least one physiologically acceptable salt thereof in the quantity of 5 to 10% by weight, related to pure atorvastatin; ii. An organic or inorganic base selected from meglumine or an alkali metal hydroxide or their combination in the quantity of 0.01 to 7% by weight; iii. A pharmaceutically acceptable filler in the quantity of 20 to 90% by weight; iv. A disintegrant in the quantity of 0.5 to 50% by weight; provided with a coat that makes up 1 to 15% of the weight of the core, the selected base being uniformly distributed in the tablet core by means of spraying the same on the solid mixture in the granule production process. The composition can be obtained by a procedure consisting of the following steps: i. Mixing a mixture of atorvastatin, a filler and a disintegrant; ii. Dissolving a base in a mixture of water and a C 1 to C 3 alcohol in the quantity of 10 : 90 to 90 : 10 (water/alcohol, by weight); iii. Spraying the dry mixture with the base solution either in a masticating or fluidizing device; iv. Adapting the size of particles of the resulting granulate, preferably by re-sieving to the granule size of 0.1 to 1.5 mm; v. Adding other extragranular components to the granulate that will further improve its ability to be compressed into tablets; vi. Compressing the mixture; and vii. Applying a coat on the compressed tablets.
Abstract:
Method of manufacture of compressed pharmaceutical formulation with the active substance tibolone by direct compression into tablets, whereas during the manufacturing process the formulation is subjected to the action of a protic solvent, either by addition of 0.1 to 3% by weight of said solvent in the liquid state and/or in the vapor form by ensuring the ambient atmosphere with the contents of solvent vapors above 50% relative.

Abstract:
A composition containing the active substance telmisartan, which consists of granules of a telmisartan mixture, in which there is the active substance in the form of alkali salts, further contained is an organic or inorganic base selected from meglumine, sodium or potassium hydroxide, or a mixture of said bases, a binder, most preferably polyvinylpyrrolidone, sorbitol, and optionally other auxiliary substances; the composition further containing, outside the granules, particles of sorbitol, and optionally of other auxiliary substance, the size of 99 % by\ weight of all particles of the telmisartan mixture being smaller than 1.0 mm and the size of 95 % by weight of all particles of sorbitol contained in the composition inside as well as outside the granules of the telmisartan mixture being within the range of 0 to 0.250 mm.
