    摘要: A novel method for the preparation of a tablet comprising a calcium-containing compound, the method involves a melt granulation process by which a sugar alcohol is melted and embeds the calcium-containing compound so that a sufficient taste masking of the chalkiness is substantially achieved and an unpleasant mouth feel of the calcium-containing compound is substantially avoided, while at the same time obtaining a low tablet volume. The method of the invention is especially suitable for the manufacturing of tablets having a high load of a calcium-containing compound.

    摘要: The present invention relates to an oral modified release pharmaceutical composition for the administration of a therapeutically and/or prophylactically effective amount of an active substance (a drug substance) to obtain a relatively fast or quick onset of the therapeutic and/or prophylactic effect. The drug substances contained in a modified release pharmaceutical composition according to the invention are suitably a drug substance which has a very low solubitity under acidic conditions, i.e. under conditions similar to those present in the stomach and/or drug substances which have a pKa value below about 5.5 such as in a range of from about 4 to about 5. The composition is based on a powder comprising a therapeutically and/or prophylactically active substance and has such a particle size that: when the powder is subjected to a sieve analysis, then at least about 90% w/w of the particles passes through sieves 180 μm and the powder is contacted with an aqueous medium to form a particulate composition, which has such a particle size that when the particulate composition is subjected to a sieve analysis, then at least about 50% w/w of the particles passes through sieve 180 μm. Furthermore, the composition, when tested in accordance with the dissolution method (I) defined herein employing 0.07 N hydrochloric acid as dissolution medium, releases at least about 50% w/w of the active substance within the first 20 min of the test.

    摘要: The present invention relates to a novel process for the preparation of a granulate comprising a calcium-containing compound as an active substance. The method comprises a method for the preparation of a granulate comprising a calcium-containing compound as an active substance, the method comprising, i) feeding a granulation chamber with a composition comprising the calcium-containing compound, ii) wet-massing the composition with a granulation liquid optionally comprising a pharmaceutically acceptable binder for a time period of at the most 30 sec to obtain a wet granulate, iii) drying the thus obtained wet granulate. A granulate obtained by the present method is especially suitable in the preparation of solid dosage forms, in particular in the preparation of tablets.
