The present invention relates to metoprolol succinate, a new therapeutically active compound, and pharmaceutical preparations comprising this new compound.

Metoprolol succinate

The present invention relates to a process for treating amphoteric amino acids, and/or amphoteric amino acid derivatives in a fluid bed, whereby in order to maintain fluidizing conditions one adds at least 0.2% by weight of a fatty acid, fatty alcohol and/or fat, preferably containing 14.degree.-20.degree. C.

Process for treating amphoteric amino acids

Pharmaceutical composition comprising metroprolol succinate

The present invention relates to a multiple-unit-dose comprising L-dopa as pharmaceutically active compound, whereby the composition provides a release of L-dopa in accordance with a test in accordance with U.S. Pharmacopeia Standards in an artificial gastric juice having a pH of at most 1.2 of at most 20% by weight during 1 hr, and in a phosphate buffer according to the same standard a release of at least 35% by weight during 1 hr, and at least 80% by weight during 3 hrs.

Composition comprising L-dopa

The present invention relates to a novel pharmaceutical composition comprising N-acetyl cysteine, wherein the composition releases N-acetyl cysteine in accordance with the United States Pharmacopea Standards (USP XXI, apparatus 2, 50 rpm) in an artificial gastric juice having pH 1.2 to an extent of less than 30% after 1 hr of exposure, and to less than 45% after 2 hrs of exposure, that it releases N-acetyl cysteine in accordance with the same standard in a phosphate buffer having pH 6.8 after 1 hr (3 hrs of total exposure) of at least 30%, and at most 100%, and in the same phosphate buffer of pH 6.8 after 5 hrs (7 hrs of total exposure) of at least 90%. The invention further comprises a method for treating symptoms as well as a method of preparing the composition.

Pharmaceutical dosage with core of N-acetyl cystein

The present invention relates to a multiple-unit dose composition comprising furosemide as pharmaceutically active compound, whereby the composition gives a release of furosemide in accordance with Dissotest in a buffer having pH 1.5 of at most 4% during hour 1, a release in a buffer having pH 5.5 of at most 7.5% during a consecutive hour (hour 2), a release of furosemide in a buffer having pH 7.5 of at least 65% during a further consecutive hour (hour 3), and a release of furosemide in a buffer having pH 7.5 of at least 90% during a consecutive hour (hour 4).

Diuretic composition

The present invention relates to a process for preparing a rapidly disintegrating core granulate containing a pharmaceutically active compound, which granulate is optionally intended to be coated with a release determining coating, as well as such cores, whereby one adds a pharmaceutically active compound, optionally together with an emulsifier, to a solvent, and optionally treats the composition obtained intensively, optionally while reducing its particle size, distributes the treated composition obtained over a bed of a solid, preferably water soluble material, and dries the agglomerates thus obtained to the so as to form a rapidly disintegrating core granulate.
