Summary for Patent: 7,833,546
Title: | Pharmaceutical dosage form and method for the production thereof |
Abstract: | The invention relates to a method for producing a pharmaceutical dosage form as tablets, pellets and/or in the form of an active ingredient-containing matrix, whereby the tablets, pellets and/or active ingredient-containing matrix contain a pharmaceutical active ingredient and a copolymer serving as a coating agent and/or binding agent, and optionally contain a core and pharmaceutically common additives. According to the invention, the copolymer, the pharmaceutical active ingredient, the optionally present core and/or the pharmaceutically common additives are processed using known techniques by melting, injection molding, extrusion, wet granulation, casting, dipping, spreading out, spraying on, or pressing to form tablets, pellets and/or an active ingredient-containing matrix. The inventive method is characterized in that a copolymer is used that consists of 20 to 34 wt. % methacrylic acid, 20 to 69 wt. % methylacrylate and 0 to 40 wt. % ethylacrylate and, optionally, of 0 to 10 wt. % of additional vinylically copolymerizable monomers with the provision that the glass transition temperature of the copolymer is no higher than 60.degree. C. according to ISO 11357-2, Item 3.3.3. The invention also relates to the pharmaceutical dosage form produced according to this method, said copolymer and the use thereof. |
