  • Publication number: 20180256606
    Abstract: The invention relates to a multilayer dosage form comprised of: a) a neutral core; b) an inner coating consisting of a methacrylate copolymer; c) an outer coating consisting of a copolymer of which 40 to 95% by weight is composed of radically polymerized C1 to C4 alkyl esters of acrylic acid or of methacrylic acid and of which 5 to 60% by weight is composed of (meth)acrylate monomers having an anionic group in the alkyl radical.

  • Publication number: 20090011007
    Abstract: The invention relates to a pharmaceutical composition comprising a mixture of at least one cationic, water-soluble (meth)acrylate copolymer, at least one water-insoluble polymer and at least one active ingredient having a solubility in demineralized water of 3.3 g/l or less, characterized in that the water-insoluble polymer and the active ingredient are present in a ratio of at most 3.5 to 1 parts by weight, and the pharmaceutical composition has the property of releasing the active ingredient present in a medium buffered to pH 1.2 in dissolved form in a concentration which, after 2 hours at pH 1.2, corresponds to at least sixteen times the solubility value of the active ingredient alone at pH 1.2.

  • Patent number: 7438929
    Abstract: The invention relates to a multiparticulate drug form suitable for uniform release of an active pharmaceutical ingredient in the small intestine and in the large intestine, comprising at least two forms of pellets A and B which comprise an active pharmaceutical ingredient in the core and have different polymer coatings which determine the release of the active ingredient at different pH values, characterized in that pellet form A is provided with an inner polymer coating which enables continuous release of active ingredient, and has an outer enteric coating which rapidly dissolves above about pH 5.5, and pellet form B is provided with a polymer coating which, in the USP release test, releases less than 20% of the active ingredient at pH 6.8 in 6 hours and releases more than 50% of the active ingredient at pH 7.2 in 6 hours. The invention additionally relates to a process for producing the multiparticulate drug form and to the use of pellet forms A and B for producing the drug form.

  • Publication number: 20070243247
    Abstract: The invention relates to a dosage form, containing the active ingredient cholylsarcosine, in the form of pellets, which are provided with a polymer coating that is resistant to gastric juices. The invention is characterised in that it discloses pellets comprising an active ingredient, which contain between 50 and 80 wt. % of the active ingredient cholylsarcosine and between 50 and 20 wt. % of one or more conventional pharmaceutical adjuvants as binding agents, whereby at least 90 wt. % of said adjuvants are water-soluble and the size of at least 80 % of the pellets comprising an active ingredient is between 800 and 2,500 $g(m)m. The granulates containing an active ingredient are coated with an anonic, film-forming polymer coating agent, which dissolves in a 0.07M sodium phosphate buffer with a pH value of 5.5 at a dissolution rate of at least 10 mg/min*g and whose dissolution rate in a 0.07M sodium phosphate buffer with a pH value of 6.0 is at least 200 mg/min*g.
