Patent number: 7438929Abstract: 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.Type: GrantFiled: September 27, 2004Date of Patent: October 21, 2008Assignee: Roehm GmbH & Co.

Publication number: 20070243247Abstract: 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.Type: ApplicationFiled: May 12, 2005Publication date: October 18, 2007Inventors: Jennifer Dressman, Hans-Jürgen Stein, Thomas Furst, Christiane Bott
