  • Publication number: 20140030336
    Abstract: A pharmaceutical composition for the treatment or acute disorders is described. The composition comprises an essentially water-free, ordered mixture of at least one pharmaceutically active agent in the form of microparticles which are adhered to the surfaces of carrier particles which are substantially larger than the particles of the active agent or agents, and are essentially water-soluble, in combination with the bioadhesion and/or mucoadhesion promoting agent. The invention also relates to a method for preparing the composition and to the use of the composition for the treatment of acute disorders.

  • Publication number: 20130017263
    Abstract: An oral pharmaceutical dosage form comprises pharmacologically effective amounts of an acid-susceptible proton pump inhibitor and an H2 receptor antagonist in combination with at least on pharmacologically acceptable excipient which causes a delayed release and/or an extended release of the proton pump inhibitor. The H2 receptor antagonist is included in the dosage form in such a way that it is rapidly released after administration. This dosage form is suitable for the treatment of conditions associated with an excessive secretion of gastric acid and provides a suitable combination of a rapid onset and a long-lasting duration of the effect. The invention also relates to a method for manufacturing such a dosage form and to a method for the treatment of conditions associated with the secretion of gastric acid.
