  • Patent number: 8557286
    Abstract: The invention relates to a method for producing pharmaceutical forms or preliminary stages thereof by means of extrusion. The pharmaceutical form has a matrix which the active agent is contained essentially, and whose essential characteristics are determined by the extrusion process and which comprises a polysaccharide and/or derivative thereof and/or a complex thereof and/or any mixture of the aforementioned substances with other substances and/or saccharides and/or derivatives thereof as an essential constituent, and at least one pharmaceutically active substance.
    Type: Grant
    Filed: April 20, 2000
    Date of Patent: October 15, 2013
    Assignee: EuroCeltique, S.A.
    Inventors: Hubert Rein, Klaus-Jurgen Steffens
  • Patent number: 7756248
    Abstract: Angle dispersive X-ray diffraction is used to test pharmaceutical products including a dosage form inside packaging, for example a tablet inside a blister pack, without removing the dosage form from the packaging. The dosage form is aligned with a measurement system having an X-ray source for generating X-rays, X-ray optics, and an X-ray detector for detection of X-rays. Then, at least one X-ray signature is measured on a predetermined location on the dosage form. The measured X-ray signature is compared with reference X-ray signatures in a data library.
    Type: Grant

  • Patent number: 7208175
    Abstract: Rapidly disintegrating preparations containing at least one active pharmaceutical ingredient and at least one excipient can be obtained by a simple process in which at least the predominant part of the complete composition of the ingredients for the preparation to be produced is granulated, the resulting granules and, where appropriate, the remainder of the ingredients are shaped in the presence of liquid virtually without pressure, and the resulting shaped articles are dried.

    Assignee: Bayer Ag
    Inventors: Marco Schroeder, Klaus-Jürgen Steffens
  • Patent number: 6900246
    Abstract: A method for generating an aerosol includes the step of guiding a gas which flows at supersonic velocity and which has input particles suspended therein in such a way that a compression shock occurs. The input particles are broken down into smaller output particles upon crossing the compression shock. A device for generating an aerosol is also provided.

  • Patent number: 4801455
    Abstract: A pharmaceutical formulation for the parenteral, in particular intravenous, administration of sparingly soluble substances is obtained when the very finely ground substance, with a maximum particle diameter of 3 .mu.m, is dispersed in an oil phase which contains emulsifier, and this mixture is emulsified with water for injection, is rendered isotonic and is homogenized using a high-pressure homogenizer, so that the resultant product is a solid/liquid/liquid disperse system.
