  • Multiphase active ingredient-containing formulations
    Patent number: 6787157
    Abstract: A solid or semisolid, at least two-phase active ingredient-containing formulation in which there is multiparticulate incorporation of one of the two phases into a matrix of the other phase, and at least one of the phases contains at least one active ingredient, obtainable by introducing particles of one phase into the other phase in a plastic state, and shaping the material while still plastic.

  • Cleavable solid dosage forms and method for the production thereof
    Patent number: 6488939
    Abstract: Solid, elongate dosage forms (10) with a long axis (11) and with a length (L) which is defined by projection of the ends (12, 13) of the dosage form to the long axis, where a cross-sectional area (14, 15, 16) oriented perpendicular to the long axis (11) has an area which is variable along the long axis (11) and increases from a cross-sectional area (15) which is located between the ends (12, 13) and has a minimal area essentially continuously toward the two ends (12, 13) up to in each case a cross-sectional area (14 and 16 respectively) with a maximal area, wherein the distance of the maximal cross-sectional area (14) which is located near one end (12) from the maximal cross-sectional area (16) which is located near the other end (13) is, projected on the long axis (11), more than half the length (L) of the dosage form (10), are described.

  • Solid medicaments obtained by extrusion of an isomalt-containing polymer-active substance melt
    Patent number: 6187342
    Abstract: The invention relates to solid drug forms obtainable by extrusion with subsequent shaping of a solvent-free melt, comprising, besides one or more active ingredients, A) 10-90% by weight of a melt-processable, water-soluble polymer, B) 5-85% by weight of isomalt, and C) 0-5% by weight of lecithin, where the total of all the ingredients is to be equal to 100% by weight.
