Definitions

  • the present invention relates to solid pharmaceutical preparations of amphiphilic copolymers and sparingly water-soluble active ingredients in combination with surfactants, which are able to influence the stability of the formulation and / or the release of the active ingredients.
  • Solubilization is understood to mean the solubilization of substances which are soluble or insoluble in a particular solvent, in particular water, by surface-active compounds, the solubilizers. Such solubilizers are able to convert poorly water-soluble or water-insoluble substances in clear, at most opalescent aqueous solutions, without this undergoes a change in the chemical structure of these substances.
  • solid solution refers to a state in which a substance is dispersed colloidally or, ideally, molecularly dispersed in a solid matrix such as a polymer matrix .
  • solid solutions for example, when used in solid pharmaceutical dosage forms of a poorly soluble drug to an improved release of the drug.
  • An important requirement of such solid solutions is that they are stable even when stored for a long time, ie, that the active ingredient does not crystallize out.
  • the capacity of the solid solution in other words the ability to form stable solid solutions with the highest possible active ingredient contents, is of importance.
  • WO 2007/051743 discloses the use of water-soluble or water-dispersible copolymers of N-vinyllactam, vinyl acetate and polyethers as solubilizers for pharmaceutical, cosmetic, food-processing, agro-technical or other technical applications. Therein it is generally described that the corresponding graft polymers can also be processed in the melt with the active ingredients.
  • the object of the present invention was to find an improved process and thus improved preparations of substances which are sparingly soluble in water and which, with good bioavailability, enable a stable suspension of the release.

  • the preferred polyalkylene glycols also include those which are alkylated at one or both OH end groups.
  • Suitable alkyl radicals are branched or unbranched C to C22-alkyl radicals, preferably C 1 -C 6 -alkyl radicals, for example methyl, ethyl, n-butyl, isobutyl, pentyl, hexyl, octyl, nonyl, decyl , Dodecyl, tridecyl or octadecyl radicals.
  • General processes for the preparation of the novel graft copolymers are known per se.
  • the preparation is carried out by free-radically initiated polymerization, preferably in solution, in nonaqueous, organic solvents or in mixed nonaqueous / aqueous solvents.
  • Suitable preparation processes are described, for example, in WO 2007/051743 and WO 2009/013202, to the disclosure of which reference is expressly made with regard to the preparation process.
  • the melt thus obtained can then be cooled and granulated.
  • a so-called hot break or cooling takes place under air or inert gas, for example, on a Teflon or chain belt and subsequent granulation of the cooled melt strand.
  • air or inert gas for example, on a Teflon or chain belt and subsequent granulation of the cooled melt strand.

  • Suitable twin-screw extruders may have a screw diameter of 16 to 70 mm and a length of 25 to 40 D. ,
  • the resulting extrudate strands can be processed into granules with a granulator and these can in turn be further comminuted (ground) into a powder.
  • the granules or powder can be filled into capsules or pressed into tablets using conventional tableting excipients. In this case, further release-controlling adjuvants can also be used.
  • water-soluble high glass transition temperature polymers such as e.g. Polyvinyl pyrroli- don with K values of 17 to 120, hydroxyalkyl or hydroxalkyl used. Too high a glass transition temperature of the formulation can be lowered by adding plasticizers.
