| titleOfInvention | Use of partially neutralized anionic (meth) acrylate copolymers as coatings for the manufacture of pharmaceuticals which release active ingredients at reduced pH values |
| abstract | The present invention provides for the preparation of a medicament having an active ingredient-containing core coated with a partially neutralized anionic (meth) acrylate copolymer, 25 to 95 weight of C 1 -to C 4 -alkyl esters of acrylic acid or methacrylic acid. Partially neutralized anionic (meth) acrylate air, consisting of 5 to 75% by weight of free radical polymerized units of (meth) acrylate monomer with anionic groups and at least 4% of the contained anionic groups neutralized by base It relates to the use of coalescing. The agent is coated with an unneutralized anionic (meth) acrylate copolymer to release less than 10% of the active ingredient contained within 30 minutes and at a pH at which the active ingredient is adequately soluble and stable, At least 30% is released within 30 minutes. |
