titleOfInvention | Use of a partially neutralized anionic (meth) acrylate copolymer as a coating for the production of a medicated form with a release of the active substance at reduced pH values |
abstract | Use of a partially neutralized anionic (meth) acrylate copolymer, consisting of units polymerized in the radicals of 40 to 60% by weight of C1 to C4 alkyl esters of acrylic acid or of methacrylic acid and 60 to 40% by weight of monomers of (meth) acrylate with an anionic group, where more than 10 to 50% of the contained anionic groups are neutralized by a base, for the preparation of a medicated form with a core with active ingredient content that is coated with the copolymer of (meth) partially neutralized anionic acrylate that releases at least 30% of the active substance contained in the space of 30 minutes at a pH value in which the active ingredient is sufficiently soluble and stable and in which a corresponding drug form, which is coated with the non-neutralized anionic (meth) acrylate copolymer, would release less than 10% of the active substance in the space of 30 minutes, where the coating in the drug form it can contain up to 30% by weight of other film-forming polymers that do not have or only present in ionic amounts irrelevant amounts. |
