titleOfInvention | Use of a partially neutralized, anionic (meth)acrylate copolymer as a coating for the production of a pharmaceutical form releasing active substance at reduced ph values |
abstract | The invention relates to the use of a partially neutralized, anionic (meth)acrylate copolymer comprising radically polymerized units of 25 to 95 percent by weight of C1 to C4 alkyl esters of acrylic or methacrylic acid and 5 to 75 percent by weight of (meth)acrylate monomers with an anionic group, at least 4 percent of which are neutralized by means of a base, for producing a medicament that is provided with an active substance-containing core and is coated with the partially neutralized, anionic (meth)acrylate copolymer. Said medicament releases at least 30 percent of the active substance contained therein in 30 minutes at a pH at which the active substance is sufficiently soluble and stable and at which the corresponding medicament that is coated with the non-neutralized anionic (meth)acrylate polymer releases less than 10 percent of the active substance contained therein. |
