titleOfInvention | The use of polymer mixtures for the production of coated pharmaceutical formulations and pharmaceutical formulation with mixed polymeric coating |
abstract | The invention relates to the use of mixture of 2 to 60 wt. % of one or more polymers (I) with 40 to 98 wt. % of one or more polymers (II), whereby the polymer (I) is a (meth)acrylate copolymer, containing 90 to 100 wt. % radically polymerised of 40 to 95 wt.% of C1 to C4 alkyl esters of acrylic or methacrylic acid and 5 to 60 wt. % of units of (meth)acrylate monomers with an anionic group with 0 to 10 wt. % of further vinylic polymerisable monomers and polymer(II) is a vinyl polymer different from polymer (I) or a polysaccharide or a derivative of a polysaccharide, containing 88 to 100 % neutral monomer units and up to 12 wt. % polymerisable monomer units with ionic groups, for production of a coated pharmaceutical formulation, containing an active agent core and a polymeric coating made from the mixture of polymers (I) and (II), characterised in that the glass temperature of polymer (I) is not more than 70 ~C and an active agent release profile is achieved, whereby the agent release is delayed with relation to a pharmaceutical formulation with a coating made exclusively of polymer (I), starting with the same pH. The invention further relates to a pharmaceutical formulation with a selected polymer (I). |
