POLYMER AND DOSAGE FORM WITH SUSTAINED RELEASE PROPERTIES AND RESISTANCE AGAINST THE INFLUENCE OF ETHANOL

A polymer is polymerized from a monomer mixture containing (a) 70 to 95% by weight of 2-ethylhexyl methacrylate (EHMA) and ethyl methacrylate (EMA) or 2-ethylhexyl methacrylate (EHMA) and methyl methacrylate (MMA), (b) 2.5 to 25% by weight of one or more C2 to C6 hydroxy-alkyl esters of acrylic acid...

Beschreibung
Zusammenfassung:	A polymer is polymerized from a monomer mixture containing (a) 70 to 95% by weight of 2-ethylhexyl methacrylate (EHMA) and ethyl methacrylate (EMA) or 2-ethylhexyl methacrylate (EHMA) and methyl methacrylate (MMA), (b) 2.5 to 25% by weight of one or more C2 to C6 hydroxy-alkyl esters of acrylic acid or methacrylic acid, (c) 2.5 to 15% by weight of one or more C2 to C8 alkyl esters of acrylic acid or of methacrylic acid with a quaternary cationic group in the alkyl group. The polymer is useful for preparing a dosage form with a sustained release profile and resistance against the influence of ethanol.
