摘要

A controlled release, drug-delivery tableted composition comprising, by weight, an uncrosslinked or crosslinked polymer of (a) about 5-40% of a vinyl amide, (b) about 10-70% of (meth)acrylic acid, (c) about 5-40% of a long chain alkyl (meth)acrylate or acrylamide, and (d) about 0-60% of a lower alkyl (meth)acrylate, and a pharmaceutical medicament.
