title: [Pharmacologically active polymers. 9th communication: retard forms of morphine antagonists (author's transl)].
abstract: Acryloyl, methacryloyl, N-vinylcarbamoyl, and methacryloyl-glycyl derivatives of the morphine antagonist (--)-alpha-5,9-dimethyl-2-(3-furylmethyl)-2'-hydroxy-6,7-benzomorphane have been synthesized. The different unsaturated derivatives were copolymerized with appropriate comonomers to yield water-soluble polymers. Pharmacological tests in mice showed a 2--30 fold increase in duration of action in comparison to the free antagonist. The binding of the antagonist to the polymers resulted in a reduced acute toxicity.
