摘要：

Dosage forms comprising preparations of slightly water-soluble active substances in a polymer matrix of polyether copolymers, the polyether copolymers being obtained by free radical polymerization of a mixture of from 30 to 80% by weight of N-vinyllactam, from 10 to 50% by weight of vinyl acetate and from 10 to 50% by weight of a polyether, and of at least one slightly water-soluble polymer in which the slightly water-soluble active substance is present in amorphous form in the polymer matrix.
