1. An abuse-proofed dosage form thermoformed by extrusion without discoloration and having a breaking strength of at least 500 N, which contains a mixture of:
- i) one or more active ingredients with abuse potential (A) selected from the group consisting of opioids,ii) optionally physiologically acceptable auxiliary substances (B),iii) from 30% by weight to 99.9% by weight of at least one polyalkylene oxide (C), having a molecular weight of from about 4,000,000 g/mol up to 15,000,000 g/mol,iv) optionally at least one wax (D), andv) a further material selected from the group consisting of hydroxypropylmethylcellulose, hydroxypropylcellulose and hydroxymethylcellulose,wherein said extrusion takes place in an extruder at a temperature of from at least thesoftening point of the polyalkylene oxide up to a temperature of below 180°
C., andwherein component (C) and/or the optionally present component (D) serve as acontrolled release matrix material in which the active ingredient with abuse potential(A) is embedded and said dosage form not being in multiparticulate form.

Abstract
The invention relates to a dosage form that is thermoshaped without being extruded and that is safeguarded from abuse, comprising at least one synthetic or natural polymer having a breaking strength of at least 500 N in addition to one or more active substances that could be subject to abuse and optionally physiologically acceptable adjuvants. The invention also relates to a corresponding method for producing said dosage form.
