1. A tamper-resistant tablet comprising(i) a matrix material in an amount of at least 40 wt. % of a total weight of the tablet;
- and(ii) a plurality of particulates in an amount of not more than 60 wt. % of the total weight of the tablet;
wherein said particulates comprise (a) a pharmacologically active compound selected from the group consisting of hydrocodone, hydromorphone, oxycodone, oxymorphone, morphine, tapentadol, tramadol, and the phyiologically acceptable salts thereof and (b) a polyalkylene oxide having a weight average molecular weight of at least 200,000 g/mol;
the polyalkylene oxide being present in the particulates in an amount of at least 25 wt. % based on a total weight of the particulates;
wherein said particulates do not comprise a disintegrant;
wherein said particulates form a discontinuous phase within the matrix material;
wherein said particulates have a breaking strength of at least 300 N; and
wherein the tablet releases after 30 minutes at least 90% of the pharmacologically active compound when measured in vitro with a paddle apparatus equipped without a sinker, at 50 rpm, at 37±
5°
C., in 900 ml simulated intestinal fluid at pH 6.8.
