1. A tamper-resistant pharmaceutical dosage form for oral administration, said pharmaceutical dosage form being a capsule comprising:
- (a) one or more prolonged release particles, wherein each of said one or more particles;
(i) comprises a pharmacologically active ingredient selected from the group consisting of stimulants;
(ii) comprises a physiologically acceptable polymer selected from the group consisting of acrylic polymers and polyalkylene oxides, wherein the physiologically acceptable polymer has a weight average molecular weight of at least 200,000 g/mol, wherein the physiologically acceptable polymer is present in a content of at least 30 wt.-% relative to a total weight of the one or more particles, and wherein the pharmacologically active ingredient is embedded in a matrix comprising the physiologically acceptable polymer;
(iii) has a breaking strength of at least 300 N;
(iv) has a weight of at least 100 mg; and
(v) optionally comprises a film-coating; and
(b) one or more additional particles having a weight of less than 2 mg;
wherein the pharmaceutical dosage form has a total weight greater than a combined weight of the particles (a) and (b);
wherein the pharmaceutical dosage form contains no aversive agent and contains no antagonist; and
wherein the pharmaceutical composition can be chewed without significantly deteriorating tamper-resistance and without significantly altering drug release.
