PROBLEM TO BE SOLVED: To provide a tamper-resistant dosage form comprising an opioid analgesic, to provide a method for producing the same, and to provide a method for use and treatment thereof.SOLUTION: There is provided a controlled release solid oral pharmaceutical dosage form comprising a controlled release matrix formulation in the form of a tablet or multi-particulates as the object. The tablet or individual multi-particulates can be at least flattened without breaking, characterized by a thickness of the tablet or of the individual multi-particulates after flattening which corresponds to about ≤60% of the thickness of the tablet or of the individual multi-particulates before flattening. In the dosage form, the flattened tablet or flattened multi-particulates provide an in vitro dissolution rate, when measured in a USP Apparatus 1 (basket) at 100 rpm in 900 mL simulated gastric fluid without enzymes (SGF) at 37°C, characterized by the percent amount of an active agent released at 0.5 h of the dissolution that deviates no more than about 20% points from the corresponding in vitro dissolution rate of a non-flattened reference tablet or non-flattened reference multi-particulates.
