  • Publication number: 20200030317
    Abstract: A tamper-resistant pharmaceutical dosage form comprising a multitude of particles which comprise a pharmacologically active compound, a polyalkylene oxide, and a disintegrant; wherein the pharmacologically active compound is dispersed in a matrix comprising the polyalkylene oxide and the disintegrant; wherein the dosage form provides under in vitro conditions immediate release of the pharmacologically active compound in accordance with Ph. Eur. The tamper-resistant pharmaceutical dosage form is useful in methods of treat diseases or disorders susceptible to the pharmacologically active compound; and in some embodiments discourages abuse in that when reduced to a powder the powdered dosage form exhibits a lower score for drug-liking than the pharmacologically active compound itself as assessed on a visual analog scale.
