  • Publication number: 20140112980
    Abstract: An abuse-resistant controlled release pharmaceutical composition comprising a pharmaceutically effective amount of discrete particles of an active capable of abuse, wherein surfaces of said particles are wetted with a water insoluble coating material, and preferably wherein said composition comprises a matrix, in which said particles are distributed, and which renders the abuse-capable compound within the matrix difficult to separate from the matrix; and a method for the preparation of a controlled release pharmaceutical composition having a reduced potential for abuse, comprising applying a pressure force to a mixture comprising a water insoluble material, and particles of a pharmaceutically active compound capable of inducing in a subject a reaction that is physiologically or psychologically detrimental if administered in an immediate release dosage form, thereby resulting in surface coated particles, and incorporating said surface coated particles into a pharmaceutical composition
