    摘要: 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.

    摘要: An X-ray contrast composition comprising particles consisting essentially of a non-radioactive crystalline organic x-ray contrast agent having a surface modifier adsorbed on the surface thereof in an amount sufficient to maintain an effective average particle size of less than 400 nm, and a pharmaceutically acceptable carrier therefor is useful in x-ray diagnostic medical imaging methods. The agents can be delivered to a specific tissue or fluid site, for example, the blood pool, liver or spleen. In one embodiment involving intravenous administration, preferred compositions provide effective imaging of the blood pool for remarkably long times.
