    摘要: New pharmaceutical sustained-release compositions, formulated as tablets, are prepared by mixing the active ingredient with excipient already granulated and coated with polymers and/or copolymers or a polymers- and/or copolymers-mixture substantially insoluble in water. Such pharmaceutical preparations enable one to enhance or to decrease very easily and precisely the sustained-release effect by regulating the granulometry of the excipient, the excipient/active ingredient ratio, the hardness, and the percentage of the polymers and/or copolymers or of the polymers- and/or copolymers-mixture.
