Abstract

The invention discloses an immunomodulator slow-release preparation and a preparation method thereof. A lenalidomide slow-release tablet is composed of a slow-release layer and an optional quick-release layer, wherein the slow-release layer contains active ingredients of lenalidomide and a slow-release framework material simultaneously; the quick-release layer does not contain the slow-release framework material. The lenalidomide slow-release tablet disclosed by the invention is capable of slowly and uniformly releasing medicines by virtue of the slow-release framework material, so as to reduce the release speed, delay the time to peak, prolong the action time of lenalidomide, and provide a uniform and constant blood concentration. Moreover, The lenalidomide slow-release tablet disclosed by the invention is simple in prescription and excellent in quality stability; the preparation process is simple to operate, free from special treatment and production equipment, low in production cost, and beneficial to batch-enlarged industrial production for the product; the preparation method is high in yield, the granulation and crushing procedures are simple and practicable to operate, the intermediate material is good in stability, flowability, compressibility and content uniformity, and completely meets the requirements of tabletting, and the surface of the prepared tablet is smooth and beautiful.
