Abstract

The invention relates to a medicine composition containing colesevelam hydrochloride and a preparation method thereof. A prescription of the composition comprises a main medicine of colesevelam hydrochloride and two necessary auxiliaries of silicified microcrystalline cellulose and lubricant; the preparation method avoids the complex technique in the wet granulation or the dry granulation, and overcomes the defects of weak tablet fluidity, weak content uniformity, overgreat tablet weight and low compliance of patients of the large-dosage main medicine; the medicine composition can be prepared through the preparation technology of direct powder compression. The colesevelam hydrochloride tablet prescription of the invention has the advantages of rationality, simple and stable preparation technique, better effect on the selection of the auxiliaries and the ratio selection of the main material and the auxiliaries, lower production cost and convenience in industrial application.
