Abstract

The invention relates to an indobufen pharmaceutical composition and a quality control method thereof. Particularly, the indobufen pharmaceutical composition contains the following components in parts by weight: 200 parts of indobufen, 30-50 parts of saccharide diluents, 15-40 parts of a fiber diluents, 5-15 parts of a disintegrating agent, 3-8 parts of an adhesive, 1-5 parts of a flow aid and 1-5 parts of a lubricant, wherein the saccharide diluents are selected from mannitol, saccharose, lactose, fructose, glucose, sorbitol, hydrates of the saccharides, and a combination of the saccharides and hydrates. The invention further relates to a preparation method, quality control method and pharmaceutical use of the composition. The indobufen pharmaceutical composition can be used for treating arteriosclerotic ischemic cardiovascular diseases, ischemic cerebrovascular disease and peripheral arterial disease, blood lipid dysbolism, venous thrombosis and diabetes mellitus and preventing thrombosis during extracorporeal circulation operation and presents excellent effects as described in description.
