Abstract

The invention provides a febuxostat tablet and a preparation method thereof, and belongs to the technical field of pharmaceutical preparations. The tablet comprises 10-25 parts of febuxostat, 20-60 parts of a filler, 5-15 parts of a disintegrant, 5-10 parts of an adhesive, 1-5 parts of a lubricant, 1-3 parts of a glidant and 0.1-1 part of a synergist. In the implementation process, the specific parts of the filler and the adhesive are controlled, and the mass ratio of various components is controlled, so that the dissolution rate of the tablet is obviously improved. In the implementation process of the invention, the invention unexpectedly finds that when the mass ratio of the lubricant to the glidant is controlled to be (0.5-5):1, the smoothness of the tablet can be effectively improved,so that the obtained tablet has higher hardness and brittleness. The synergist is also added into the components disclosed by the invention, so that the stability of the tablet is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a febuxostat tablet and a preparation method thereof. Background technique [0002] Febuxostat, whose chemical name is 2-[(3-cyano-4-isobutoxy)phenyl]-4-methyl-5-thiazolecarboxylic acid, is a xanthine oxidase (XO) inhibitor , for the long-term treatment of hyperuricemia with gout symptoms. [0003] Its structural formula is as follows: [0004] [0005] Gout is a crystal-associated arthropathy caused by deposition of monosodium urate (MSU), which is directly related to hyperuricemia caused by purine metabolic disorders and / or decreased uric acid excretion, and belongs to the category of metabolic rheumatic diseases. Gout can be complicated by kidney disease. In severe cases, joint damage and renal function damage can occur. It is often accompanied by hyperlipidemia, hypertension, diabetes, arteriosclerosis and coronary heart disease. [0006]...
