Abstract

The invention relates to a tablet containing clopidogrel sulfate and aspirin active compositions and a preparation method thereof, and belongs to the technical field of medicines. The prescription is mainly composed of the active compositions clopidogrel sulfate and aspirin and other auxiliary materials. The usage amount of raw materials and auxiliary materials in per 1000 clopidogrel-sulfate aspirin tablets: 98 g of clopidogrel sulfate, 50.0 g-100.0 g of aspirin, 110.2 g-130.0 g of mannitol 200SD, 30.0 g-60.0 g of corn starch, 60.0 g-80.0 g of microcrystalline cellulose, 3.0 g-6.0 g of polyethylene glycol 6000, 2.0 g-4.0 g of hydrogenated castor oil, 3.0 g-6.0 g of stearic acid, 8.0 g-12.0 g of micropowder silica gel, and 15.0 g-20.0 g of low-substituted hydroxy propyl cellulose. The preparation technology of the prescription comprises weighing all raw materials and all internally-added compositions, mixing uniformly and granulating by using a dry process, adding all externally-added compositions after the dry-process granulating yield is calculated out, then utilizing a double-layer tablet press for tablet pressing, and finally employing an alcohol water solvent (alcohol/water=80/20) to prepare a dressing liquid for dressing. Compared with common single prescriptions clopidogrel sulfate tablet and aspirin tablet, the disclosed tablet containing clopidogrel sulfate and aspirin active compositions helps to reduce drug administration frequency of a patient, improve adaptability of a patient, and has synergic effect and relatively good curative effect by simultaneously using the two active compositions.

Description

technical field [0001] The invention relates to a tablet containing active ingredients of clopidogrel hydrogen sulfate and aspirin and its preparation process. In particular, the prescription uses mannitol 200SD as a filler, which can well solve the sticking and dissolution problems of the tablet during the production process. At the same time, the two active ingredients are all granulated by dry method, and the plain tablets are coated with a coating solution prepared by alcohol and water solvent, which can minimize the increase of related substances and greatly improve the safety of the drug while ensuring the curative effect. field of medical technology. Background technique [0002] According to the latest data of the U.S. pharmaceutical industry, clopidogrel (Plavix, trade name Plavix) is now the top-selling drug in the U.S. pharmaceutical market. Previously the United States Pfizer The pharmaceutical company's Lipitor drug reclusive throne, but since the patent prote...
