Abstract

The invention discloses a tablet containing clopidogrel hydrogen sulfate. The tablet comprises clopidogrel hydrogen sulfate micropills which are prepared into tablets through coating; the micropills are prepared by clopidogrel hydrogen sulfate, a diluent and an adhesion agent; the diluent is mannitol or / and microcrystalline cellulose; the adhesion agent is an anhydrous ethanol solution of hydroxypropylcellulose or povidone; and an lubricating agent is one or more of magnesium stearate, zinc stearate, talc, polyethylene glycol 6000, stearic acid, sodium stearyl fumarate, sodium lauryl sulfate and hydrogenated vegetable oil.

Description

technical field [0001] The invention relates to an oral solid preparation containing anti-platelet aggregation drugs, in particular to a tablet containing clopidogrel bisulfate and a preparation method thereof. Background technique [0002] Cardiovascular and cerebrovascular thrombotic disease is a common disease in my country and an important cause of death in China. The average incidence of myocardial infarction in my country is about 42 per 100,000 people; and with the improvement of nutritional status, the incidence is increasing. my country is also an area with a high incidence of cerebral thrombosis patients. At present, the number of patients has exceeded 8 million. There are about 1.5 million new cases each year, and more than 1 million deaths each year. Among the survivors, about 25% of them lose their labor force to varying degrees. Among them, severe disability is as high as 40%. Currently, clopidogrel and aspirin are the mainstream drugs for antithrombotic thera...
