Abstract

The invention relates to a novel oral enteric preparation which is composed of 0.1-1000mg of Grel drugs, or medically acceptable salts, ester or derivatives, 37.5-325mg of aspirin and at least one medically acceptable load, wherein the Grel drugs, or medically acceptable salts, esters or derivatives are clopidogrel, prasugrel, brilinta, sarpogrelate, ozagrel, anagrelide, pamicogrel, or medically acceptable salts, ester or derivatives, preferably, clopidogrel sulfate. The oral enteric preparation is used for curing acute coronary syndrome (ACS), angor pectoris, stroke, myocardial infarction or cardia cerebrovascular diseases of patients. According to the oral enteric preparation, adverse reactions such as functional gastrointestinal disorders, nausea, vomit, gastritis, concealed hemorrhage, ulcer exacerbation and gastrointestinal bleeding caused by strong stimulus of aspirin to stomach can be avoided.

Description

technical field [0001] The present invention relates to a novel oral enteric-coated preparation, which consists of 0.1-1000mg of gray drug or its pharmaceutically acceptable salt or ester or its derivative, 37.5-325mg of aspirin and at least one pharmaceutically acceptable The composition of the carrier is used for preventing, delaying the progress or treating patients with acute coronary syndrome, angina pectoris, stroke, myocardial infarction, ischemic disease or cardiovascular and cerebrovascular diseases, and belongs to the field of medical technology. Background technique [0002] Cardiovascular disease, including coronary heart disease, stroke or peripheral vascular disease, is the main cause of human death. Cardiovascular disease has been the first cause of death in my country since 1990. The 2008 "Statistical Bulletin on China's Health Development" shows that the number of deaths caused by cardiovascular disease has accounted for 40.27% of the total number of deaths ...
