Medicine composition of trifusal and clopidogrel

Abstract

The medicine composition has synergistic active components trifusal and clopidogrel, and its clopidogrel exists in free state or pharmaceutically acceptable salt. The medicine composition is used in treating stable or unstable angina pectoris and other cardiac and cerebral vascular diseases. Pharmaceutical experiments prove the synergistic effect of trifusal and clopidogrel in the medicine composition and the medicine composition has blood platelet inhibiting rate superior to that of aspirin-clopidogrel composition and high safety suitable for long -term taking.

Description

Technical field: [0001] The present invention relates to a novel combination with anti-platelet aggregation activity consisting of triflusalox and clopidogrel, and a pharmaceutical composition containing the two active ingredients. Background technique: [0002] Vascular disease is a systemic disease. The clinical manifestations are different due to the different sites of thrombosis. A vascular event occurs in one vessel, which means that the risk of vascular events in other vessels increases. According to statistics, the death caused by atherosclerotic thrombosis accounts for 28.7% of the total death of the population, mainly due to coronary artery events and cerebral artery events, followed by other peripheral arterial diseases, and two or even three vascular lesions may coexist . The pathological basis of vascular events is atherosclerosis, and the first step in pathophysiology is platelet activation. Therefore, antiplatelet therapy is crucial for the prevention of vascu...

Problems solved by technology

[0006] However, the use of aspirin is also limited clinically. For example, many patients are allergic to aspirin; the risk of upper gastrointestinal bleeding is doubled when aspirin is used in the antithrombotic dose range of 75-100mg / d. Other means such as enteric coating and taking with food cannot solve the problem
