Abstract

The invention provides a medicament composition of aspirin and diosgenin in view of the limitations of antithrombotic medicaments. The composition has antithrombotic activity significantly higher than aspirin, can significantly reduce the therapeutic dose of aspirin, simultaneously has gastric mucosal protective effect, and can be safely used for long term.

Description

technical field [0001] The invention belongs to the technical field of medicine, and specifically relates to a pharmaceutical composition with antithrombotic effect, its preparation, and its application in the prevention and treatment of cardiovascular and cerebrovascular diseases. technical background [0002] Platelet aggregation and thrombus formation are important causes of ischemic heart and brain injury. Platelet activation, adhesion and aggregation are one of the initiating factors of thrombosis in arteries, and play a role in the pathogenesis of atherosclerosis, coronary events (unstable angina, acute myocardial infarction, sudden cardiac ischemic death), stroke, etc. key role. Therefore, antiplatelet and anticoagulant therapy has become a hot spot in the treatment of reducing clinical ischemic events. [0003] Aspirin is the drug of choice for the prevention and treatment of arterial thrombosis. It is used to prevent transient ischemic attack, myocardial infarctio...
