Clopidogrel is a drug that inhibits platelet aggregation, one is imported called Bolivar, and the other is domestic called Tega. The biggest difference between the two drugs is that one is imported and the other is made in China. The imported one may be more expensive, while the domestic one is cheaper, and the doses of the two drugs are slightly different. Clopidogrel is used to prevent thrombosis by inhibiting platelet aggregation, and is used to prevent and treat cardiovascular and other arterial circulatory disorders or strokes caused by high platelet aggregation, such as stroke, myocardial infarction and long-term antiplatelet aggregation therapy after coronary stenting interventions. Clopidogrel is actually a precursor drug that needs to be metabolized in the liver before it can be converted into an active substance, and long-term use of clopidogrel may cause bleeding. Compared to other anti-platelet aggregation drugs, clopidogrel has a faster onset of action and longer expiration time. Many times clopidogrel plus aspirin, or aspirin plus clopidogrel plus a mono-, di-, or tri-antibody is used. Routinely. Clopidogrel plus aspirin can prevent thrombosis after coronary stenting procedures.
