Abstract

The invention relates to a method for detecting an antiplatelet drug in blood plasma by using an ultra-high performance liquid chromatography-tandem mass spectrometry technology. The method has the advantages that the pretreatment process is simple, the cost is low, the sensitivity is high, the specificity is high, separation and detection of the antiplatelet drug are completed within 5 min, the accuracy degree and precision basically meet the requirements, the method can be used for quantitative analysis of the clinical antiplatelet drug, and a reliable detection method is provided for monitoring the treatment concentration of the clinical antiplatelet drug.

Description

technical field [0001] The invention belongs to the technical field of blood plasma detection, and in particular relates to a method for detecting antiplatelet drugs in blood plasma by ultra-high performance liquid chromatography tandem mass spectrometry. Deshydroxyethoxy Ticagrelor (DHTIC), aspirin (Acetylsalicylic acid, ASA), salicylic acid (Salicylic acid, SA), clopidogrel (Clopidogrel, CLOP) and clopidogrel carboxylic acid metabolite (Clopidogrel Carboxylic Acid, CLOPC) . Background technique [0002] Aspirin is a commonly used non-steroidal drug, which was originally used for antipyretic and analgesic. Later studies found that the use of small doses of aspirin can inhibit the aggregation of platelets, reduce the adhesion rate of platelets, and prevent the formation of thrombus. Oral aspirin 75mg is used as a preventive drug, and is widely used in the prevention of ischemic cardiovascular disease, and can be used in patients with myocardial infarction when used in low d...
