Abstract
The invention discloses a detection method of ticagrelor in human plasma and active metabolite concentration thereof. The method comprises the following steps: (1) preparing a standard working solution; (2) treating a sample; (3) manufacturing a standard curve; (4) quantitatively analyzing: treating a test sample according to the method of step (2), and computing according to a standard curve equation obtained in the step (3) to obtain the ticagrelor in the human plasma and the concentration of the active metabolite concentration thereof. The ticagrelor in the human plasma and the concentration of the active metabolite concentration thereof are determined by applying the high-performance liquid chromatography (HPLC), the ticagrelor in the human plasma and the concentration of the active metabolite concentration thereof can be accurately quantified; through the reasonable selection of a chromatographic column, a pre-treatment method, mobile phase and a mass spectrum condition and the optimization of the flow velocity, the mobile phase proportion, the chromatographic condition and like experimental conditions, the series of methodology verifies that the whole quantitative detection method is practicable, simple and convenient for operation, good in repeatability, good in accuracy, and strong in operability, and can be directly applied to the plasma sample detection analysis of the clinical patient and the related pharmacokinetics analysis.
Description
technical field [0001] The invention relates to a method for detecting the concentration of ticagrelor and its active metabolites in human plasma by using high-performance liquid chromatography (HPLC), which can be used for clinical drug concentration monitoring. The invention belongs to the technical field of drug analysis. Background technique [0002] Ticagrelor, also known as Belinda, is a novel, oral, reversible platelet adenosine diphosphate (ADP) P2Y receptor antagonist. At the same time, the active metabolite AR-C124910XX can be rapidly generated after ticagrelor is absorbed. Both ticagrelor itself and its metabolites are active, and the activity of the drug itself is stronger than that of its metabolites. Therefore, it can rapidly Potently inhibits ADP-mediated platelet aggregation. As a platelet inhibitor, ticagrelor is widely used in patients with acute coronary syndrome, including those receiving drug therapy and percutaneous coronary intervention (PCI), to red...
