Embodiment 1

[0032] Example 1 Validation of the method for the determination of isomers Edox-II and Edox-III in edoxaban tosylate hydrate according to the present invention.

[0033] Chromatographic column: DAICEL CHIRALCEL OX-H chiral chromatographic column (size 4.6mm×250mm, 5μm);

[0034] Mobile phase: methanol-ethanol-diethylamine (40:60:0.3);

[0035] Detection wavelength: 290nm;

[0036] Flow rate: 1.0mL / min;

[0037] Column temperature: 35°C.

[0038] 1.1 System suitability test

[0039] Take an appropriate amount of Edox reference substance, Edox-II and Edox-III, add mobile phase to dissolve and make a mixed solution containing 1 mg of Edox, 5 μg of Edox-II and 5 μg of Edox-III per 1 ml, accurately measure 20 μl, and follow the above chromatographic conditions Injection analysis, the result shows: Edox-Ⅲ, Edox, Edox-Ⅱ peaks successively, and the resolution between the three is 15.5 and 13.3, reaching the baseline separation (see figure 1 ).

Embodiment 2

[0063] Example 2 Determination of isomers Edox-II and Edox-III in the Edoxaban Toluenesulfonate Hydrate Tablets of the present invention.

[0064] Take an appropriate amount of Edox reference substance, Edox-II and Edox-III, add mobile phase to dissolve and make a mixed solution containing 1 mg of Edox, 5 μg of Edox-II and Edox-III per 1 ml, as a system suitability solution. Take an appropriate amount of edoxaban tosylate hydrate tablet fine powder, accurately weighed, add mobile phase to dissolve and dilute to make a solution containing about 1.0 mg of edoxaban tosylate hydrate per 1 ml, shake well, filter Then, as the test solution, accurately measure 1.0ml, put it in a 100ml measuring bottle, dilute to the mark with mobile phase, shake well, and use it as a control solution. Take an appropriate amount of blank excipients for Edoxaban Toluenesulfonate Hydrate Tablets, add mobile phase to dissolve and dilute to make a solution of corresponding concentration, as the blank exci...

Abstract

The invention discloses a method for separating and measuring edoxaban tosylate hydrate and its isomer impurities by chiral high-performance liquid chromatography. The silica gel of methyl phenyl carbamate) is the chiral chromatographic column of filler, and mobile phase is the mixed solution of the methanol-ethanol that adds basic additive. By adopting the method of the present invention, complete separation of Edoxaban from the isomers Edox-II and Edox-III can be realized. The method is convenient to operate, has been verified by the method, has good method specificity, high sensitivity, and precision and accuracy. The method can accurately carry out the quantitative analysis of the isomers Edox-II and Edox-III of the edoxaban toluenesulfonate hydrate raw material drug and its preparations, thereby ensuring that the edoxaban toluenesulfonate hydrate and its preparations quality controllability.

Description

technical field [0001] The invention belongs to the field of drug analysis, in particular to a method for separating and measuring edoxaban tosylate hydrate and its isomer impurities by chiral high-performance liquid chromatography. Background technique [0002] Edoxaban Toluenesulfonate Hydrate is a small molecule oral anticoagulant developed by Japan's Daiichi Sankyo Co., Ltd., which is a coagulation factor X (FXa) blocker. It was approved by the Japanese Ministry of Health, Labor and Welfare (MHLW) in April 2011. Approved for marketing in Japan, it is used to prevent venous thromboembolism after major orthopedic surgery, including total knee surgery, total hip surgery and hip fracture surgery. It was approved by the US Food and Drug Administration (FDA) in January 2015 as a commodity Savaysa is listed in the United States for reducing the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation. [0003] The structure of edoxaban tosylate hy...
