Abstract
Rivaroxaban is an anticoagulant medication that targets a key stage in the blood clotting process, preventing the formation and growth of clots. It is commonly used to prevent thrombosis or inhibit the enlargement of existing clots. Rivaroxaban functions as a Factor Xa inhibitor and is indicated for: reducing the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation, treating deep vein thrombosis (DVT) and pulmonary embolism (PE), as well as reducing the risk of recurrent DVT and PE, and prophylaxis of DVT, which may lead to PE in patients undergoing knee or hip replacement surgery.
A robust, precise, and selective reversed-phase high-performance liquid chromatography (HPLC) method was developed and validated for analyzing Rivaroxaban in raw materials. Isocratic elution at a flow rate of 1 mL/min was performed using a Thermo ODS Hypersil C18 column (4.6 × 250 mm, 5 μm) at ambient temperature. The mobile phase consisted of monobasic potassium phosphate at pH 2.9 and acetonitrile in a 70:30 (v/v) ratio, with UV detection at 249 nm. Linearity was established in the concentration range of 50–1000 ppm (r2 = 0.999), and the retention time for Rivaroxaban was approximately 12 min. The percentage relative standard deviation (RSD) for precision and accuracy was consistently below 2.0 %. Rivaroxaban was subjected to forced degradation under various conditions, including acid and base hydrolysis, hydrogen peroxide oxidation, heat, and UV light exposure. The developed method was validated for specificity, robustness, linearity, accuracy, precision, limit of detection (LOD), and limit of quantitation (LOQ), following International Conference on Harmonisation (ICH) guidelines. The LOD for impurities and degradants was found to be 0.3 ppm, with an LOQ of 1 ppm.
期刊介绍：
The Journal of Chromatography B publishes papers on developments in separation science relevant to biology and biomedical research including both fundamental advances and applications. Analytical techniques which may be considered include the various facets of chromatography, electrophoresis and related methods, affinity and immunoaffinity-based methodologies, hyphenated and other multi-dimensional techniques, and microanalytical approaches. The journal also considers articles reporting developments in sample preparation, detection techniques including mass spectrometry, and data handling and analysis.
Developments related to preparative separations for the isolation and purification of components of biological systems may be published, including chromatographic and electrophoretic methods, affinity separations, field flow fractionation and other preparative approaches.
Applications to the analysis of biological systems and samples will be considered when the analytical science contains a significant element of novelty, e.g. a new approach to the separation of a compound, novel combination of analytical techniques, or significantly improved analytical performance.
