DEVELOPMENT AND VALIDATION OFRP-HPLC METHOD FOR ESTIMATION OF EDOXABAN TOSYLATE IN TABLET DOSAGE FORMS

A rapid, simple and precise reversed phase high performance liquid chromatography (RP-HPLC) method was developed for the estimation of edoxabantosylate in tablets. The quantification was carried out using a Phenomenex C-18 column (250×4.6 mm i.d., 5µm particle size) in isocratic mode with mobile phase comprising of ammonium acetate buffer andacetonitrile in the ratio of 50:50 (V/V) at a flow rate 1 mL/min. The eluent was monitored at 240 nm. The retention time of the drug was 3.486 min. The calibration curve was linear in the concentration range of 5-25 µg/mL and per cent recovery ranged from 98.25-101.6.The developed method was validated as per ICH guidelines and the results obtained were satisfactory.The method can be applied for routine quality control analysis of edoxabantosylate in tablet dosage forms
