An accurate, precise, sensitive and reproducible High-performance liquid chromatographic and UV spectrophotometric method were developed and validated for the quantitative determination of ticagrelor, a novel antiplatelet agent used in acute coronary syndrome in bulk drug and pharmaceutical formulation. Chromatography was carried out by isocratic technique on a reversed-phase Thermo C18 (250 Ã— 4.6 mm, 5Î¼m) column with mobile phase consisting of 20 mM KH2PO4: acetonitrile (pH 3.0 with OPA) in the ratio of 20:80 v/v at flow rate of 1.0 ml/min. The retention time for ticagrelor was 8.102Â± 0.3 min. The UV spectrophotometric determinations were performed at 282 nm using water as a solvent. The proposed methods were validated according to International Conference on Harmonization ICH Q2 (R1) guidelines. The linearity range for ticagrelor was 5-25 Î¼g/ml for HPLC and UV method. The linearity of the calibration curves for each analyte in the desired concentration range was good (r2 >0.999) by both the HPLC and UV methods. Both the methods were accurate and precise with recoveries in the range of 98 and 99 % and relative standard deviation <2 %. The developed methods were successfully applied for determination of ticagrelor in tablets.
