Reversed phase high performance liquid chromatographic method was developed and validated for estimation of Capecitabine in tablet dosage form. A Phenomenex Prodgy C18, 150x4.6 mm i.d, 5 μm partical size, with mobile phase consisting of mixed buffer of 0.005 M potassium dihydrogen orthophosphate and 0.005 M dipotassium hydrogen orthophosphate (pH 6.8) and acetonitrile in the ratio of 70:30 v/v was used. The flow rate was 1.0 ml/min and the effluents were monitored at 240 nm. The retention time was 5.89 min. The detector response was linear in the concentration of 25-300 mcg/ml, with the regression coefficient of 0.9999. Quantification was done by calculating area of the peak and the detection and quantitation limits were 0.125 and 0.375 mcg/ml respectively. The percentage assay of Capecitabine was 99.91%. The method was validated by determining its accuracy, precision and system suitability. The results of the study showed that the proposed RP-HPLC method can be applied for the determination of Capecitabine in quality control samples and formulations without interferences of the excipients present.
