Abstract :
A simple, specific, precise and accurate Reverse Phase High Performance Liquid Chromatography (RP-HPLC) method was developed and validated for the quantitative estimation of Torsemide in Bulk and Pharmaceutical dosage form. The proposed RP-HPLC method was carried out on Zorbax C18 (250x4.6mm), 5?m column with mobile phase phosphate buffer and methanol (50:50) (v/v). The pH of phosphate buffer was adjusted by Ortho- phosphoric acid to 3.5. The flow rate was 1.3 mL/min and the detection wavelength was 288nm. The retention time of torsemide was found at 6.0±0.2min. The method was validated for specificity, precision, accuracy, linearity and robustness. The linearity range was 10-30 ?g/mL and correlation coefficient (r2) was found to be 0.9980. The mean % recovery for Torsemide was found to be 99.80. The developed method could be employed for the routine analysis of Torsemide from different formulations and for the Torsemide calculations as well.
