RAPID RP-HPLC METHOD DEVELOPMENT AND VALIDATION OF LURASIDONE HYHROCHLORIDE IN BULK AND TABLET FORM

The RP-HPLC were developed and validated for the estimation of lurasidone HCl as per ICH guidelines. A simple, fast, accurate and precise RP-HPLC method was developed by using methanol: water containing 0.01% ortho phosphoric acid in the ratio of 70:30 (V/V). The method was developed in Eclipse C18 column (100 mm × 4.6 mm, 3.5 μm particle size). The method was found to be linear in the range of 2.5- 15µg/mL with a correlation coefficient value of 0.999. The accuracy studies of RP-HPLC method was performed at three different levels, i.e., 50%, 100%, and 150% and recovery was found to be in the range of 100.1-100.6% .The limit of detection (LOD) and limit of quantification (LOQ) were found to be 0.30-0.92. Satisfactory validation was also obtained from recovery (99.8%) studies, intra-day and interday precision and robustness 2%. The proposed method was found to be accurate, precise and rapid for the analysis of lurasidone.
