New, simple and economical high pressure liquid chromatography method has been developed for the simultaneous quantification of Pioglitazone and Rosiglitazone.By using Waters HPLC e-2695 quaternary pump with a PDA detector of 2998 instrument the chromatographic separation of Pioglitazone and Rosiglitazone was achieved on the column of Inertsil ODS (150x4.6mm, 3.5 µ) using an isocratic elution with a buffer containing 0.1percentformic acid and acetonitrile at a rate of 30:70 as a mobile phase with a flow rate of 1 ml/min at ambient temperature. A detector wavelength of 261 nm utilizing the PDA detector were given in the instrumental settings. The linearity was studied between the concentration range of 3-45 µg/ml of Pioglitazone and 1-15 µg/ml of Rosiglitazone were injected.The plotted calibration curves were linear with a regression coefficient of R2> 0.999, indicates that the linearity was with in the limit. As a part of method validation the parameters like specificity, linearity, accuracy, ruggedness, robustness were determined and the results were found to be within the allowable limit. The method developed was found to be applicable to routine analysis and to be used for the measurement of both active pharmaceutical ingredients (i.e, Pioglitazone and Rosiglitazone).Validation of the proposed method was carried out according to an International Conference on Harmonization (ICH) guidelines. Since, there is no HPLC method reported in the literature for the estimation of Pioglitazone and Rosiglitazone, there is a need to develop quantitative methods under different conditions to achieve improvement in specificity, selecivity etc.

An RP-HPLC method was developed for the quantification of related impurities of lurasidone and its formulation. The chromatographic separation employs gradient elution using an Inertsil ODS C18 (150x4.6) mm, 5μm columns. Mobile phase consisting of solvent A-buffer (pH 3.0): methanol (90:10 %v/v) and solvent B-acetonitrile: water (80:20 % v/v) delivered at a flow rate of 1.0 mL/min. The analytes were detected and quantified at 210 nm using PDA. The method was validated as per ICH guidelines, demonstrating to be a simple, precise, selective, linear and accurate within the corresponding range of impurities of lurasidone. Linearity was observed in the concentration range of 2-6 µg/mL. The RT for Lurasidone was about 18.5 min and three known impurities at RRT about 0.15, 0.21 and 0.36. The specificity of the method was investigated under different stress conditions including hydrolytic, oxidative, photolytic and thermal as recommended by ICH guidelines. Relevant degradation was found to take place under oxidative conditions. Degradation impurities did not interfere with the RT of drug. The peak purity obtained with the aid of PDA detection and satisfactory resolution between related impurities established the specificity of the determination. All these results provide the stability indicating capability of the method.
