Objective: A simple, rapid, precise and accurate RP-HPLC stability indicating method was developed and validated for estimation of Febuxostat in bulk drug and marketed tablet formulation. Methods: The chromatographic separation was achieved on Agilent C18 (250 x 4.6mm, 5 µm) using solvent 15 mM ammonium acetate buffer (pH 4.8) and acetonitrile (30:70 v/v) as a mobile phase at flow rate of 1 mL/min and at ambient column temperature analysis were carried out at detection wavelength 315nm. Result: The method was validated for linearity, precision, accuracy, specificity, LOD and LOQ, and robustness. The linearity was studied in the concentration range of 5-25 µg/mL and correlation coefficient was found to be 0.999. The limit of detection and limit of quantitation were found to be 0.37 µg/mL and 1.13 µg/mL. Febuxostat was subjected to stress condition of degradation including acidic, alkaline, oxidation, photolytic and thermal degradation. Febuxostat is more sensitive toward acidic condition than oxidation and less sensitive towards alkaline, thermal and photolytic degradation. Conclusion: The method is simple, reliable, sensitive and precise which could separate the drug and their degraded product formed under various stress conditions, thus it can be employed as stability indicating method for the determination of FBX in bulk and pharmaceutical dosage form.

A stability indicating method for Indapamide in an oral antihypertensive tablet and bulk dosage forms was developed and validated by reverse phase HPLC (RP-HPLC). The proposed RP-HPLC Shisheido Capcell Pak C18 column was used and column dimension was 250mm × 4.6mm i.d., 5μm partical size at ambient temperature. The mobile phase Methanol and Phosphate Buffer pH 5.8 (60:40) was run in isocratic mode at a flow rate of 1.0ml/minute. The wavelength of Indapamide was selected at 241nm. Indapamide was found as single peak in the chromatogram at 6.58 min. The different chromatographic conditions were applied to determine the drug in pharmaceutical dosage form. The linearity of the proposed method was found in a range of 0.2-1.2μg/ml with coefficient of correlation (r2) value 0.999, slope 8360 and intercept -77.78. The percent RSD of intraday precision and interday precision were found in range of 0.498 - 1.661 and 0.882 - 1.623 respectively. The average accuracy of the method at three different levels of 50, 100 and 150 % were found to be 100.67, 99.50 and 100.65, respectively. The LOQ and LOD expressed as signal to noise ratio (S/N) were found to be 0.03 and 0.08μg/mL with good accuracy and precision. Indapamide was exposed to different stress conditions like alkaline, acidic, thermal, oxidative and photolytic. The stressed samples were analyzed by the proposed method. The proposed methods can be used for routine analysis stability testing and assay of Indapamide in quality control laboratories.

A stability-indicating LC assay method was developed for the quantitative determination of fenofibrate (FFB) in pharmaceutical dosage form in the presence of its degradation products and kinetic determinations were evaluated in acidic, alkaline and peroxide degradation conditions. Chromatographic separation was achieved by use of Zorbax C18 column (250 × 4.0 mm, 5 μm). The mobile phase was established by mixing phosphate buffer (pH adjusted 3 with phosphoric acid) and acetonitrile (30:70 v/v). FFB degraded in acidic, alkaline and hydrogen peroxide conditions, while it was more stable in thermal and photolytic conditions. The described method was linear over a range of 1.0-500 μg/ml for determination of FFB (r= 0.9999). The precision was demonstrated by relative standard deviation (RSD) of intra-day (RSD= 0.56– 0.91) and inter-day studies (RSD= 1.47). The mean recovery was found to be 100.01%. The acid and alkaline degradations of FFB in 1M HCl and 1M NaOH solutions showed an apparent zero-order kinetics with rate constants 0.0736 and 0.0698  min−1 respectively and the peroxide degradation with 5% H2O2 demonstrated an apparent first-order kinetics with rate constant k = 0.0202 per min. The t1/2, t90   values are also determined for all the kinetic studies. The developed method was found to be simple, specific, robust, linear, precise, and accurate for the determination of FFB in pharmaceutical formulations.
