A new method for the simultaneous determination of paracetamol (PR) and lornoxicam (LR) has been developed by reversed phase HPLC from the combination drug product. The separation achieved on C18 column using acetonitrile and 0.02 M potassium dihydrogen phosphate was in the ratio of 35:65 (v/v) as mobile phase at a flow rate of 1.0 mL/min. Both the components were monitored at a single wavelength at 260 nm and the column temperature was maintained at 30?C throughout the analysis. A linear response was found in the concentration range of 125-375 ?g/mL for PR and 2-6 ?g/mL for LR, with the correlation coefficient of more than 0.999. Although the tablet contained a high dose of PR (500 mg) and a low dose of LR (8 mg), the single HPLC method was developed and the intra as well as inter day precision was obtained at less than 2% of RSD. The accuracy results obtained were between 98% and 102%. The drug was intentionally degraded under acidic, basic, peroxide, thermal, and photolytic conditions. The major degradation observed for both PR and LR under peroxide condition indicated that the drug product is susceptible to oxidation. The degraded peaks were properly resolved from PR and LR. Hence, the method is stability indicating.

A simple isocratic reversed-phase HPLC method for quantification of clobetasone in bulk and cream dosage forms has been developed. Chromatographic analysis was accomplished on an C18 column utilizing a mixture of methanol and water (84:16 v:v, pH = 6.0) as mobile phase. An effluent flow rate of 1 mL/min was adjusted and the detection was made at 240 nm wavelength. The method was evaluated according to ICH guidelines Q2 R1 for linearity, specificity, sensitivity, precision and accuracy. The method exhibited good linearity with correlation coefficient (r2) of 0.9993 over the concentration range from 5 to 50 μg/mL. The recoveries of the test drug from the cream sample was found to be 98.56 to 99.51% and the limit of detection and quantification were calculated as 0.85 and 2.83 μg/mL, respectively, suggesting the accuracy and sensitivity of the developed method. The precision was demonstrated by a low percentage of relative standard deviation (<1%) from six independent assay analysis performed for the cream formulation. Stability indicating property of the proposed method was demonstrated by performing the analysis of forced degradation samples. The developed method can be used for estimation of the clobetasone butyrate in bulk and pharmaceutical formulations for routine analysis in the quality control laboratories.

The aim of the present work was to develop and validate an accurate, precise, simple, and efficient stability indicating Reversed phase High Performance Liquid Chromatography method for determination of an abrisentan and its process impurities in bulk and pharmaceutical dosage forms. The drug substance was subjected to stress conditions such as hydrolysis (acid and base), oxidation, photolysis and thermal degradation as per International Conference on Harmonization guidelines to study the stability-indicating profile of drug. Significant degradation was observed during acid hydrolysis and peroxide degradation. The chromatographic conditions were optimized using an impurity-spiked solution and samples generated from forced degradation studies. The method was developed using Agilent XDB-C18 (150×4.5mm, 5μ) column and 10mM NH4OAc (pH-5.2 adjusted with acetic acid): ACN as the mobile phase with gradient programme at a flow rate of 1 mL/min. effluents were monitored at 289 nm.

The mean recovery values were found to be 98.52-100.44% for AMD and its impurities. The degradation rate of AMB in acid, base, peroxide (oxidative) thermal and photolytic degradation processes was found in range 7-22%. The developed analytical method has been validated for specificity, linearity, precision, accuracy, and robustness which were within the acceptance limit according to ICH guidelines. The developed method was successfully employed for routine quality control and stability analysis of AMB in pharmaceutical dosage forms.

Objective: Development of a stability-indicating reverse phase liquid chromatographic (RP-HPLC) method for the simultaneous quantification of 11 impurities in the combined dosage forms of lamivudine and tenofovir disoproxil fumarate drug substances.Methods: Efficient chromatographic separation of all analytes was achieved on a Waters X-terra RP18 column (150 x 4.6 mm, 3.5 mm) using mobile phase A (ammonium acetate buffer, pH adjusted to 5.0±0.05 with dilute orthophosphoric acid) and mobile phase B (mixture of methanol and ammonium acetate buffer in the ratio of 20:80) with the flow rate of 1.0 ml/min in gradient elution mode at 260 nm.Results: The method was validated in terms of the limit of detection, limit of quantification, linearity, accuracy, precision and robustness according to the international conference on harmonisation (ICH Q2R1). Regression analysis showed that the correlation coefficient (r2) is greater than 0.997 for individual active drug substances as well as their related substances. The method has proven very accurate (94.6 % to 108.2 % with % RSD not more than 4.9), highly precise (% RSD of the Intra-day and the inter-day study was not more than 8.9) and robust enough to deliver accurate results, when the chromatographic conditions were altered intentionally. Forced degradation studies were conducted in acidic, basic, thermal, photolytic, humid and peroxide stress conditions, where all the degradation peaks were monitored. Highest degradation of lamivudine was observed under oxidative stress condition and tenofovir was more susceptible to degradation under acidic and alkaline conditions.Conclusion: The present method is able to separate all the related compounds with each other and with the main drug substances with the resolution more than 2.0. The test solution was found to be stable in diluent up to 24 h. The mass balance of forced degradation of formulations, close to 99 %, made this method as a stability indicating method.
