Development And Validation

The prime aim of the present investigation was to develop and validate a novel, precise, accurate, specific, rapid and economical stability- indicating isocratic reverse phase liquid chromatography method for the quantitative simultaneous estimation of valsartan and hydrochlorothiazide in bulk and marketed formulations. Estimation of drugs in this combination was achieved with a C18 column [Kromasil 100-5 C18 column, P134 250 × 4.6 mm] kept at ambient temperature, isocratic mode using mobile phase of composition acetonitrile and phosphate buffer (40:60 V/V, pH 4). The flow rate was 0.8 ml/min and the effluents were monitored at 235 nm, using variable wavelength UV detector. The retention time of valsartan and hydrochlorothiazide were 2.65 min and 3.97 min, respectively. Validation of the method was done according to the ICH guidelines for different analytical parameters. The method was found to be linear over a range of 50-250 μg/mL for valsartan and hydrochlorothiazide. The established method was as reproducible with a %RSD value of less than 2 and having robustness and accuracy within the specified limits. Assay of marketed formulation was determined and was 99.04% and 99.8% respectively. The stressed samples were analyzed. The proposed method was found to be specific and stability indicating as no interfering peaks of degradation compounds and excipients were noticed. The proposed method can be successfully employed in the estimation of commercial formulations.

The separation was carried out using a mobile phase consisting ACN: Buffer (pH 3.5) in the ratio of 55:45 v/v. The column used was Phenomenex luna ODS C18 (250mm X 4.6 mm i.d., 5 μm particle size) with flow rate of 1 ml / min using UV detection at 268 nm. The described method was linear over a concentration range of 2-12 μg/ml for both of Gatifloxacin and flurbiprofen sodium. The retention times of Gatifloxacin and flurbiprofen sodium were found to be 3.710 min. and 6.797 min respectively. Method was validated statistically and recovery studies were carried out. The proposed method has been applied successfully to the analysis of cited drugs either in pure form or in pharmaceutical formulations with good accuracy and precision. The method here in described can be employed for quality control and routine analysis of drugs in pharmaceutical formulations.

Aim: To develop a stability indicating Rp-UPLC method for the simultaneous determination of Lamivudine, Dolutegravir and their degradants in tablets. Methodology: The chromatographic separation was performed on BEH Shield RP18 (2.1 mmX100 mmX1.7 mm) using a isocratic mobile phase Potassium dihydrogen orthophosphate pH 3 adjusted with orthophosphoric acid: methanol (30:70,% v/v) at a flow rate of 0.5ml/min. Column was maintained at room temperature and eluents are monitored at 258 nm. Results: Retention times of the analytes were found to be at 0.81 and 2.78 mins for Lamivudine and Dolutegravir respectively. The calibration of peak area versus concentration, which was linear from 105 to 315 µg/ml for Lamivudine and 17.5 to 52.5 µg/ml for Dolutegravir, had regression coefficient (r2) greater than 0.999. The method had the requisite accuracy, precision and robustness for simultaneous determination of Lamivudine and Dolutegravir in tablets. Conclusion: The proposed method is simple, economical, accurate, precise and can be successfully employed in routine quality control for the simultaneous analysis of Lamivudine and Dolutegravir in pharmaceutical formulations.

A clear chromatographic division was attained on inertsil ODS (4.6 x 250 mm, 5 mm) column, and a mixture of 0.1% trifluoroacetic acid and methanol in the ratio of 40:60 v/v was used as mobile phase. The rate of flow was set at 1 mL/min, and UV detection was achieved at λmax of 255 nm. Injection volume was set to 20 μL. The correlation coefficient of 0.999 was established, and the accurateness was found to be 100.69 and 100.49 for both the drugs, respectively. Therefore, the developed method was simple, specific, precise, and stable. Hence, the method can be employed to estimate the said drugs in other pharmaceutical formulations.
