Aims: To develop and validate a new, simple, rapid, precise, and accurate An Eco-friendly RP-HPLC and UV-Method Development and Validation for an estimation of Tolvaptan in Bulk and Tablet dosage form followed by Forced Degradation Studies Place and Duration of the Study: The present work has been carried out at Ali-Allana College of Pharmacy, Akkalkuwa between November-2020 to April-2021. Methodology: The UV-Spectroscopic method was developed for the estimation of tolvaptan in bulk and tablet dosage form. The solvent selected for the tolvaptan UV analysis was 4% aq. SLS solution, the solution of 10µg/ml was scanned in UV region from 200-400 nm and the λmax value was determined. The RP-HPLC method was developed on Sunsil C18 150 mm x 4.6mm x 5μ column using acetonitrile: water [45:55] as mobile phase at flow rate 1.0 ml/min and UV detection at 266 nm. Results: The maximum absorbance was observed at 266 nm. The wavelength 266 nm was selected for further analysis of tolvaptan. The calibration curve was determined using drug concentrations ranging from 20-100 µgm/ml. The system suitability was performed by injecting a standard solution containing 200µg/ml of tolvaptan in six replicates. For two of them, the peak asymmetric were <1.5 and the theoretical plate number was >2000, and the %RSD of tolvaptan was less than 2. Conclusion: From the above results, it was concluded that the developed UV and RP-HPLC methods are precise and accurate and can be applied for the quantitative estimation of tolvaptan from bulk and tablet dosage forms. The method can be used for routine testing of tolvaptan by the pharmaceutical industry. Validation of the developed method was done as per International Conference on Harmonization (ICH) Q2R1 guidelines.

A simple, rapid, accurate and precise RP-HPLC method was developed and validated for the determination of Istradefylline in table dosage form. Chromatographic analysis of the drug was achieved on Shimadzu HPLC comprising of LC- 20 AD binary gradient pump, a variable wavelength programmable SPD-20A detector and SCL system controller. C18G column (250 mm x 4.6 mm, 5 μ) as stationary phase with mobile phase consisting of 0.1 % orthophosphoric acid and acetonitrile in the ratio of 30: 70 v/v. The method showed a good linear response in the concentration range of 10-90 μg/ml with correlation coefficient of 0.9993. The flow rate was maintained at 1.0 ml/min and detection was carried out at 246 nm. The retention time was 3.125 min. The method was statistically validated for accuracy, precision, linearity, ruggedness, robustness, solution stability, selectivity and sensitivity. The results obtained in the study were within the limits of ICH guidelines and hence this method can be used for the determination of istradefylline in tablet formulation.

A simple, accurate and precise RP-HPLC method was developed for the simultaneous estimation of the linagliptin and empagliflozin in tablet dosage form. Chromatogram was run through Kromasil 250 x 4.6 mM, 5mM column, mobile phase containing 0.1% o-phosphoric acid buffer and acetonitrile in the ratio of 60:40%v/v was pumped through column at a flow rate of 1 mL/min. The optimized wavelength was 230 nm. Retention times of linagliptin and empagliflozin were found to be 2.759 min and 2.139 min. %RSD of the Linagliptin and Empagliflozin were found to be 0.5 and 0.6 respectively. Percentage assay was obtained as 99.91% and 100.15% for linagliptin and empagliflozin, respectively. LOD, LOQ values obtained for linagliptin and empagliflozin were 0.23 μg/ml and 0.44 μg/mL and 0.70 μg/mL and 1.34 μg/mL, respectively. Thus, the current study showed that the developed RP-HPLC method is sensitive and selective for the estimation of linagliptin and empagliflozin in combined dosage form.
