New Stability Indicating HPLC Method for Related Substances in Dapagliflozin

Abstract

The requirements established by the International Council for Harmonization (ICH) for the measurement of dapagliflozin from tablets were satisfied by the development and successful implementation of an reversed-phase high performance liquid chromatography (RP-HPLC) technique that is characterized by its speed, precision, and accuracy. In order to separate the samples, an isocratic mode was used on a Princeton C18 column that was operating at a flow rate of 1-mL per minute. The phase was composed of acetonitrile and 0.1% triethylamine in a volume-to-volume ratio of 50:50, with a pH of 5.0 and a detection wavelength of 224 nm. 5.163 minutes was the retention time that was determined to be best under the circumstances of the chromatographic analysis. Based on the correlation value of 0.999, it can be concluded that the procedure adhered to Beer-Lambert’s law within the measurement range of 10 to 70 μg/mL. The findings not only verified the claim that was made on the label, but they also validated the mean percent drug concentration that was specified for the commercial tablet formulation, which was 100.57%. Following the completion of an investigation, it was discovered that the approaches that were proposed have sufficient proportions of precision measurements, robustness, accuracy, range, and linearity. As part of the technique for stress testing, a number of criteria were evaluated and evaluated overall. The elements that were considered to be among these were light, humidity, temperature, oxidation, and pH (acid/base).
