Abstract
The present study is aimed to develop a linear, precise, and accurate RP-HPLC (Reverse Phase High-Performance Liquid Chromatography) method for the determination of dapagliflozin in the formulation. The method was accomplished on a C18 column (250×4.6mm; 5µm), & Samples were eluted using acetonitrile: water (40:60%v/v) delivered at a flow rate of 1.0ml/min with a chromatographic run time of 10 min. The eluents were observed utilizing a UV detector with a wavelength set at 277nm. The method that was developed resulted in the retention of dapagliflozin at 7.029minutes. Dapagliflozin through current method has shown linearity (r2 > 0.999) over the concentration range of 1-16 µg/ml. The percentage recovery was observed to be within the limits of 98-102%, demonstrating the accuracy of the method. Limit of detection (LOD) and limit of quantification (LOQ) were qualified at 0.049µg/ml and 0.1485µg/ml, respectively. A Linear, precise, accurate, simple, and rapid RP-HPLC method has been developed and validated for the evaluation of dapagliflozin in bulk drug and tablet dosage forms (5mg &10mg) according to ICH Q2(R1) rules. Additionally, the proposed method could be of use in quality control tests of dapagliflozin in pharmaceutical industries.
