ABSTRACT

To develop precise, accurate and reproducible stability assay method by RP-HPLC for estimation of dapagliflozin in API and Pharmaceutical dosage form. The adequate separation was carried using agilent C18 (4.6millimeter*150,5micromiter), mixture of acetonitrile: di-potassium hydrogen phosphate with pH-6.5 adjusted with OPA (40:60 %v/v) as a mobile phase with the flow rate of 1 milliliter/minute and the effluent was monitored at 222 nanometer using photo diode array detector . The retention time of dapagliflozin API and dapagliflozin tablet were 3.160 minute and 3.067 minute respectively. Linearity for dapagliflozin was found in the range of 50 -150 microgram/milliliter (R2 = 0.99) respectively. The accuracy of the present method was evaluated at 50 %, 100% and 150%. The % recoveries of dapagliflozin API and tablet were found to be in the range of 99.00 – 99.99 % and 98.50 – 99.99 % respectively. Precision studies were carried out and the relative standard deviation values were less than two. The method was found to be robust. The proposed method was found to be specific, accurate, precise and robust can be used for estimation of dapagliflozin in API and Pharmaceutical dosage form.
