Development and Validation of Stability Indicating RP-HPLC Method for Canagliflozin

A simple, rapid, accurate and precise RP-HPLC method has been developed and validated for the determination of Canagliflozin using Grace C18 (250mm x 4.6 I.D, Particle size: 5 micron) with mobile phase consisting of Methanol: Water (90: 10% v/v). The flowrate was 0.9mL/min. The detection was carried out at wavelength 290nm. The retention time of canagliflozin were found to be at 4.413min. In calibration curve experiments, Linearity was found to be in concentration range 1–5 μg/mL(R2= 0.998) with regression equation y = 33918x + 85331. Canagliflozin was subjected to stress condition including acidic, alkaline, oxidation and photolytic. The method was validated for linearity, precision, accuracy and robustness. The proposed method was successfully used for estimation of Canagliflozin in bulk and tablet dosage form. Validation studies revealed that method is rapid, reliable and reproducible.
