ABSTRACT: An accurate, precise, and simple stability-indicating and RP-HPLC method was developed and validated for the estimation of Remogliflozin Etabonate in bulk and pharmaceutical dosage forms. Primacel C18 (150 × 4.6mm, 5µm) column, with mobile phase Acetonitrile: Water (70:30, v/v) at isocratic mode, was used for the development of this method. At wavelength 280nm, and flow rate of 1ml/min was maintained. The retention time for remogliflozin etabonate was about 2.6 min. This method was validated with respect to ICH guidelines for linearity, the limit of detection, the limit of quantification, precision, accuracy, robustness, solution stability, and forced degradation studies. Linearity was performed in the concentration range of 25µg/ml to 150µg/ml with a correlation coefficient of 0.999. The percentage recovery for Remogliflozin Etabonate was found to be within limits of 98% - 102%. The %RSD was also found to be less than 2% which is within limits. Forced degradation studies result in maximum degradation occurred in alkali, acid, and peroxide degradation studies. There was no degradation occurred in photolytic and thermal degradation studies.

INTRODUCTION: Remogliflozin Etabonate is an anti-diabetic drug, chemically known as 5-Methyl-4-[4-(1-methyl ethoxy) benzyl]-1-(1-methylethyl)-1H-pyrazol-3-yl-6-O-(ethoxycarbonyl)-β-D-glucopyranoside. It inhibits the sodium-glucose transport proteins (SGLT), which are responsible for glucose reabsorption in the kidney. Blocking this transporter causes blood glucose to be eliminated through the urine. The structural formula is as shown in Fig. 1 1-3.
FIG. 1: CHEMICAL STRUCTURE OF REMOGLIFLOZIN ETABONATE
In the literature survey, it was found that there is no published literature for Remogliflozin Etabonate, but we found some articles for dapagliflozin, empagliflozin, and canagliflozin, which belong to the family of Remogliflozin 4-17. In the present work, efforts are made to develop a simple, accurate, and precise RP-HPLC and solution stability method for Remogliflozin Etabonate in bulk and pharmaceutical dosage form and to validate it in accordance with ICH guidelines 18, 19.
MATERIALS AND METHODS: Remogliflozin Etabonate is a gift sample from Metrochem Pvt Ltd, Hyderabad, India. REMO®-ZEN 100mg (Formulation was manufactured by Glenmark Pharma limited). HPLC grade chemicals were preferred for the development of the method; this was obtained for Merck, Hyderabad, India. The method development conditions are described in Table 1.
Selection of Wavelength: Wavelength was fixed at 280nm by performing UV Spectroscopy Fig. 2.

Acetonitrile: Water (70:30, v/v) is used as mobile phase at a flow rate of 1 ml/min Rheodyne injector with 25 µl loop was used for injecting the sample, and the sample was analyzed at 280nm.
Preparation of Mobile Phase: 70ml of HPLC grade Acetonitrile is taken into a mobile phase reservoir, and 30ml of HPLC grade water is added to it, and then it is kept for sonication for 15 mins, sonicated, and degassed.
Preparation of Standard Solution of Remogliflozin Etabonate: 100mg API of Remogliflozin Etabonate is dissolved in 100ml solvent (ACN) and the concentration is 1000µg/ml.
Preparation of Sample Solution: Estimation of Remogliflozin Etabonate (REMO®-ZEN) in dosage form, 20 tablets were weighed individually, and an average weight of the tablets was calculated and triturated into fine powder. 100mg equivalent powder is weighed and transferred it into a 100ml volumetric flask, then dissolve it using 30ml of a suitable solvent (ACN) and sonicated it for 15 min, then make up the volume of the contents in volumetric flask up to the mark using same solvent (ACN) and filter it using Whatman filter paper (No. 1) the concentration obtained is 1000µg/ml. from this solution various sample solutions are prepared and validated according to ICH guidelines.
Preparation of Calibration Curve: From the standard solution pipette out 0.25ml, 0.5ml, 0.75ml, 1ml, 1.25ml & 1.5ml into respective 10ml volumetric flasks and make up the volume up to the mark using suitable solvent (ACN) the concentrations are 25µg/ml, 50µg/ml, 75µg/ml, 100µg/ml, 125µg/ml and 150µg/ml. then the solutions were injected thrice using 25µl injector at the flow rate 1ml/min, at 280nm the chromatograms are recorded and calibration curve was plotted by taking concentration on X-axis and peak area on Y-axis.

CONCLUSION: From the obtained result, it was concluded that a simple, rapid, sensitive, linear, accurate, rugged, robust, and precise method was developed for the estimation of Remogliflozin Etabonate by HPLC. Various validation parameters like Specificity, Linearity, Precision, LOD, LOQ, Accuracy, Solution Stability, and Forced Degradation Studies were carried out. The linearity was obtained in the concentration range of 25µg/ml - 150µg/ml with correlation factor (r2) 0.999. The %RSD for all the parameters was found to within limits i.e., less than 2%, and % recovery was also found to within limits i.e., 98% - 102%. Hence, it was concluded that the projected method can be used for the determination of Remogliflozin Etabonate by Stability indicating and RP-HPLC method.
ACKNOWLEDGEMENT: I would like to thank our Principal, Dr. K. Abbulu, CMR College of Pharmacy, Hyderabad, for providing all the necessary facilities. I express my deepest gratitude to Metrochem labs Pvt, Hyderabad, for providing the API of Remogliflozin Etabonate to facilitate the work. I take my pleasure to thank all the teaching and non-teaching staff members for their valuable support during my academics and project.
