Abstract
Background: Imeglimin HCL is a medication used in pharmaceutical products. To ensure its quality and effectiveness, it's crucial to have a reliable method to measure its concentration in these products. High-Performance Liquid Chromatography (HPLC) is a common technique for this purpose. Objective: This study aimed to develop and validate a precise and accurate stability indicating HPLC method for measuring Imeglimin HCL in pharmaceutical formulations. Methods: The method optimization process included selecting a suitable chromatographic column and determining the optimal mobile phase composition. A Credchrom C18 column (250mm x 4.6 mm x 5µm) was chosen, and a mobile phase consisting of Phosphate Buffer and acetonitrile (80:20, v/v) was identified as optimal. The selected conditions provided satisfactory resolution and a retention time of 2.5 minutes for Imeglimin HCL, with detection achieved at a wavelength of 241nm. Validation parameters, including linearity, precision, accuracy, limit of detection (LOD), and limit of quantification (LOQ), were thoroughly evaluated. Precision was assessed through %RSD values for repeatability and intra-day and inter-day precision. Accuracy was determined by % recovery, with values ranging from 98.00% to 102%. Subsequently, force degradation studies were conducted to further assess the method's stability. Results: The developed RP-HPLC method exhibited excellent linearity (R^2 close to 1) and sensitivity, with LOD and LOQ values of 0.577722 μg/ml and 1.750673 μg/ml, respectively. Precision, as indicated by %RSD values, ranged from 0.994733 for repeatability to 0.988377–0.7480963 for intra-day precision and 0.988377–10.9883477 for inter-day precision. Accuracy, reflected by % recovery, was within acceptable limits (98.62–100.34%). These results, along with successful force degradation studies, confirmed the method's reliability and stability. Conclusions: In conclusion, the developed RP-HPLC method offers a sensitive, precise, and accurate means for the estimation of Imeglimin HCL in pharmaceutical formulations. Its robustness and stability make it suitable for routine analysis in pharmaceutical laboratories, ensuring the quality and efficacy of Imeglimin-containing products.
