Liquid chromatographic methods for the analysis of canagliflozin: concise overview and greener assessment

Abstract

There is a pressing need for the development of greener liquid chromatographic bioanalytical methods for antidiabetic drugs for plasma monitoring and revisiting patients' dosage regimens. Besides, analytical methods are also needed for the quality assurance of finished drug products and regulatory approval. Therefore, the present review focuses on the reported liquid chromatographic methods (LC and LC-MS/MS) that are applied for quality control, forced degradation, and pharmacokinetic studies of a newer antidiabetic agent, canagliflozin (CNG). These reported studies are summarized based on liquid chromatographic separation parameters, such as column dimensions, mobile-phase compositions, flow rate, and use of different detection systems (UV, PDA, and mass spectrometry). The sample pretreatment of biological fluids, which is important for minimizing the matrix effect, is dealt with separately. Liquid–liquid extraction was found to be the most preferred methodology adopted for sample pretreatment followed by the solid-phase extraction technique. However, miniaturized novel pretreatment methods are untraceable in the literature for the extraction of CNG. Special emphasis is paid to the assessment of the greenness profiles of the reported analytical methods for the consideration of sustainable development and green analytical chemistry. Based on the National Environmental Method Index (NEMI) assessment tool, most of the reported studies fulfilled around half of the parameters and were found to be about 50% greener. It is proposed that toxic or hazardous solvents, such as acetonitrile or methanol, should be replaced with greener and environmentally friendly solvents. Thus, there is a need to develop more robust, efficient, and greener liquid chromatographic methods for the determination of CNG in biological fluids and drug products.
