Development and Validation of Furosemide Quantification Method By 1H NMR

Abstract: Abstract:Furosemide is a potent diuretic used for treatment of edema, hypertension and renal disease, among others. In this work, a simple and accurate method using 1 H NMR has been developed for quantification of furosemide in pharmaceutical formulations. All evaluated parameters (selectivity, linearity, accuracy, precision, limit of detection and limit of quantification) showed satisfactory results. Five pharmaceutical formulations (tablets) were analyzed by the developed method and the method described in t… Show more

“…In the case of falsifications where there is the intentional addition of impurities or diluents, the quality of the medicinal product can be easily checked because the added organic components will show characteristic signals in the 1 H NMR spectra. The ability of NMR to detect unknown organic impurities means that it can be considered a universal detector capable of identifying counterfeit drugs [16]. NMR also stands out for being a nondestructive technique that uses a small amount of solvent, where the analyte of interest can be recovered by the solvent drying process.…”
