Fluorescence spectroscopy method for estimation of Ivabradine in bulk and the tablet dosage form.

A simple and sensitive spectrofluorimetric method has been developed for the estimation of Ivabradine HCl in bulk and the tablet dosage form. Ivabradine HCl in methanol produces fluorescence at 325 nm (λem) with excitation at 287 nm (λex). The linearity range was found to be 100-500 ng/ml with a correlation coefficient of 0.999. The limit of detection (LOD) and limit of quantitation (LOQ) for the developed method were found to be 8.38 and 25.39 ng/ml, respectively. The developed method was found to be specific, sensitive, accurate, and precise. It was successfully used for the estimation of Ivabradine HCl in its tablet dosage form. The content of Ivabradine HCl in marketed formulations was found to be 101.25 ± 1.16 % of label claims. Copyright © 2021 Elsevier B.V. All rights reserved.
