Abstract
Impurities are either naturally occurring or added during synthesis of a chemical or commercial product. During production, impurities may be purposely, accidentally, inevitably, or incidentally added into the substance. Any impurities present drug substances can be addressed in its chemical and safety perspectives. 5 Bromo Nicoticnic Acid (5BNA) is basically a reactant impurity present in the Nicergoline (NCR). The present study aims to develop simple, sensitive, precise method to estimate the 5BNA impurity and perform the stress degradation study in NCR to screen the NCR stability in different stress conditions by using HPLC. The developed method was used as 25 mM phosphate buffer:acetonitrile as a mobile phase (50:50% v/v) with flow rate of 1 mL/min. Limit of detection and quantification were found out to be 1.15 and 3.5 ng/ml respectively. The method was liner over the range of 0.3-1.1 μg/ml. The forced degradation study described the nicergoline drug shows markable degradation in acid and alkali hydrolysis but it does not shows significant changes in chromatographic pattern. In case of the photo stability and oxidative degradation shows significant changes in the chromatogram. The new fractions apart from 5-bromo nicotinic acid were subjected to NMR structural analysis. The develop method can be useful to estimate the impurity in bulk drug and formulations. The developed method was validated as per ICH guidelines. The developed method has shown good repeatability and reproducibility.
