Stability Indicating RP-HPLC Method Development and Validation for the Determination of Solifenacin Succinate in Bulk and its Pharmaceutical Formulation

Abstract

The current work aims to establish a novel and advanced reverse phase isocratic liquid chromatography system followed by validation and to conduct stability analysis in active pharmaceutical ingredients and formulations for the quantification of Solifenacin Succinate. The optimized elution was achieved with column Sunfire C8 (4.6 x 150mm, 5µm), using the mobile phase of Buffer: Methanol: Acetonitrile in the composition ratio of 45:45:10 v/v. The wavelength of detection was selected as 220nm with 1.0ml/ min flow rate and 30μl injection volume. The retention time of Solifenacin Succinate was found 2.94 min respectively. The method developed has been validated for various analytical parameters according to ICH guidelines. The Linearity was attained at 20 to100 μg/ml of concentration range. The established method was proved as reproducible. The Assay was obtained as 100.40%. The degradation studies were carried out at all degradative conditions and the results of degradation studies denote that the current method was specific, reliable, and economical. Hence, the developed method can be applied for the qualitative and quantitative determination of the selected drug and its commercial formulations.
