RP-HPLC Method Development and Validation for the Estimation of Mirabegron in Bulk and Dosage Form
A new, simple, precise, accurate and reproducible Reverse Phase High Performance Liquid Chromatography (RP-HPLC) method for Simultaneous estimation of bulk and pharmaceutical formulations. Separation of Mirabegron was successfully achieve , C18, 250X4.6mm, 5µm or equivalent in an isocratic mode utilizing methanol water (70:30) at pH 5.0 Adjusted to OPA at a flow rate of 1.0ml/min and eluate was monitored at 243nm, with a retention time of 2.584 minutes for Mirabegron. The method was validated and the response was found to be linear in the drug concentration range of 50µg/ml to150 µg/ml for Mirabegron. The values of the correlation coefficient were found to 0.999for Mirabegron. The Limit of Detection(LOD) and Limit of Quantification (LOQ) for Mirabegron were found to be 0.149 and 0.498 respectively. This method was found to be good percentage recovery were found to be 99 indicates that the proposed method is highly accurate. The specificity of the method shows good correlation between retention times of standard with the sample so, the method specifically determines the analyte in the sample without interference from excipients of tablet dosage forms. The method was extensively validated according to International Council for Harmonisation(ICH) guidelines for Linearity, Accuracy, Precision, Specificity and
