An Improved Rp-HPLC Method for the Quantitative Determination and Validation of Levetiracetam in Bulk and Pharmaceutical Formulation

Abstract

The present study depicts the development of a validated RP-HPLC method for the determination of the Levetiracetam in pharmaceutical tablet dosage form. RP-HPLC method was developed by utilizing Welchrom C18 Column (250 x 4.6 mm, 5µ), Shimadzu LC-20AT Prominence Liquid Chromatograph. The mobile phase composed of 10 mM Phosphate buffer: acetonitrile (50:50 v/v) (pH-3.0, adjusted with triethylamine). The flow rate was set to 1.0 ml/min with the responses measured at 243.2 nm using Shimadzu SPD-20A Prominence UV-Visible detector. The retention time of Levetiracetam was found to be 3.030 minutes. Linearity was established for Levetiracetam in the range of 10-50 µg/ml with correlation coefficient 0.9998. The LOD and the LOQ for Levetiracetam found to be 0.468 μg/ml and 1.421 μg/ml respectively. The amount of Levetiracetam present in the formulation was found to be 99.56 %. None of the excipients interfered with the analyte of interest. Considering all the results of validation parameters simplicity of the method and the cost effectiveness of the overall procedure, it is possible to conclude that the developed method can be suitable for the regular quality control determination of Levetiracetam in bulk as well as pharmaceutical dosage form.
