10.22376/ijpbs.2019.10.1.p1-12 Volume 1 Issue 2 2010 (April - June) A simple and sensitive, HPLC method has been developed and validated for the quantitative estimation of repaglinide in its single component tablet formulations (2 mg). Determination was performed using a Thermo BDS C18 column with mobile phase phosphate buffer: acetonitrile (pH 6.0; 45:55, v/v), and ultraviolet (UV) detection at 288 nm. The method was validated in terms of linearity (10–60 µg/ml), precision (intra-day variation below 0.6, inter-day variation below 0.2), accuracy (97.9 to 100.1%), ruggedness (within 0.5%) and specificity. The limit of detection and limit of quantification for repaglinide were found to be 1 µg/ml and 3 µg/ml, respectively. The developed method was successfully used for the assay of repaglinide tablet formulations. The method is simple, sensitive and precise; it can be used for the routine quality control testing of marketed formulations.  lessThan br / greaterThan Meeta A. Jiladia,S. S. Pandya,Ashok G.
