The aim of present study to develop methods for estimation of gabapentin in pharmaceutical dosage forms. Distil water is used as a solvent so methods are called green analytical methods. Absorption minima in first order derivative spectra was found to be 220 nm (method-A) and area under curve was measured from 200-210 nm (method-B) and 200-280 nm (method-C), the drug followed a linear relationship in the range of 100-600 μg/ml while the correlation coefficient was at 1.0, 0.999 and 1.0 respectively. The recovery was 99.52% ±0.56(method-A) and the coefficient of variance for intraday and interday was found to be less than 2%, LOD and LOQ for this method was found 25 μg/ml and 83 μg/ml(method-C) respectively. This method is found suitable for day to day analysis of GBP in tablet dosage form.
