Hydrotropic agents have been employed to increase the aqueous solubility of poorly water soluble drug. This procedure eliminates the limitation of organic solvent such as methanol, ethanol, alcohol, dimethyl formamide, acetonitrile, hexane, acetone used in spectroscopic determination. The problems included are their high cost, toxicity and error (due to volatility). Use of hydrotropic solution for solubilization is a new simple, economic, rapid, accurate and reproducible spectrophotometric estimation method developed using 8M urea for solubilization and determination of simvastatin. Simvastatin was found to be poorly water soluble drug and there was more than 5 times increase in the solubility using 8.0 M urea solution. Urea did not interfere in the spectroscopic determination of simvastatin (lmax-223). Recovery studies and statistical data proved the accuracy, reproducibility and the precision of the proposed method.
