Abstract

In the present research, hydrotropic solubility enhancement has been done helpful for soluble poorly water soluble anti hypertensive drug is atorvastatin. The hydrotropic substance is urea. This technique is reliable and simple. In the present study more than 2 folds solubility enhanced when compared to distilled water alone. The urea was used in different concentrations 10, 20,30,40,50 and 60mg. The drug and hydrotropic substance ratios were 1:1, 1:2, 1:3, 1:4, 1:5 and 1:6. The hydrotropic substance (urea) did not interfered in the analysis. The hydrotropic substances are freely available, less cost, pollutant free method. The hydrotropic solubility enhancement technique is very accurate, the solubility enhancement further helpful for improve bioavialabity of drug.

Keywords: Atorvastatin, Urea, Hydrotropic technique, Solubity enhancement.
