A fast, simple and economical spectrophotometric method has been used for the assay of different brands of enalapril maleate available in Karachi. We have compared the assay of the five brands. This analysis is based on UV absorbance at about 220nm wavelength. In this method distilled water was used as a solvent. The standard solution was made by dissolving 10 mg of enalapril maleate in 100 ml water. Similarly the sample drugs were dissolved in small amount of water and then it was diluted to make 100 ml. The absorbance was measured at 220 nm and then assay was determined by comparing the assay of available brand. Our study revealed that only two brands shows percentages within limits as compared to standard.
