A simple, precise and economical second order derivative method has been developed for the estimation of Raloxifene in bulk and pharmaceutical formulations. In this method Raloxifene showed sharp peak at 288 nm when n= 1 and linearity was measured at 288 nm. It obeyed Beer’s law in the concentration range of 2-12 mcg/ml. The LOD and LOQ were found to be 0.32 mcg/ml and 0.98 mcg/ml respectively. A recovery of Raloxifene in tablet formulation was observed in the range of 99.38-100.60%. The proposed method is precise, accurate and reproducible and can be extended to the analysis of Raloxifene in bulk and pharmaceutical formulations.
