Analytical method development & validation play important roles in the discovery development & manufacture of pharmaceuticals. Reversed phase HPLC (RP-HPLC) has a non-polar stationary phase and an aqueous, moderately polar mobile phase. A mixture of buffer solution and methanol in the ratio of (45:55). Drugs showed maximum absorbance at 280 nm for Dutasteriod and 225 nm for Tamsulosin. The % Accuracy is within limit (98.0 – 102.0 %) with %RSD less than 2%. The Precision RSD of Assay of six sample preparations was found to be 2.0%. The correlation coefficient value should not be less than 0.995 over the working range. The validation was performed as per International Conference on Harmonization (ICH) guidelines.
