A simple, economic, selective, precise, and stability-indicating Reverse phase High Performance Liquid Chromatography method for analysis of Vardenafil and Dapoxetine HCl was developed and validated according to ICH guidelines. The quantification of the drug was carried out using Hypercil BDS C18 250mm × 4.6mm × 5μm or its equivalent in isocratic mode, with mobile phase compressing of Buffer (KH2PO4): Acetonitrile: Triethylamine (55: 45: 0.1 v/v/v) the flow rate was 1ml/min and the detection was carried at 266 nm. The retention time for Vardenafil and Dapoxetine HCl was found to be 3.673 and 5.070min respectively. The percent assay for Vardenafil and Dapoxetine HCl was found to be 100.22% and 99.44% respectively. The method was also applied for the determination of Vardenafil and Dapoxetine HCl in the presence of their degradation products formed under variety of stress conditions. Proposed method was validated for precision, accuracy, linearity range, specificity and robustness.
