ABSTRACT
* A simple, specific, accurate and stability-indicating reversed phase high performance liquid chromatographic method was developed for simultaneous estimation of Tadalafil and Dapoxetine HCL, Water Symmetry C-18 (150 x 4.6 mm),5 µ and a mobile phase composed of Buffer : Acetonitrile (65:35)

* The retention time of Tadalafil and Dapoxetine HCL were found to be10.08 and 4.45 min respectively. Linearity was established for Tadalafil and Dapoxetine HCL in the range of 8.0-60 μg/ml and 24.0-180.0 μg/ml respectively. The percentage recovery of Tadalafil and Dapoxetine HCL were found to be in the range of 99.7-100.6% and 98.07-99.09% respectively. The drug was subjected to acid and alkali hydrolysis, oxidation, dry heat and photolytic degradation. The degradation studies indicated, Tadalafil showed degradation in acid and alkali while it was found stable in H₂O_2, photolytic and in presence of dry heat and Dapoxetine showed degradation in thermal and peroxide while it was found stable in rest of parameters . The degradation products of Tadalafil and Dapoxetine HCL in acidic, alkaline conditions were well resolved from the pure drug with significant differences in their retention time values. This method can be successfully employed for the quantitative analysis of Tadalafil and Dapoxetine HCL in bulk drugs and formulations.
