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.

Introduction
Gene therapy by small interfering RNAs (siRNAs) hasbeen emerging as innovative nucleic acid medicines with increasing knowledge on the molecular mechanisms of endogenous RNA interference. Gene silencingis a promising tool for the treatment of numerous human diseases that cannot be cured by rational therapies. The primary success of siRNA applications depends on suitable vectors to deliver therapeutic genes.

Soranus was a Greek physician from Ephesus in 1st and 2nd century. He practiced in Alexandria and subsequently in Rome, and was one of the chief representatives of the Methodic school of medicine. Several of his writings still survive most notably his four-volume treatise on gynaecology and a Latin translation of his on acute and chronic diseases. He belonged to the Methodic School and was one of the most eminent physicians of that school.
