Analytical method validation for estimation of avanafil and dapoxetine hydrochloride tablet dosage form by HPTLC method

Objective: A simple, specific, accurate and precise RP-HPTLC method has been developed and validated for simultaneous estimation of Avanafil and Dapoxetine. Methods: The chromatographic separation was achieved on Aluminium plates precoated with Silica gel 60 F254 using chloroform: methanol: ethyl acetate: glacial acetic acid (5:2:3:0.2, v/v/v/v) as mobile phase detected at 279 nm. Results: The correlation coefficient for RP-HPLC method was found to be 0.9987 for Avanafil and 0.9991 Dapoxetine and the linearity range was found to be 1040-3640 ng*spot-1 for Avanafil and 80-280 ng*spot-1 for Dapoxetine. Conclusions: The developed method was successfully applied to marketed tablet dosage form and the results were found with higher confidence.
