    A stability-indicating HPLC-UV method for the simultaneous determination of sildenafil citrate and dapoxetine hydrochloride in solution and tablet was developed. The mobile phase was comprised of acetonitrile and 0.2M ammonium acetate buffer. The analyte was eluted at 3.392min and 7.255min for sildenafil citrate and dapoxetine HCl respectively using gradient system at a flow rate of 1.5mL/min. The theoretical plates count was>2000, tailing factor sildenafil citrate and dapoxetine HCl respectively. The drug solution was stable at ambient room temperature (26˚C) for 48hours.Both drugs were found susceptible to oxidation and the drug content dropped slightly in acid and alkali condition but stable under UV light and heat. No interference from tablet excipients and degradation products was found.
