Simple sensitive accurate uv spectroscopic methods was developed for the simultaneous estimation of Sildenafil Citrate And Dapoxetine Hydrochloride in pharmaceutical dosage form. In this communication absorbance ratio method (Q value) was reported for the assay of both the drugs in the pharmaceutical dosage form. In absorbance ratio method (Q value) the absorbance were measured at wavelengths 237 nm and 293 nm. The proposed method was validated statistically for specificity, linearity, accuracy and precision. Recoveries of methods were carried out by standard addition method. The low values of standard deviation and percentage RSD indicated high precision of methods. These methods were successfully used for routine analysis of Sildenafil Citrate and Dapoxetine Hydrochloride in combination dosage form with good recoveries.
