A new, simple, rapid, accurate, precise and sensitive method has been developed for the simultaneous estimation of Furosemide and Spironolactone in their combined tablet dosage form. The method was carried out on a Hiber C18 column (250 mm×4.6mm, i.d.5 μm) with a mobile phase consisting of acetonitrile: water at a flow rate of 1 ml/min and the detection was carried out at 237 nm. The retention time of Furosemide and Spironolactone was 3.81 min and 7.28 min. respectively. Linearity for Furosemide and Spironolactone were found in the range of 2-10 μg/ml and 5-25 μg/ml respectively. The developed method was validated in terms of linearity, accuracy, and precision, limit of detection (LOD) and limit of quantification (LOQ). The proposed method can be used for estimation of both drugs in their combined dosage form.
