Abstract
Validated high performance liquid chromatographic (HPLC) method for estimation of Torsemide (TOR) and Spironolactone (SPI) in tablet dosage form. Isocratic RP-HPLC separation was achieved on Licrosphere C18 column (250 x 4.6mm) using Methanol: Acetonitrile: Phosphate buffer, pH 6.5 (60:20:20 v/v) at flow rate of 1.5 ml/min at 30 oC temperature. Quantitation was achieved by UV detection at 252 nm over the conc. range 0-25 μg/ml for both the drugs with mean recoveries of 100.01% + 0.12 and 100.64% + 0.20 for TOR and SPI respectively. This method is simple, precise and sensitive and applicable for the simultaneous estimation of TOR and SPI in tablet pharmaceutical combined dosage form..
