A simple, sensitive and precise reverse phase high performance liquid chromatographic method has been developed for the simultaneous estimation of Losartan Potassium and Perindopril erbumine in pharmaceutical dosage form. The mobile phase consisted of ortho phosphoric acid: HPLC water: 55:45 0.1ml /10 min and wavelength of detection at 218 nm. The retention times of were Losartan Potassium and Perindopril erbumine 3.016 min and 3.43 min respectively. The method was validated in terms of linearity, precision, accuracy, limit of detection, limit of quantification. The method was found to be linear in the range of inertsil-ODS C18 (250 x 4.6mm, 5μ) g/ml for Losartan potassium and Perindopril erbumine respectively. The coefficient of variance for both the drug was more than 0.999.The proposed method can be used for determination of these drugs in combined dosage forms.
