Abstract

A simple sensitive and specific high performance liquid chromatography (HPLC) method was developed for the determination of esomeprazole in capsules and human plasma. Lansoprazole was used as an internal standard. Separation of Esomeprazole and internal standard was carried out on reverse phase C 18 column (250 x 4.6 mm, 5μ) using mobile phase acetonitrile and 20mM phosphate buffer pH 3.2 (30:70v/v) and UV visible detection at 300 nm without interference from endogenous materials. The method involves simple extraction procedure prior to chromatographic analysis. The method showed good linearity, accuracy and precision in both the lower and higher ranges of calibration in capsules and plasma. The limit of detection and quantitation of Esomeprazole in plasma was 10 ng/ml and 20 ng/ml respectively.
