A Simple dissolution test procedure for Lansoprazole pellets dosages has been proposed and high performance liquid chromatography analytical method was developed for the measurement of Lansoprazole Pellets dosage forms with U.V detection. The chromatographic system consisted of a Zodiac ODS 4.6mm× 150mm column, an isocratic mobile phase of 650ml phosphate buffer+350ml acetonitrile. The flow rate is 1ml /minute and effluent is tested at 286nm, The lansoprazole was eluted at about 5.681min with no interfering peak from additives used for preparation dosage form. The method was linear over the range of 10-150µg/ml
lansoprazole. The dissolution test was conducted in 500ml phosphate buffer pH7.6 with paddle stirring at 100 rotation per minute (RPM).Dissolution was found to be not less than 75% in 45 minutes. The proposed method was applied successfully for the measurement of Lansoprazole content in Pellets and for vitro dissolution studies.
