Development and Validation of RP-HPLC Method for the Simultaneous Determination of Rabeprazole Sodium and Itopride Hydrochloride in Solid Dosage Form
A simple, sensitive, precise, accurate, rapid and reproducible reverse phase high performance liquid chromatographic procedure is developed for simultaneous determination of rabeprazole sodium and itopride hydrochloride in solid dosage form. The mobile phase used was a combination of acetonitrile: buffer (35:65 v/v) and the pH was adjusted to 7.0 ± 0.1 by addition of triethylamine. The detection of the capsule dosage form was carried out at 266 nm and a flow rate employed was 1 mL/min. Linearity was obtained in the concentration range of 2 to 16 μg/mL of rabeprazole sodium and 5 to 55 μg/mL of itopride hydrochloride with a correlation coefficient of 0.9992 and 0.9996 respectively. The results of the analysis were validated statistically and recovery studies confirmed the accuracy of the proposed method.
