Abstract
A Simple, precise and robust method for estimation of Esomeprazole
and Domperidone in combined capsule dosage form. The optimum
mobile phase contain Sodium dihydrogen phosphate: Methanol (80: 20
V/V). Esomeprazole and Domperidone showed linearity in the range of
32 - 96 μg/ml and 24-72 μg/ml respectively. Recovery studies were
carried out at 50%, 100%, 150% level and the amount recovered
101%, 98%, 99% respectively. The stability of the sample spiked with
drug was subjected to short term stability at room temperature (Initial
& after 8 hours) and the stability of the respective solution was
determined.
Keywords: Estimation, Domperidone, Esomeprazole, RP-HPLC.
