An extensive survey of the literature published in various analytical and pharmaceutical chemistry
related journals has been conducted and the instrumental analytical methods which were developed
and used for determination of proton pump inhibitors in bulk drugs, formulations and biological fluids
have been reviewed. This review covers the time period from 1990 to 2011 during which 80 analytical
methods including all types of spectrophotmetric and chromatographic techniques were reported.
HPLC with UV detection was found to be the technique of choice for many workers and more than 50
methods were based on LC and UV. A critical analysis of the reported data has been carried out and
the present state-of-art of the analytical techniques for determination of omeprazole, esomeprazole,
pantoprazole, rabeprazole, dexrabeprazole, tenatoprazole, lansoprazole and dexlansoprazole has been
discussed.
