A systematic comprehensive review of literature for the analysis of the most recent antiulcer drugs and proton pump inhibitors (PPIs) by different chromatographic and electrophoretic methods are presented. The review includes literature from 1985 until 2015 on eight proton pump inhibitors; namely: omeprazole (OMZ), lansoprazole (LAN), pantoprazole (PAN), rabeprazole (RAB), esomeprazole (EMZ),
dexlansoprazole (DLAN), dexrabeprazole (DRAB), and tenatoprazole (TNB). The investigated literature survey covers most chromatographic and electrophoretic methods used for the assay of these drugs in pure forms, in combined mixtures, in pharmaceutical dosage forms, and in biological fluids.
