Determination of Proton Pump Inhibitors by Spectrophotometric, Chromatographic and by Hyphenated Techniques: A Review
Abstract
A detailed review to analyze the anti ulcer proton pump inhibitor (PPI) drugs, particularly for determination of their concentration percentage (assay) by analytical methods developed on analytical instruments i.e., UV visible Spectrophotometer, High Performance Liquid Chromatography, Ultra Performance Liquid Chromatography, and Hyphenated techniques. The review includes literature survey of PPI drugs namely omeprazole (OPZ), lansoprazole (LPZ), pantoprazole (PPZ) rabeprazole (RPZ), dexlansoprazole (DLPZ), esomeprazole (EPZ), dexrabeprazole (DRPZ), ilaprazole (IPZ), and tenatoprazole (TPZ). The examined literature survey addressed chromatographic (HPLC and UPLC) and UV visible spectrophotometric methods with LC-MS/MS methods used in pure forms, pharmaceutical formulations, and human plasma and other biological fluids for their estimation. In case of validation parameters mostly Linearity, Recovery study, LOD and LOQ was considered and mentioned.
