Application of Analytical Tools and Techniques for Estimation of a Proton Pump Inhibitor (Esomeprazole Magnesium Trihydrate): A Comprehensive Review

The application of various sophisticated analytical tools and techniques is essential for estimating an active pharmaceutical ingredient present in either biofluids or pharmaceutical dosage forms. Reporting the multiple analytical methods used to quantify esomeprazole magnesium trihydrate, a proton pump inhibitor, is the ultimate goal of this review article. This article deals with a detailed discussion of different reported analytical procedures along with their pros and cons and their relevant criteria for quantifying the drug. Various analytical techniques like UV-Visible spectrophotometry, HPLC, HPTLC, hyphenated techniques, etc., are developed to assess the esomeprazole magnesium trihydrate in bulk materials, different pharmaceutical formulations, and biological matrices. Literature survey confirmed that the hyphenated techniques and chromatographic techniques are the best tools for biological matrices. Spectroscopic methods like UV and visible techniques are widely used for pharmaceutical matrices. All of the reported methods are accurate, precise, costeffective, and sensitive.
