An investigative review for pharmaceutical analysis of angiotensin receptor blockers: Olmesartan medoxomil.

Hypertension is often asymptomatic and can substantially elevate the risk of cardiovascular complications. Olmesartan medoxomil works by competitively blocking the angiotensin II receptors, preventing angiotensin II from constructing the blood vessels and releasing aldosterone. This discussion is focused on the critical analytical methods used to analyze olmesartan medoxomil in pharmaceutical and biological samples. A variety of analytical methods have been employed to both qualitatively and quantitatively determine the analyte, including high-performance thin-layer chromatography (HPTLC), high-performance liquid chromatography (HPLC), voltammetry, capillary zone electrophoresis, UV/Vis spectrophotometry, and 96-microwell assays. The review also includes official methods published in the Indian Pharmacopoeia. Based on existing literature, simple spectrophotometry and liquid chromatography are commonly used to analyze olmesartan medoxomil. These findings provide a solid foundation for future olmesartan medoxomil drug analysis research.
