Olmesartan is a medication primarily used to treat high blood pressure [1]. It belongs to a class of drugs called angiotensin II receptor blockers (ARBs) [1].
How does olmesartan work to lower blood pressure?
Olmesartan functions by blocking the action of angiotensin II, a hormone that constricts blood vessels [1]. By preventing this constriction, olmesartan allows blood vessels to relax and widen, which in turn lowers blood pressure [1].

Common side effects associated with olmesartan include dizziness, lightheadedness, and fatigue [3]. Less frequently reported side effects may involve nausea, diarrhea, and muscle pain [3]. A notable and rare but serious side effect is olmesartan medoxomil-associated enteropathy, which can cause severe chronic diarrhea and significant weight loss [4].
