How does Irbesartan work?
Irbesartan is an ARB that works by blocking the action of angiotensin II, a substance in the body that narrows blood vessels [1]. By preventing this substance from acting, Irbesartan allows blood vessels to relax and widen, which lowers blood pressure and improves blood flow [1].

Common side effects of Irbesartan can include dizziness, fatigue, and nausea [1]. More serious, though less common, side effects may include kidney problems, liver problems, and allergic reactions [1].
How does Irbesartan compare to other blood pressure medications?
Irbesartan belongs to a class of drugs called ARBs. Other classes of blood pressure medications include ACE inhibitors, calcium channel blockers, and diuretics, each working through different mechanisms [3]. The choice of medication depends on individual patient factors, including the severity of hypertension, other medical conditions, and potential side effects [3].
