Olmesartan is commonly used to treat high blood pressure. Although it is not a cure, the drug does cause blood vessels to relax, allowing more blood to flow from the heart to the rest of the body and lowering blood pressure. It is usually taken on a daily basis, and, as with any medication, side effects, such as dizziness, are possible.
Olmesartan is part of a class of drugs called angiotensin II receptor blockers, or ARBs for short. As the name implies, it blocks angiotensin II receptors. This decreases the effectiveness of a chemical known as angiotensin II, which normally causes blood vessels to narrow (constrict). By blocking the effects of angiotensin II, the medication causes blood vessels to relax, which can lower blood pressure.
