The uses of OLMEZEST include: Olmesartan is used for: Treating high blood pressure, alone or with other medicines.
Olmesertan controls high blood pressure. It works by blocking the effect of a hormone called angiotensin II. Unopposed, this substance prompts the blood vessels to contract, an action that tends to raise blood pressure.
Olmesertan relaxes and expands the blood vessels, allowing pressure to drop. Olmesertan may be prescribed alone or with other blood pressure medications, such as diuretics that help the body get rid of excess water. Olmesertan HCT provides just such a combination. It contains Olmesertan plus hydrochlorothiazide, a common diuretic that increases the output of urine. This removes excess fluid from the body and helps lower blood pressure.
Olmesartan is in a group of drugs called angiotensin II receptor antagonists. Olmesartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.
