How does TRIBENZOR work?

TRIBENZOR is a combination of three medications that lower blood pressure. Olmesartan is an angiotensin II receptor blocker (ARB). Angiotensin II is a hormone that normally attaches to its signaling proteins (receptors) in the body to raise your blood pressure. Olmesartan blocks this interaction from happening to lower your blood pressure. Amlodipine is a calcium channel blocker (CCB). It works by relaxing your blood vessels to lower your blood pressure. Hydrochlorothiazide is a thiazide diuretic (water pill). It works in your kidneys to remove extra water and certain electrolytes, like sodium and potassium. This helps lower blood pressure.
