ACE inhibitors, calcium channel blockers, diuretics, beta-blockers and angiotensin II receptor blockers are some of the medications used to treat high blood pressure, reports Mayo Clinic. Some people take more than one medication to keep their blood pressure under control.
ACE inhibitors prevent the blood vessels from narrowing, reducing the workload of the heart, explains the Texas Heart Institute. ACE inhibitors also reduce the amount of fluid and sodium in the body. Lisinopril, enalapril and ramipril are examples of ACE inhibitors, states Mayo Clinic.
Calcium channel blockers prevent calcium from entering the cells of the blood vessels and heart, notes Mayo Clinic. This allows the cells to relax, reducing blood pressure. Amlodipine is a commonly used calcium channel blocker. Diuretics reduce blood pressure by removing excess fluid and sodium from the body. Furosemide and hydrochlorothiazide are two diuretics used to treat high blood pressure, according to WebMD.
Beta blockers lower blood pressure by blocking certain signals sent to the heart and blood vessels, states Mayo Clinic. Atenolol and metoprolol are examples of beta blockers. Angiotensin II receptor blockers inhibit the effects of a hormone called angiotensin. Valsartan and losartan are two of the angiotensin II receptor blockers used to treat high blood pressure. Renin inhibitors such as aliskiren prevent an enzyme called renin from causing blood pressure to rise.
