What prescription medications treat high blood pressure?

If lifestyle changes aren't enough, more than 50 prescription drugs can treat high blood pressure. Most of them fall into one of the following categories: diuretics, angiotensin converting enzyme (ACE) inhibitors, angiotensin receptor blockers, alpha-blockers, calcium channel blockers, or beta-blockers. Although each group of drugs works in a different way, all are effective in lowering blood pressure. Some of the newer medications used to treat high blood pressure are actually combinations of these categories.

Your doctor will consider your medical history, current health, age, race, and the severity of your hypertension when choosing a medication that's right for you. Beta-blockers, such as atenolol (brand name Tenormin), and diuretics, such as >hydrochlorothiazide (Hydrodiuril), are often the first choice for people newly diagnosed with hypertension. ACE inhibitors, such as >lisinopril (Zestril), may be especially helpful for people who have diabetes. Likewise, beta-blockers may help people who've had a heart attack in the past. You may need to try several medications before you find the one that works best for you. Or you may need to use a combination of these medications to control your high blood pressure. Always talk to your doctor about which medication is best for you.
