In this Cochrane review, the authors quantified the effectiveness of four classes of antihypertensive medications i. In patients with moderate to severe hypertension i. However, only low-dose thiazide diuretics were effective; high-dose thiazide diuretics were no different than placebo in risk of mortality and cardiovascular events. In this situation, patients would need to be treated with thiazide diuretics or patients with beta blockers for five years to prevent one cardiovascular event.
Beta blockers did not show any ARR of cardiovascular events for secondary or primary prevention in patients with moderate to severe hypertension. Beta blockers and CCBs were also no different from placebo in reducing mortality risk. Thiazide diuretics and ACE inhibitors reduced total mortality risk significantly, but this risk reduction was smaller than that of cardiovascular events and stroke.
Beta blockers did not provide more benefit than other antihypertensives and were generally not tolerated as well. Beta blockers were as well tolerated as CCBs. The Cochrane review of first-line antihypertensive medications has a number of limitations, one of which is that it did not address any renal outcomes. This Cochrane review did not include any trials in which two first-line antihypertensives were compared with each other without a placebo or untreated control.
The strongest body of evidence indicates that for most patients with hypertension, thiazide diuretics are the best proven first-line treatment in reducing morbidity and mortality.
They are particularly effective in the secondary prevention of cardiovascular events in all patients with hypertension, and in the primary prevention of cardiovascular events in patients with moderate to severe hypertension. Current evidence does not support the use of beta blockers, particularly atenolol, as first-line treatment for hypertension. Although there is increasing evidence that ACE inhibitors and possibly CCBs may be equivalent to thiazide diuretics in reducing morbidity and mortality, the relative expense of these medications makes thiazide diuretics a more favorable first-line choice in patients who do not have contraindications for their use.

The central agonists follow a different nerve pathway than the alpha and beta-blockers, but accomplish the same goal of blood pressure reduction. These medications reduce blood pressure by blocking neurotransmitters in the brain. This blocks the smooth muscles from getting the "message" to constrict. These drugs are rarely used unless other medications don't help. Blood vessel dilators, or vasodilators, can cause the muscle in the walls of the blood vessels especially the arterioles to relax, allowing the vessel to dilate widen.
This allows blood to flow through better. Your donation funds research, education and advocacy efforts that are saving lives every day. Thank you!

Other steps include losing excess weight, exercising regularly, and drinking alcohol only in moderation, as shown in the table below. See what other steps you can take in our Guide to a Healthy Heart.
The table below shows how much you can lower your systolic upper blood pressure level by making these recommended changes. If a healthy diet and lifestyle changes alone don't lower your blood pressure enough, or if your levels are very high to begin with, you should consider medication.
The drugs used to treat high blood pressure are effective and relatively safe, and most are available as low-cost generics.
But they can cause side effects, as listed in the table below. Many doctors will recommend initial treatment with a group of drugs called thiazide diuretics, sometimes known as "water pills. In addition, they outperform all other types of high blood pressure drugs in reducing the risk of death from heart failure. Still, many doctors routinely prescribe other blood pressure medicines, including newer, more expensive ones. In addition to thiazide diuretics, the guidelines this report is based on recommend three types of drugs for potential initial treatment, or if a second or even third drug is needed to lower your blood pressure.
There are many individual drugs within each group, but studies do not show that any one drug is safer or more effective than another in each group. Among the recommended blood pressure drugs, the specific type of blood pressure medicine is usually less important than getting your pressure under control. Your race and age, health status, and other factors may influence which type of drug your doctor recommends. The latest guidelines on which this report is based also recommend against taking several other types of high blood pressure drugs as first-choice treatment.
So, if you are prescribed a drug from one of these groups as initial treatment, you should ask your doctor why. Black Americans experience better results—lower blood pressure and prevention of heart attacks, heart failure, strokes, and death—when they are given a thiazide diuretic or a CCB as first-line treatment. People with high blood pressure and kidney disease represent another special case. Because many black Americans with high blood pressure and kidney disease will need two or more medicines to reduce their pressure, a reasonable treatment choice is a thiazide diuretic plus an ACEI or ARB.
The combination can damage your kidneys. Another special case: If you have angina or coronary artery disease, have had a heart attack, or if you have certain heart-rhythm or heart muscle abnormalities, or heart failure, a beta blocker is the best choice if you are also given a high blood pressure diagnosis. Among them are metoprolol Toprol-XL and generic , nadolol Corgard and generic , and propranolol Inderal and generic.
No matter what drug or combination of drugs you take, several steps can minimize the chance of side effects and increase the likelihood that you'll stick with therapy:. Persistent dry cough, high potassium levels, reduced kidney function, and an uncommon allergic reaction angioedema especially in black Americans. The main goal of blood pressure treatment is to reduce the risk of heart attack and stroke. But the immediate goal is to lower blood pressure. To what level, though?
That said, the lower your blood pressure is toward normal, the better. What else you need to know about the latest blood pressure guidelines. While a diet rich in potassium and possibly calcium can help control blood pressure, it's unclear if supplements have the same effect.
And some recent research suggests that too much calcium from supplements might increase the risk of heart disease and other health problems. As for potassium, the form in supplements and salt substitutes might not have the same effect as the kind in foods. And too much of it, even from food, can cause problems for people with heart failure or kidney disease, and for those who take certain blood pressure drugs, including ACE inhibitors, angiotensin receptor blockers, and potassium-sparing diuretics such as spironolactone Aldactone and generic.
So talk with a doctor before increasing your intake. If you take diuretics, your doctor may prescribe a potassium supplement, because those medicines can lower potassium levels.
