How It Works
These medicines block the action of a
that causes blood vessels to narrow. As a
result, blood vessels may relax and open up. This makes it easier for blood to
flow through the vessels, which reduces blood pressure. Also, these drugs
increase the release of sodium and water into the urine, which also lowers
blood pressure.
Why It Is Used
Angiotensin II receptor blockers
(ARBs) may be used alone or combined with other medicine—often a diuretic—to
treat
.
ARBs may be used by
people who cannot take ACE inhibitor medicines. ACE inhibitors can cause an
annoying cough. This cough may be hard for some people to live with. So doctors
may prescribe an ARB instead. ARBs are less likely to cause a cough.
ARBs are also used by people have heart problems such as coronary artery disease or heart failure. ARBs might be used by people who type 2 diabetes and have early signs of kidney disease or who have kidney disease from diabetes (diabetic nephropathy).
How Well It Works
Angiotensin II receptor blockers
(ARBs) reduce blood pressure as effectively as angiotensin-converting enzyme
(ACE) inhibitors but are less likely to cause the cough that is associated with
ACE inhibitors.
If you are taking an ARB because you have diabetes and early signs of kidney problems, or have kidney disease, these medicines can slow or prevent further damage to your kidneys.
Side Effects
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.
Here are some important things to think about:
- Usually the benefits of the medicine are more important than any minor side effects.
- Side effects may go away after you take the medicine for a while.
- If side effects still bother you and you wonder if you should keep taking the medicine, call your doctor. He or she may be able to lower your dose or change your medicine. Do not suddenly quit taking your medicine unless your doctor tells you to.
