What Are Angiotensin Receptor Blockers?
Medical terminology is full of acronyms like MRI and ARB. That second one, ARB, stands for angiotensin receptor blocker. An explanation which can sound as confusing as the three-letter version. This post breaks down what ARBs are, what they treat and what to pay attention to for your health.
ARBs Explained Simply
ARBs are a type of medication ordered by your provider, usually a primary care physician or cardiologist. They block hormones that tighten your blood vessels. ARBs help relax and widen blood vessels. And relaxed blood vessels let blood flow easier. The result for you is lower blood pressure.
What Do ARBs Treat?
ARBs often treat high blood pressure. However, there are other uses, too.
Here are conditions ARBs might treat or lower the risk of:
- Heart failure
- Kidney disease
- Heart attack
- Stroke
Your provider may prescribe ARBs if they believe an ARB will benefit your overall health profile. ARBs do not cure disease. They may help prevent the onset of health conditions and help keep existing conditions from getting worse.
ARBs and ACE Inhibitors: What's the Difference?
You might have heard about ACE inhibitors. If so, maybe you're wondering what the difference is between them and ARBs. Both can lower blood pressure. Both ease the effects of hormones that tighten blood vessels. They just do it in different ways.
One other difference is in side effects. Some people develop a dry cough with ACE inhibitors. When they do, it's common for a provider to switch them over to an ARB.
Angiotensin Receptor Blocker Side Effects
There are some common ARB side effects to look out for:
- Dizziness
- Headache
- Tiredness
- Stuffy nose
Most side effects are mild, and most people tolerate them pretty well. One thing to note is that you might feel dizziest after your first dose. Future doses might not make you feel as dizzy as that first time. ARBs can also slightly raise your potassium level.
Don't Stop ARBs on Your Own
If your blood pressure goes down or you start feeling better, it can be tempting to stop taking your ARBs. If you stop, your blood pressure will likely go back up. Always talk to your Baptist Health provider before you stop any medication.
