When your blood pressure stays too high, your heart and arteries work harder than they should. ARB medications, angiotensin receptor blockers, are a class of drugs that stop a hormone called angiotensin II from tightening blood vessels. Also known as angiotensin II receptor antagonists, they help relax your arteries so blood flows more easily—without the dry cough that often comes with ACE inhibitors. These drugs are one of the most common choices for treating high blood pressure, especially if you can’t tolerate ACE inhibitors or have conditions like diabetic kidney disease.
Common ARB medications, include losartan, valsartan, irbesartan, and telmisartan. Each works the same basic way, but some last longer, work better for certain people, or offer extra protection for kidneys or the heart. For example, losartan is often used first because it’s affordable and well-studied. Valsartan and telmisartan are popular for patients who also have heart failure or diabetes. Unlike beta-blockers or diuretics, ARBs don’t usually cause fatigue or low potassium—though they can raise potassium levels in some people, especially if you have kidney issues.
They’re also used when other blood pressure meds don’t work or cause side effects. Many people take them with a diuretic like hydrochlorothiazide to get better control. ARBs are not first-line for everyone—some guidelines still prefer ACE inhibitors or calcium channel blockers—but they’re a solid, reliable option with fewer side effects than older drugs. If you’ve been told you need to avoid ACE inhibitors because of a persistent cough, ARBs are often the next step.
They’re not magic. You still need to watch your salt intake, stay active, and check your blood pressure regularly. And while they’re generally safe, they can cause dizziness, especially when you first start or increase the dose. Never stop taking them suddenly—your blood pressure could spike. Pregnant women should avoid them entirely—they can harm a developing baby.
You’ll find posts here that compare ARBs to other hypertension drugs like Alpress, explain how they interact with other medications, and show how they fit into broader treatment plans for heart and kidney health. Some articles dive into how these drugs affect kidney function, why they’re used in diabetes, and what to do if your blood pressure doesn’t drop enough. Others look at real-world side effects, cost differences between brand and generic versions, and how to tell if you’re getting the right one for your body.
Whether you’re just starting on an ARB or have been on one for years, this collection gives you the facts—not marketing. No fluff. Just clear, practical info to help you understand what’s in your medicine cabinet and why it matters.
