Which medicines use an angiotensin II receptor antagonist (ARB) for hypertension?
An angiotensin II receptor antagonist (ARB) is a class of blood-pressure medicines. Common ARBs include telmisartan, losartan, valsartan, irbesartan, candesartan, and olmesartan.
Where does “-sartan” come from?
Many ARB brand and generic names end in “-sartan.” That naming pattern is used because these drugs all block the angiotensin II type 1 (AT1) receptor, which helps relax blood vessels and lower blood pressure.
Who manufactures them (examples by manufacturer/brands)?
The same ARB molecule is often made by multiple companies (including generic manufacturers). Brand names depend on country, but examples include:
- Losartan (e.g., Cozaar is a well-known brand name)
- Valsartan (e.g., Diovan)
- Telmisartan (e.g., Micardis)
- Irbesartan (e.g., Avapro)
- Candesartan (e.g., Atacand)
If you tell me your country or the exact “-sartan” name you saw, I can identify the specific medicine and the most common brand(s) associated with it there.
What is the difference from ACE inhibitors?
ARBs lower blood pressure by blocking the angiotensin II receptor. ACE inhibitors lower angiotensin II production instead. ARBs are often used when a patient can’t tolerate ACE inhibitors (for example, due to cough).
