Angiotensin Receptor Blockers (ARBs) Overview

✔ What are they?
Medications that relax blood vessels by blocking angiotensin II, a hormone that causes blood vessels to constrict, leading to lower blood pressure.

✔ How to recognize them?
Many end in "-sartan" (e.g., losartan, valsartan, candesartan, irbesartan).

✔ How do they work?
Block angiotensin II → Relax blood vessels → Lower blood pressure and reduce heart strain.

✔ Easy trick to remember:
"Sartans Stop Squeezing" (ARBs prevent blood vessel constriction).

✔ Common uses:

• High blood pressure

• Heart failure

• Kidney protection in diabetes

• Stroke prevention
