What are ARBs and how do they differ from ACE inhibitors?

Angiotensin two receptor blockers, or ARBs, lower blood pressure by blocking the angiotensin two receptor directly rather than preventing its formation. Common ARBs include losartan, valsartan, irbesartan, and candesartan, all ending in the suffix "sartan." ARBs produce similar blood pressure reduction as ACE inhibitors but rarely cause the dry cough because they do not increase bradykinin levels. ARBs are prescribed for hypertension, heart failure, and diabetic kidney disease, especially for patients who developed a cough on ACE inhibitors. ACE inhibitors and ARBs should not be used together.
