Losartan is an angiotensin II receptor blocker (ARB) used to treat hypertension. The use of ARBs may be beneficial for patients who cannot tolerate the side effects of which class of medications?


• ACE inhibitors are often not tolerated due to the dry cough that many patients experience. ARBs provide a similar mechanism of action without the side effect of the dry cough 

• Beta blockers and loop diuretics all have a mechanism of action quite different from ACE inhibitors, so these are not the first choice for replacing ACE inhibitors that are not tolerated due to a cough
