Question: 1 / 400

Which medication class is used when patients cannot tolerate ACE inhibitors?

Beta blockers

Angiotensin receptor blockers

Angiotensin receptor blockers (ARBs) are typically prescribed for patients who cannot tolerate ACE inhibitors due to side effects such as cough or angioedema. Both classes of medications act on the renin-angiotensin system, but ARBs provide a similar beneficial effect on blood pressure and heart function without the common adverse reactions associated with ACE inhibitors.

While beta blockers, calcium channel blockers, and diuretics have their specific roles in managing hypertension and heart conditions, they do not provide the same mechanism of action or specific benefits associated with the inhibition of angiotensin II as ARBs do. Therefore, when a patient experiences intolerance to ACE inhibitors, switching to an ARB allows for continued management of cardiovascular risks without the compounding effects of unacceptable side effects.
