Key takeaways
Candesartan (Atacand) and ramipril (Altace) are both medications used to treat high blood pressure, but they belong to different classes. Candesartan is an angiotensin II receptor blocker (ARB), while ramipril is an angiotensin-converting enzyme (ACE) inhibitor. Both medications work by relaxing blood vessels, but they do so in different ways. Candesartan blocks the action of angiotensin II, a hormone that narrows blood vessels, whereas ramipril blocks a protein in your body that tightens blood vessels. Candesartan is available in both brand and generic forms, while ramipril is only available as a generic. Ramipril can cause a dry cough, which is less common with candesartan. Both medications can cause dizziness and high potassium levels, and neither should be used during pregnancy. Candesartan can be used in children, but ramipril is for adults only.
