Key takeaways
Enalapril (Vasotec) and Candesartan (Atacand) are both medications used to treat high blood pressure and heart failure, but they belong to different classes. Enalapril is an ACE inhibitor, which works by blocking a protein that tightens blood vessels, while Candesartan is an ARB that blocks a hormone called angiotensin II to relax blood vessels. Enalapril is taken once or twice daily and can cause a dry cough, which is a common side effect of ACE inhibitors. On the other hand, Candesartan is typically taken once or twice daily but is less likely to cause a cough, and may cause upper respiratory infections and back pain. Both medications can raise potassium levels and should not be used during pregnancy. Enalapril can be used in children as young as 1 month old, whereas Candesartan is approved for children starting at age 1. If you experience side effects or have concerns about these medications, consult your healthcare provider.
