Key takeaways
Metoprolol tartrate (Lopressor) and benazepril (Lotensin) are both medications used to manage high blood pressure, but they belong to different classes and have distinct uses and side effects. Metoprolol tartrate is a beta blocker that slows down your heart rate and is also used to treat chest pain and reduce the risk of death after a heart attack. It is typically taken twice daily with food. On the other hand, benazepril is an ACE inhibitor that helps relax blood vessels and is usually taken once or twice daily, with or without food. Benazepril is noted for its potential to protect kidney function in people with diabetes or mild-to-moderate kidney disease, whereas metoprolol is preferred for those who have had a heart attack. While metoprolol can cause dizziness, tiredness, and may hide symptoms of low blood sugar, benazepril can cause a dry cough, dizziness, and should not be taken during pregnancy due to the risk of birth defects. Both medications are available in lower-cost generic forms.
