Key takeaways
Diltiazem (Cardizem) and metoprolol tartrate (Lopressor) are both used to treat chest pain, but they belong to different medication classes. Diltiazem is a calcium channel blocker (CCB) that works by slowing your heart rate and relaxing your blood vessels, while metoprolol tartrate is a beta blocker that slows down the heart to reduce pressure on blood vessels. Diltiazem is taken four times a day, whereas metoprolol tartrate is typically taken twice daily. Diltiazem is mainly used for chest pain, while metoprolol tartrate also treats high blood pressure and lowers the risk of death after a heart attack. Common side effects of diltiazem include swelling in the legs and dizziness, while metoprolol tartrate can cause tiredness and dizziness. Both medications are available in generic forms, making them more affordable options.
