Compare Procardia XL vs. Lopressor

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Nifedipine ER (Procardia XL) and metoprolol tartrate (Lopressor) are both used to treat chest pain and high blood pressure, but they belong to different medication classes and work differently. Nifedipine ER is a calcium channel blocker that relaxes blood vessels to lower blood pressure and improve oxygen flow to the heart. In contrast, metoprolol tartrate is a beta blocker that slows down the heart, reducing the pressure on blood vessels and the heart's oxygen demand. Nifedipine ER is typically taken once daily, while metoprolol tartrate is usually taken twice daily with food. Common side effects of nifedipine ER include swelling in the legs, dizziness, and headaches, whereas metoprolol tartrate can cause tiredness, dizziness, and diarrhea. Additionally, metoprolol tartrate is also used to lower the risk of death after a heart attack, a benefit not shared by Nifedipine ER. Both medications are available in generic forms, making them more affordable options.
