Key takeaways
Amlodipine (Norvasc) and Atenolol (Tenormin) are both medications used to treat high blood pressure and chest pain, but they belong to different medication classes. Amlodipine is a calcium channel blocker (CCB) that works by relaxing blood vessels, while atenolol is a cardioselective beta-blocker that slows down the heart rate. Amlodipine is also used for coronary artery disease, whereas atenolol is used to lower the risk of death after a heart attack. Amlodipine is typically taken once daily, with doses ranging from 5 mg to 10 mg, and is available in both tablet and liquid forms. Atenolol is also taken once daily, with doses ranging from 50 mg to 100 mg for high blood pressure, and up to 200 mg for chest pain. Both medications are available as a lower-cost generic. Common side effects of amlodipine include swelling of the hands and feet and tiredness, whereas atenolol can cause dizziness, cold hands and feet, and tiredness. Atenolol should not be stopped suddenly due to the risk of heart attack and stroke.
