How it works
Amlodipine is used in the treatment of hypertension and chest pain (Angina).
Atenolol is used in the treatment of chest pain (Angina), arrhythmias, heart attack and hypertension.
Common side effects
Amlodipine is a calcium channel blocker. It blocks the action of calcium on the heart and blood vessels. This lowers the blood pressure, abnormally fast heartbeat and reduces strain on the heart following a heart attack.
Atenolol is a beta blocker that works specifically on the heart. It works by slowing heart rate and relaxing blood vessels to improve blood flow to the organ.
