Metoprolol is a beta-blocker used primarily for several cardiovascular conditions. Its main uses include:
- Treating high blood pressure (hypertension)
- Preventing chest pain (angina) in people with heart disease
- Reducing the risk of heart attack in individuals who have already experienced a heart attack
- Lowering the risk of hospitalization and death in people with heart failure
- Treating certain types of abnormal heart rhythms, like atrial fibrillation and atrial flutter
Metoprolol may also be prescribed for other conditions as determined by a healthcare provider, such as supraventricular tachycardia, migraine prophylaxis, or thyroid storm[1][2][3].
It works by blocking beta receptors in the heart, which slows the heart rate and lowers blood pressure. This mechanism can improve blood flow, reduce the heart’s workload, and help protect the heart in various cardiac conditions[1][4][6].
