Metoprolol is a medication from the beta-blocker class, used to treat various cardiovascular conditions. It is commonly prescribed for high blood pressure, angina (chest pain caused by reduced blood flow to the heart), heart failure, and for preventing heart attacks. It is also used to control heart rate in cases of arrhythmias, such as atrial fibrillation.

Metoprolol works by blocking beta-adrenergic receptors, thereby reducing heart rate, blood pressure, and the heart's oxygen demand. This helps reduce stress on the heart and prevent cardiovascular complications.

Side effects may include fatigue, dizziness, low blood pressure, bradycardia (slow heart rate), or gastrointestinal disturbances. In rare cases, depression, breathing difficulties, or allergic reactions may occur. It is important to take metoprolol as prescribed by a doctor, and the treatment should not be stopped abruptly, as this may worsen cardiac symptoms.
