What condition is Metoprolol primarily used to treat?

Metoprolol is primarily used to treat high blood pressure and certain heart conditions. It is a beta-blocker that works by blocking the effects of adrenaline on the heart and blood vessels, thereby slowing the heart rate and reducing the force with which the heart pumps. This mechanism helps to lower blood pressure, making it beneficial for individuals with hypertension. Additionally, Metoprolol is effective in managing heart-related issues such as angina (chest pain) and in the prevention of heart attacks, particularly in patients who have a history of heart disease. The other conditions listed, such as respiratory distress, severe allergic reactions, and infections, are not treated with Metoprolol, as they require different classes of medications and interventions.
