What Is Metoprolol Succinate Used For?
Many conditions related to the heart and blood vessels can be treated with metoprolol succinate, including high blood pressure, congestive heart failure, and angina symptoms. Although the medication is not licensed for use in children, it may be used off-label to treat several conditions seen in children. For example, metoprolol succinate may be used to slow the progression of aortic dilation in children with Marfan syndrome.
Metoprolol succinate (Toprol-XL®) has been licensed to treat a number of conditions. These uses for metoprolol succinate include:
High Blood Pressure
A blood pressure reading consists of two numbers (for example, 120/80). The top number is known as the systolic blood pressure, and the bottom number is the diastolic blood pressure. High blood pressure (hypertension) is defined as an average blood pressure higher than 140/90 with multiple readings.
In clinical studies, metoprolol succinate has been shown to significantly lower systolic and diastolic blood pressure. The higher the dose, the greater the drop in blood pressure is expected to be. By lowering blood pressure, metoprolol succinate can decrease the risks that occur with long-term high blood pressure (see Effects of High Blood Pressure). The medication does not, however, cure high blood pressure.
Angina is a type of heart disease that occurs when the heart muscle is not getting enough nutrient- and oxygen-rich blood for a short time. The inadequate blood flow is caused by narrowed coronary arteries (the blood vessels that supply blood to the heart). Chest pain is the most common symptom that occurs (see Angina Symptoms).
Metoprolol succinate is effective at treating symptoms of angina, decreasing the number of attacks, and improving exercise tolerance. It is effective at doing these things because it decreases the workload of the heart. This, in turn, means that the heart needs less oxygen- and nutrient-rich blood to function properly at any given level of effort. The medication does not cure this type of heart disease, however.
