Metoprolol is widely used in the treatment of cardiovascular conditions. It is primarily prescribed to manage high blood pressure, helping to reduce the risk of heart attacks, strokes, and kidney problems. It is also effective in treating angina (chest pain) by improving blood flow to the heart and reducing its workload. Additionally, metoprolol is commonly used to control irregular heart rhythms (arrhythmias) and to improve survival rates following a heart attack. In some cases, it is prescribed to prevent migraine headaches or to manage symptoms of an overactive thyroid. Its ability to block certain stress hormones makes it a key medication in managing heart-related conditions.
