Metoprolol fumarate is primarily used in the management of cardiovascular conditions. It is commonly prescribed to treat high blood pressure (hypertension), helping to reduce the risk of heart attacks, strokes, and kidney problems. Additionally, it is effective in managing angina (chest pain) by improving blood flow to the heart and reducing its workload. Metoprolol fumarate is also utilized in the treatment of heart failure, where it helps to slow the progression of the disease and improve symptoms. In cases of myocardial infarction (heart attack), it is often administered to prevent further heart damage and improve survival rates. Its ability to regulate heart rhythm makes it beneficial for certain arrhythmias as well.
