Teoprolol is primarily used in the medical field as a beta-blocker. It is commonly prescribed to manage high blood pressure, helping to reduce the risk of heart attacks and strokes by relaxing blood vessels and easing the heart's workload. Additionally, it is effective in treating angina (chest pain) by improving blood flow to the heart and reducing its oxygen demand. Teoprolol is also utilized in managing irregular heart rhythms (arrhythmias) and can be part of the treatment plan for heart failure, improving overall heart function. In some cases, it is prescribed to prevent migraines or to manage symptoms of an overactive thyroid. Always used under medical supervision, it plays a crucial role in cardiovascular health management.
