Perindopril erbumine is primarily used in the treatment of high blood pressure (hypertension) and heart failure. It helps to relax blood vessels, allowing blood to flow more smoothly and reducing the workload on the heart. Additionally, it is prescribed to improve survival rates in patients who have experienced a heart attack. The medication is also effective in managing stable coronary artery disease by reducing the risk of cardiac events. It is often used as part of a long-term treatment plan to maintain cardiovascular health and prevent complications associated with these conditions.
