Atorvastatin helps lower high LDL cholesterol, improve overall cholesterol balance, and reduce cardiovascular disease risk. It may be used as preventive therapy in people with atherosclerosis, coronary artery disease risk, diabetes-related heart risk, or a history of cardiovascular events. Atorvastatin is not a symptom-relief medication; it does not immediately treat pain, palpitations, or high blood pressure. Its benefit is mainly based on long-term vascular protection and risk reduction.
