Atorvastatin is primarily used to lower cholesterol levels in the blood. It works by inhibiting an enzyme in the liver that is responsible for producing cholesterol. This helps reduce the risk of heart disease, stroke, and other cardiovascular issues. It is often prescribed to patients with high levels of LDL cholesterol, commonly referred to as "bad" cholesterol, as well as those with a history of heart-related conditions. Additionally, it can be used to manage conditions like atherosclerosis, where plaque builds up in the arteries, and to stabilize plaque to prevent it from rupturing. Atorvastatin is also beneficial for individuals with diabetes or other risk factors for heart disease, as it helps improve overall cardiovascular health. Patients are usually advised to combine its use with a healthy diet and regular exercise for optimal results.
