Atorvastatin

Atorvastatin

Atorvastatin is a prescription drug available in the form of an oral tablet. Doctors prescribe Atorvastatin to lower cholesterol levels in individuals diagnosed with high cholesterol. Along with medication, your doctor may also suggest modifications to your diet and workout routine to manage cholesterol levels effectively.

This medication is also prescribed to reduce the likelihood of heart attacks and strokes. It can be beneficial for individuals with existing heart disease or those who are at risk of developing heart-related conditions.

Atorvastatin is classified under a group of medications known as statins. Its mechanism of action involves slowing down the body's cholesterol production.

What are the uses of Atorvastatin?

Atorvastatin is commonly prescribed to lower "bad" cholesterol (LDL) and lipids in the bloodstream while increasing "good" cholesterol (HDL). This medication works by reducing the production of cholesterol by the liver. Lifestyle changes such as regular exercise, weight loss if needed, and quitting smoking can improve the effectiveness of Atorvastatin. A balanced diet, i.e. low in cholesterol and fat, is also crucial. It is advised to visit a doctor for further details on using Atorvastatin to manage cholesterol levels.
