Lipitor is a medication that is commonly prescribed to help lower cholesterol levels in the body [2]. The active ingredient in Lipitor is atorvastatin, which works by blocking an enzyme that produces cholesterol in the liver [3]. By reducing the amount of cholesterol produced by the liver, Lipitor can help to lower LDL (bad) cholesterol levels in the blood, which can reduce the risk of heart disease, stroke, and other related conditions [3].

Lipitor is typically prescribed to individuals who have high levels of LDL cholesterol, which can be caused by a variety of factors including genetics, diet, and lifestyle [2]. It may also be prescribed to individuals who have a history of heart disease, stroke, or other related conditions, as it can help to prevent future occurrences [3].

It is important to note that Lipitor is not a cure for high cholesterol and should be used in conjunction with a healthy diet and exercise regimen [3]. Additionally, Lipitor may not be appropriate for everyone and should only be taken under the guidance of a healthcare professional [2].
