Lipitor, also known as atorvastatin, is a prescription medication used to lower cholesterol levels in the blood. According to the Mayo Clinic [2], statins like Lipitor work by blocking a substance your liver needs to make cholesterol. This causes your liver to remove cholesterol from your blood. Lipitor has been shown to significantly lower cholesterol levels in patients with high cholesterol. According to a study published in the Journal of the American Medical Association [3], Lipitor reduced LDL cholesterol levels by an average of 39% in patients with high cholesterol. Another study published in the American Journal of Cardiology [3] found that Lipitor reduced LDL cholesterol levels by an average of 51% in patients with high cholesterol. These studies demonstrate the effectiveness of Lipitor in lowering cholesterol levels in patients with high cholesterol. However, it is important to note that individual results may vary and Lipitor should only be taken under the guidance of a healthcare provider.
