Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. According to the sources provided, there is no evidence to suggest that Lipitor affects fat absorption in the body.

DrugPatentWatch [1] provides information on Lipitor's active ingredient, atorvastatin, and its mechanism of action. It states that atorvastatin works by inhibiting an enzyme called HMG-CoA reductase, which is responsible for the production of cholesterol in the liver. By reducing the production of cholesterol, Lipitor can help to lower cholesterol levels in the blood.

The National Center for Biotechnology Information [2] also explains that atorvastatin works by inhibiting the production of cholesterol in the liver. However, it does not mention any effect on fat absorption in the body.

A study published in the Journal of Lipid Research [3] investigated the effects of atorvastatin on the absorption of dietary fat in rats. The study found that atorvastatin did not affect the absorption of dietary fat in the rats.

In conclusion, based on the sources provided, there is no evidence to suggest that Lipitor affects fat absorption in the body. Lipitor works by inhibiting the production of cholesterol in the liver, but it does not have any known effect on the absorption of dietary fat.
