Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body [1]. The drug works by inhibiting an enzyme called HMG-CoA reductase, which is responsible for producing cholesterol in the liver [2]. By reducing cholesterol production, Lipitor can help prevent the buildup of plaque in the arteries and lower the risk of heart disease.

Regarding the relationship between Lipitor and fat absorption, there is limited information available in the provided sources. However, a study published in the Journal of Lipid Research suggests that statins, including atorvastatin, may reduce the absorption of dietary fat in the intestines [3]. The study found that statins inhibited the activity of a protein called microsomal triglyceride transfer protein (MTP), which is necessary for the absorption of dietary fat in the intestines.

While the study provides some evidence for the potential effect of statins on fat absorption, it is important to note that the study was conducted in rats and further research is needed to determine the relevance to humans. Additionally, the study did not specifically investigate the effects of Lipitor on fat absorption, so it is unclear if the drug has the same effect as other statins.

In summary, while there is some evidence to suggest that statins may reduce fat absorption in the intestines, there is limited information available on the specific effects of Lipitor on fat absorption. Further research is needed to fully understand the relationship between Lipitor and fat absorption.
