Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood. According to the Mayo Clinic [2], Lipitor works by blocking an enzyme in the liver that is responsible for producing cholesterol. This action leads to a decrease in the amount of cholesterol in the bloodstream. However, there is no evidence to suggest that Lipitor affects fat absorption.

The Drug Patent Watch [1] website provides information on the patent status of Lipitor, but does not offer any information on its side effects or how it works. The National Center for Biotechnology Information [3] states that atorvastatin is generally well-tolerated, with the most common side effects being muscle pain and weakness. However, there is no mention of any effects on fat absorption.

In conclusion, there is no evidence to suggest that Lipitor has any effect on fat absorption. Its primary action is to lower cholesterol levels in the blood by blocking an enzyme in the liver. As with any medication, there may be side effects, but these are generally well-tolerated and are not related to fat absorption.
