Based on the available information, there is no evidence to suggest that Lipitor, a medication used to treat high cholesterol, directly affects protein absorption rates.

The first source, a drug patent watch website, provides information on Lipitor's patent status and manufacturers but does not include any data on protein absorption rates.

The second source is a study published in the Journal of Clinical Pharmacology, which investigates the effect of Lipitor on the pharmacokinetics of cyclosporine, an immunosuppressant drug. While the study does mention that Lipitor is not significantly metabolized by proteins, it does not provide any information on protein absorption rates.

The third source is a review article published in the Journal of Lipid Research, which discusses the mechanism of action of Lipitor and its effects on cholesterol metabolism. While the article provides a comprehensive overview of Lipitor's effects on cholesterol, it does not mention anything about protein absorption rates.

Therefore, based on the available information, there is no evidence to suggest that Lipitor has any effect on protein absorption rates.
