Lipitor is a medication used to treat high cholesterol levels in the body. After analyzing the provided sources, it is unclear whether Lipitor can impact sodium levels in the body. None of the sources explicitly mention the relationship between Lipitor and sodium levels.

The first source [1] provides information about the patent status of Lipitor and does not mention anything about its effects on sodium levels. The second source [2] is a research article that discusses the potential benefits of statins, including Lipitor, on patients with chronic kidney disease. The study concludes that statins may have beneficial effects on kidney function, but again, there is no mention of the impact on sodium levels.

The third source [3] is a study that investigated the effect of statins on electrolyte and acid-base balance in patients with chronic kidney disease. The study found that statin therapy did not significantly affect serum sodium levels in the body. However, the study had a small sample size, and the authors noted that further research is needed to confirm their findings.

In conclusion, based on the provided sources, it is unclear whether Lipitor can impact sodium levels in the body. While one study [3] suggests that statins do not significantly affect serum sodium levels, further research is needed to confirm this finding. Patients who are concerned about their sodium levels should consult with their healthcare provider.
