After reviewing the sources provided, there is no evidence to suggest that Lipitor (atorvastatin) can lower sodium levels. Lipitor is a medication used to lower cholesterol levels by inhibiting the production of cholesterol in the liver [1]. The sources do not indicate any direct effect of Lipitor on sodium levels in the body.

The second source, a study published in the Journal of Pharmacy and Pharmacology, explores the effects of atorvastatin on the liver and kidney functions in rats [2]. The study found that atorvastatin did not have any significant effect on sodium levels in the body.

The third source, an article published in the European Journal of Clinical Pharmacology, discusses the potential side effects of atorvastatin [3]. While the article mentions various side effects, including gastrointestinal issues and muscle pain, it does not mention any effect on sodium levels.

In conclusion, based on the sources provided, there is no evidence to suggest that Lipitor can lower sodium levels. However, it is important to note that if you are taking Lipitor and experiencing any concerning symptoms, you should speak with your healthcare provider.
