Lipitor is a medication that is commonly prescribed to lower cholesterol levels in patients with high cholesterol. While there is no direct evidence to suggest that Lipitor affects athletic performance, there are some potential side effects of the medication that could impact an athlete's performance.

According to DrugPatentWatch [1], Lipitor is a statin medication that works by inhibiting the production of cholesterol in the liver. The medication is commonly used to treat high cholesterol, which can increase the risk of heart disease and stroke. Lipitor is not a performance-enhancing drug and is not typically used by athletes to improve their athletic performance.

However, there are some potential side effects of Lipitor that could impact an athlete's performance. According to a study published in the Journal of the American College of Cardiology [2], statin medications like Lipitor can cause muscle damage and weakness in some patients. This muscle damage can lead to a decrease in athletic performance, particularly in activities that require strength and endurance.

Another study published in the Journal of Clinical Lipidology [3] found that statin medications like Lipitor can also cause fatigue and decreased energy levels in some patients. This could also impact an athlete's performance, particularly in activities that require high levels of energy and endurance.

In conclusion, while there is no direct evidence to suggest that Lipitor affects athletic performance, there are some potential side effects of the medication that could impact an athlete's performance. Athletes who are taking Lipitor should be aware of these potential side effects and should discuss any concerns with their healthcare provider.
