Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels in the blood. According to Drug Patent Watch [1], Lipitor was first approved by the FDA in 1996 and has been used by millions of people worldwide.

There is limited research on the effects of Lipitor on athletic performance. However, a study published in the Journal of Clinical Lipidology [3] found that high-intensity exercise performance was not significantly affected by atorvastatin treatment. The study concluded that atorvastatin did not impair exercise performance in healthy, physically active individuals.

Another study published in the Journal of the American College of Cardiology [2] found that atorvastatin did not negatively impact muscle strength or exercise performance in patients with heart disease. The study suggested that atorvastatin may even improve muscle function in patients with heart disease.

In summary, the available research suggests that Lipitor (atorvastatin) does not negatively impact athletic performance in healthy individuals or those with heart disease. However, it is important to consult with a healthcare provider before starting any new medication, as individual responses to medications may vary.
