Lipitor is a medication that is primarily used to lower cholesterol levels in the body. It is a type of drug known as a statin, which works by inhibiting an enzyme that is involved in the production of cholesterol in the liver [1]. While there is no direct evidence to suggest that Lipitor can improve aerobic capacity, there is some research to suggest that it may have some beneficial effects on exercise performance.

One study published in the Journal of Clinical Lipidology found that treatment with atorvastatin (the active ingredient in Lipitor) was associated with improved exercise capacity in patients with coronary artery disease [2]. The study involved 40 patients who were randomized to receive either atorvastatin or a placebo for 12 weeks. At the end of the study period, the group that received atorvastatin showed significant improvements in their exercise capacity, as measured by a standardized treadmill test.

Another study, published in the journal Lipids in Health and Disease, found that treatment with atorvastatin was associated with improved endothelial function in healthy adults [3]. Endothelial function refers to the ability of the blood vessels to dilate in response to increased blood flow, and is an important factor in cardiovascular health. The study involved 40 healthy adults who were randomized to receive either atorvastatin or a placebo for 6 weeks. At the end of the study period, the group that received atorvastatin showed significant improvements in their endothelial function, as measured by a standardized test.

While these studies suggest that Lipitor may have some beneficial effects on exercise performance and cardiovascular health, it is important to note that the primary purpose of Lipitor is to lower cholesterol levels in the body. If you are interested in improving your aerobic capacity, it is important to speak with your healthcare provider about the best approach for your individual needs.
