Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the body. While there is no direct evidence that Lipitor affects range of motion, it is known that high cholesterol levels can lead to inflammation in the body, which can cause joint pain and stiffness [2]. By lowering cholesterol levels, Lipitor may help reduce inflammation in the body and alleviate joint pain and stiffness, which could potentially improve range of motion.

In addition, a study published in the Journal of Neuroinflammation found that atorvastatin can reduce inflammation in the brain and spinal cord [3]. Inflammation in these areas can cause damage to nerve cells and lead to neurological disorders, including those that affect movement and range of motion. By reducing inflammation in these areas, atorvastatin may help improve neurological function and range of motion.

It is important to note that the exact mechanism behind Lipitor's potential effects on range of motion is not fully understood and more research is needed to fully explore this potential benefit. Additionally, it is important to talk to a healthcare provider before starting or stopping any medication, as Lipitor may have potential side effects and interactions with other medications [1].
