The drug Lipitor, also known as atorvastatin, is primarily used to lower cholesterol levels in the blood. There is no direct evidence or indication from the provided sources that Lipitor can enhance range of motion in arthritis patients. Arthritis is a condition characterized by joint inflammation, and while some studies have suggested a potential link between cholesterol-lowering statin medications like Lipitor and reduced inflammation in arthritis, the evidence is not conclusive. It is essential for arthritis patients to consult with their healthcare providers to determine the most appropriate treatment options for managing their condition.
