This study will determine if atorvastatin (Lipitor) can help patients with pulmonary (lung) sarcoidosis and replace or reduce the need for patients to take steroids, such as prednisone. Sarcoidosis is an inflammatory disease that can affect nearly any part of the body. Pulmonary sarcoidosis may resolve on its own or it may progress to irreversible lung damage, disability, and death. Many sarcoidosis patients are treated with prednisone, but the drug is not effective in all patients, and it can cause serious side effects, such as high blood pressure, sugar diabetes, eye cataracts, and bone thinning.
