Patients, who are 18-70 years old, with stage II or III pulmonary sarcoidosis, diagnosed by a compatible clinical history and supported by a lung, lymph node, or tissue biopsy, will be enrolled in the study, if they require prednisone therapy. The patients will be randomly assigned to two groups; as prednisone is tapered, one group will receive placebo and the other, atorvastatin. The two study drugs will be administered for twelve months, during which time patients will be periodically evaluated as to their clinical status and prednisone requirements. Pill counts and patient diaries will be used to determine the amount of steroid use during the study period. Patients with pulmonary fibrosis greater than 50 percent of total lung volume or severe co-morbidities will be excluded from the trial.
