The use of statins and lung function in current and former smokers.

Background: Smokers are affected by a variety of inflammatory diseases, including COPD. Statins, 3-hydroxy-3-methyl-glutaryl-coenzyme-A reductase inhibitors, are used for their lipid-lowering characteristics but also appear to have antiinflammatory and immunomodulatory activities. We assessed their ability to preserve lung function in current and former smokers.
