Statins as emerging treatments for asthma and chronic obstructive pulmonary disease

Asthma and chronic obstructive pulmonary disease (COPD) represent increasingly common respiratory conditions with a clear unmet need for more effective and safer therapy. Airway inflammation is key to both asthma pathogenesis and exacerbation of symptoms in COPD. Several lines of evidence are now emerging, demonstrating that, in addition to their established effectiveness in the treatment of atherosclerotic disease, statins also exhibit anti-inflammatory properties, which may be of relevance for the treatment of chronic lung disease, including asthma and COPD. This review will examine the diverse in vitro and in vivo anti-inflammatory properties of statins and consider the available evidence that statins represent novel therapeutic interventions for asthma and COPD.
