NCT01247870

Brief Summary

The purpose of this study is to determine the effect of a tablet medication, called metformin, in flare-ups (exacerbations) of chronic obstructive pulmonary disease. The investigators believe that metformin may effectively control the blood sugar level during COPD exacerbations. This is important because there is evidence that a high blood sugar level during exacerbations may be linked with a worse prognosis. The investigators also think that metformin may have other potentially useful effects on inflammation, antioxidant levels, the effectiveness of steroid treatment, and recovery.
