<qa>  What is the goal of this research proposal?The objective of this research proposal is to conduct a randomized placebo controlled trial of 4 weeks statin therapy in patients in moderate to severe but stable asthma. We hypothesize that statins may directly reduce airway inflammation andor contribute to the anti-inflammatory effects of corticosteroid treatment in these patients. We will measure the effects of statins by measuring airway sensitivity to methacholine, pulmonary function, sputum eosinophils, and quality of life in subjects with asthma after 4 weeks of treatment. Statins may become an alternative treatment option or act as steroid sparing agents in patients with asthma.
