This study is a placebo-controlled, double blind cross-over study of (sildenafil) Revatio® in clinically stable patients with mild to moderate CF lung disease. The length of participation for each subject will be approximately 14 weeks, and will consist of a screening visit, two study visits with initiation of study drug and/or placebo, two interim visits during therapy, two visits at end of each therapy period (to reassess inflammatory markers, pulmonary function, laboratory studies and side effects,) a 28-day washout period with coordinator phone call, and a follow-up assessment 1 week after subject completion.
