Brief Summary
Specific Aim: To determine the effectiveness of Roflumilast in improving i) whole right lung and ii) peripheral right lung mucociliary clearance (MCC) in patients with COPD and chronic bronchitis. Hypothesis: Roflumilast increases mucociliary clearance in patients with chronic bronchitis. Study Design: This will be a double-blinded, cross-over randomized controlled trial with 1:1 randomization of 20 individuals with chronic bronchitis. Subjects will undergo baseline MCC then will be randomized to either roflumilast or placebo x 4 weeks, then there will be a 4 week wash-out phase and a second 4 week period of roflumilast/placebo depending on initial randomization. MCC will be conducted at baseline and at the end of each 4 week medication phase.

Outcome Measures
Primary Outcomes (4)
Difference in Mucociliary Clearance (MCC) Between Visit 1A and Visit 2A
Measurements of MCC (Mucociliary clearance) will be obtained using a large-field-of-view 2D gamma camera (Siemens Orbiter) following inhalation of a radioaerosol containing a gamma emitting isotope 99mtechnetium (99mTc)-sulfur-colloid. The total exposure to radiation from procedures associated with the MCC studies is similar to that of a chest x-ray and is much less than the 0.3 rem that the average person in the United States gets each year from natural sources like the sun, outer space, air, food, and soil. After inhaling (0 time point) an aerosol generated from a saline solution containing the radioisotope 99mtechnetium (99mTc)-sulfur-colloid (radioaerosol), subjects will sit with their back to a gamma camera. The gamma camera will acquire an image of where the isotopic marker initially deposits in the right lung at time 0 and how much remains in the lungs at the specified time point and will be measured in change of %/min from 0 min time point.
