Daute is a 56-year-old man seeking evaluation for increasing shortness of breath. He noticed difficulty catching his breath about 3 years ago. Physical activity increases his symptoms. He avoids activity as much as possible to prevent any SOB. His previous physician had placed him on salmeterol/fluticasone (Advair Diskus) one inhalation twice daily 2 years ago. He thinks his physician initiated the medication for the shortness of breath, but he is not entirely sure. He did not refill the prescription and has not been taking it. Pertinent history – Chronic bronchitis X 8 years with one exacerbation in last 12 months of treatment with oral antibiotics. He has a 40-pack-year smoking history. What treatment plan would you implement for this patient? What medication(s) would you prescribe?
