Review Question - QID 210984

A 52-year-old man presents to his primary care physician because he has been experiencing shortness of breath and cough. He began feeling short of breath when playing recreational soccer with his friends. Over time these episodes have become more severe. They now impair his ability to work as a construction worker. In addition, he has developed a chronic dry cough that has been increasing in intensity. Radiography reveals subpleural cystic enlargement, and biopsy reveals fibroblast proliferation in the affected tissues. Which of the following describes the mechanism of action for a drug that can cause a similar pattern of pulmonary function testing as would be seen in this disease?
