Multicenter Study Comparative StudyCapsaicin cough sensitivity in smokers with and without airflow obstruction.
Cough is a frequent symptom of cigarette smokers that often precedes the development of airflow obstruction. We determined whether chronic cigarette smoking is associated with an increase in capsaicin cough response in the absence of cough. ⋯ We conclude that chronic cigarette smoking increases capsaicin cough reflex and that this remains so with the development of COPD.
