The term asthma chronic obstructive pulmonary disease (COPD) overlap (ACO) has been popularized to describe people who simultaneously have features of both diseases. Analysis of the basis of disease classification and comparison of the clinical, pathophysiological, and therapeutic features of asthma and COPD concludes that it is not useful to use the term ACO. Rather, it is important to make the individual diagnoses, recognizing that both diseases may coexist. If a concurrent diagnosis of COPD is suspected in people with asthma, pharmacotherapy should primarily follow asthma guidelines, but pharmacologic and nonpharmacologic approaches also may be needed for COPD.
