Chronic obstructive pulmonary disease (COPD) is a chronic disorder with high mortality rates (one of the top 5 causes of death).

COPD is expected to rise to the third leading cause of death worldwide by 2030. More than 25% of COPD patients have never been smokers.

Some important controversies in COPD management still exist:

- The classic way to define COPD has been based on spirometric criteria, but more relevant diagnostic methods are needed that can be used to describe COPD severity and comorbidity

- Initiation of interventions earlier in the natural history of the disease to slow disease progression is debatable

- There are controversies about the role of inhaled corticosteroids (ICS) in the management of COPD

- Long-term antibiotics for prevention of exacerbation have had a resurgence in interest

New drugs are urgently needed for management of COPD exacerbation.

COPD is a complex disease and consists of several phenotypes that in future would guide its management.
