In 2012, The Danish Society of Respiratory Medicine gave birth to their most recent guideline regarding chronic obstructive pulmonary disease (COPD). Much has happened since, and in late 2017 an update has been published. Chapters have been deleted, and new ones added. The major alteration has been in the section concerning treatment with inhalation medication – now aiming at an easy stepwise up-titration of long-acting medicine as well as a guide of how to down-titrate inhaled corticosteroids. This article mainly focuses on how to treat stable COPD according to The Danish Society of Respiratory Medicine.
