Chronic obstructive pulmonary disease (COPD) is associated with substantial morbidity and mortality and is characterised by persistent airway inflammation, which leads to impaired airway function, quality of life and intermittent exacerbations. In spite of recent advances in the treatment of COPD, new treatment options for COPD are clearly necessary. The oral phosphodiesterase-4 (PDE4) inhibitor roflumilast represents a new class of drugs that has shown efficacy and acceptable tolerability in preclinical and short-term clinical studies in patients with COPD. ⋯ Roflumilast is beneficial for maintenance treatment of patients with severe and symptomatic COPD and with a history of frequent acute exacerbations as an add-on to treatment with long-acting bronchodilators. It may have a role as an alternative to inhaled corticosteroids in more symptomatic COPD patients with frequent exacerbations, although direct comparisons are currently lacking.
