Phosphodiesterase-4 Inhibitors

Selective phosphodiesterase-4 (PDE-4) inhibitors reduce exacerbations, improve dyspnea, and increase lung function in patients with severe COPD.

Roflumilast (Daliresp)

Roflumilast is a selective phosphodiesterase-4 (PDE-4) inhibitor. The specific mechanism of action is not well defined but is thought to be related to the effects of increased intracellular cyclic AMP in lung cells. It is indicated to decrease the frequency of exacerbations or the worsening of symptoms from severe COPD.
