Roflumilast (trade names Daxas, Daliresp) is a drug which acts as a selective, long-acting inhibitor of the enzyme PDE-4. It has antiinflammatory effects and is under development as an orally administered drug for the treatment of inflammatory conditions of the lungs such as asthma, and chronic obstructive pulmonary disease (COPD).^[1][2][3][4] While roflumilast was found to be effective in clinical trials, it produced several dose-limiting side effects including nausea, diarrhoea and headache, and development is continuing in an attempt to minimise the incidence of side effects while retaining clinical efficacy.^[5]

In June 2010, Daxas was approved in the EU for severe COPD associated with chronic bronchitis.^[6] In March 2011, Daliresp gained FDA approval in the US for reducing COPD exacerbations.^[7]
