Abstract | INTRODUCTION: AREAS COVERED: The preclinical, clinical and post-marketing development of roflumilast is described. Furthermore, a critical analysis of the clinical data and positioning of this drug is undertaken in this review Expert opinion: The identification of a subset of COPD patients, namely those suffering from severe airflow obstruction with symptoms of chronic cough and sputum and a history of previous exacerbations, as a specific target for roflumilast with the goal of reducing exacerbations, was entirely casual because the delineation of a ' chronic bronchitis' responder group was clearly a post-hoc finding. However, it was useful to design prospective clinical trials that demonstrated reduced exacerbations in this specific subset of patients towards whom roflumilast therapy is now targeted. In any case, these pivotal trials still do not provide more accurate identification of the type of exacerbation to be treated by roflumilast. The identification of the right biological COPD exacerbation phenotype and/or the right clinical COPD phenotype are the only means that could justify the use of roflumilast as a first line anti-inflammatory therapeutic approach.
