DescriptionRoflumilast is a phosphodiesterase-4 (PDE-4) inhibitor. Due to its selective inhibition of the PDE4 isoenzyme in lung cells, roflumilast is indicated for the management of chronic obstrtuctive pulmonary disease (COPD) exacerbations. Treatment with Roflumilast is associated with an increase in psychiatric adverse reactions, including suicide and suicidal attempts.

IndicationRoflumilast is indicated as a treatment to reduce the risk of COPD exacerbations in patients with severe COPD associated with chronic bronchitis and a history of exacerbations. Roflumilast is not a bronchodilator and is not indicated for the relief of acute bronchospasm.
PharmacologyRoflumilast (and its active metabolite, roflumilast N-oxide) increases cyclic adenosine-3′, 5′-monophosphate (cAMP) in lung cells by inhibiting PDE4. Increased cAMP activates PKA, which inactivates transcription factors involved in inflammation. Romflumilast also decreases the amount of sputum neutrophils and eosinophils in COPD patients.
Mechanism of actionRoflumilast is a phosphodiesterase-4 (PDE-4) inhibitor which, due to its selective inhibition of the PDE4 isoenzyme, has potential antiinflammatory and antimodulatory effects in the pulmonary system. It is thought that the increased levels of intracellular cyclic AMP are responsible for the therapeutic actions of Roflumilast.
