Application

Roflumilast has been used to evaluate its effect on acute lung inflammation and chronic lung changes in models of cigarette exposure in mice. It is also used to investigate its therapeutic potential to ameliorate primary blast-induced deficits in long-term potentiation (LTP).

Biochem/physiol Actions

Roflumilast is a highly potent, orally active, and selective phosphodiesterase 4 (PDE4) inhibitor with an IC50 of 0.8 nM. Roflumilast has anti-inflammatory properties and is used clinically to treat COPD.

Roflumilast is an oral, selective phosphodiesterase 4 inhibitor with anti-inflammatory effects in chronic obstructive pulmonary disease (COPD). The addition of roflumilast to long-acting bronchodilators improves lung function in patients with moderate-to-severe COPD. The present study investigated drug-drug interaction effects between
