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.
