Gene Information

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 the first phosphodiesterase-4 (PDE4) inhibitor to have been approved for the treatment of COPD. The anti-inflammatory profile of PDE4 inhibitors has not yet been explored in human lung tissues. We investigated the effects of roflumilast and its active

The principal active component of isoforskolin (ISOF) is from the plant Coleus forskohlii, native to China, which has attracted much attention for its biological effects. We hypothesize that ISOF and forskolin (FSK) pretreatment attenuates inflammation induced by lipopolysaccharide (LPS) related

Roflumilast reduces exacerbations in patients with severe chronic obstructive pulmonary disease. Its effect in patients using fixed combinations of inhaled corticosteroids and longacting β2 agonists is unknown. We postulated that roflumilast would reduce exacerbations in patients with severe chronic obstructive
