Mechanism of action

PDE4 inhibition leads to accumulation of cyclic adenosine monophosphate (cAMP) in immune and inflammatory cells, which suppresses the release of pro-inflammatory cytokines and chemokines. This mechanism is intended to reduce inflammation in conditions driven by excessive immune activation, particularly in respiratory and inflammatory diseases.
