Mechanism of action

PDE4 inhibition leads to accumulation of cyclic adenosine monophosphate (cAMP) in immune and inflammatory cells, suppressing the release of pro-inflammatory cytokines and chemokines. This mechanism reduces airway inflammation and mucus production, making it potentially useful in chronic inflammatory airway diseases. The selective PDE4 inhibition aims to provide anti-inflammatory benefits while minimizing systemic side effects associated with non-selective phosphodiesterase inhibition.
