  • Mechanism of Action Diagram - PDE4
  • Mechanism of Action Diagram - Otezla

PDE4 has been shown to be present within inflammatory cells2-5

Inflammatory cella

The interior of an inflammatory cell showing how phosphodiesterase 4 (PDE4) breaks down cyclic AMP into AMP

The role of phosphodiesterase 4 (PDE4) and cyclic adenosine monophosphate (cAMP) in controlling inflammation

  • cAMP is a second messenger for a variety of inflammatory mediators4
  • PDE4 is a cAMP-specific PDE that has been shown to degrade cAMP to AMP in inflammatory cells3-5
  • The balance between cAMP and AMP within a cell may modulate the expression of pro-inflammatory and anti-inflammatory mediators2

Otezla is a non-biologic PDE4 inhibitor that works intracellularly1-3

Inflammatory cella

The mechanism of action of Otezla

  • The specific mechanism(s) by which Otezla® (apremilast) exerts its therapeutic action in patients with BD is not well defined3
  • By elevating cAMP levels, Otezla is thought to indirectly modulate production of inflammatory mediators1,2
