Modulation of sensitization processes in the management of pain and the importance of descending pathways. A role for tapentadol?

Objective: This paper presents and discusses recent evidence on the pathophysiological mechanisms of pain. The role of tapentadol-an analgesic molecule characterized by an innovative mechanism of action (i.e., µ-opioid receptor [MOR] agonism and inhibition of noradrenaline [NA] reuptake [NRI])-in the modulation of pain, and the most recent pharmacological evidence on this molecule (e.g., the µ-load concept) are also presented and commented upon. Methods: Narrative review.
