Mechanism of action

Placebo works via psychological and neurobiological mechanisms including expectation, conditioning, and activation of endogenous pain-relief and reward pathways. The effect is not due to the inert substance itself, but rather the patient's belief in treatment and contextual factors surrounding administration. Placebo responses are well-documented across multiple therapeutic areas and can produce measurable physiological changes.
