Mechanism of action

Placebo is a pharmacologically inactive substance administered alongside active medications or as a standalone intervention. Any therapeutic benefit derives from the placebo effect—a psychobiological response involving patient expectation, conditioning, and the therapeutic context rather than direct drug action. Placebo add-on formulations are typically used in research protocols or clinical practice to enhance perceived efficacy through psychological mechanisms.
