Abstract
Adverse nocebo responses can cause harm to patients and interfere with treatment adherence and effects in both clinic practice and clinical trials. Nocebo responses refer to negative outcomes to active medical treatments in clinical trials or practice that cannot be explained by the treatment's pharmacologic effects. Negative expectancies and nocebo effects are less known than placebo responses. Nocebo effects can be triggered by verbal suggestions, prior negative experiences, observation of others experiencing negative outcomes, and other contextual and environmental factors. As research advances over the years, mechanistic knowledge is accumulating on the neurobiological mechanisms of nocebo effects. This review summarizes studies on different facets of nocebo effects and responses and discusses clinical implications, ethical considerations, and future directions.
期刊介绍:
Since 1961, the Annual Review of Pharmacology and Toxicology has been a comprehensive resource covering significant developments in pharmacology and toxicology. The journal encompasses various aspects, including receptors, transporters, enzymes, chemical agents, drug development science, and systems like the immune, nervous, gastrointestinal, cardiovascular, endocrine, and pulmonary systems. Special topics are also featured in this annual review.
