Pharmacology of inflammatory pain: local alteration in receptors and mediators

摘要

BackgroundInflammation is commonly associated with hyperalgesia. Ideally, this change should abate once inflammation is resolved but this is not necessarily the case because phenotypic changes in the tissue can persist, as appears to be the case in postinfectious irritable bowel syndrome. Basically, all primary afferent neurons supplying the gut can sensitize in response to proinflammatory mediators, and the mechanisms whereby hypersensitivity is initiated and maintained are thus of prime therapeutic interest.
