Background and aims-Distension of the proximal stomach is a major stimulus for triggering transient lower oesophageal sphincter (LOS) relaxations. We have shown recently that atropine inhibits triggering of transient LOS relaxations in both normal subjects and patients with gastro-oesophageal reflux disease. Atropine could potentially act centrally by inhibiting the central integrating mechanism in the brain stem, or act peripherally by altering the response of the stomach to distension. The aim of this study was to investigate the eVect of atropine on fasting gastric compliance and postprandial gastric tone using an electronic barostat. (Gut 2000;47:30-36)

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
