title: Continuous monitoring of the effect of pentagastrin on gastric emptying of solid food in man.
abstract: By continuous monitoring of a solid meal labelled with a radiopharmaceutical it has been possible to determine the effects of drugs on gastric emptying and motility during a single study. Predictably hyoscine delayed, and bethanechol increased, the rate of gastric emptying. Pentagastrin initially produced marked antral activity resulting in a physiological stricture and subsequent delay in the overall rate of gastric emptying. Fundal motility was unaffected though reflux from the antrum occurred.
