Abstract
The effect of metoclopramide on intraluminal pressure of the human gastrointestinal tract was studied by means of tubes and radiopills. Intravenous metoclopramide, 20 mg, stimulates pressure in the stomach, and small and large intestine, but not in the sigmoid and rectum. Metoclopramide induces vigorous antral contractions that are followed by duodenal pressure waves which exhibit a particular phasic activity. During this activity, the radiopill passes rapidly through the small intestine. A reciprocal correlation between pressure and movement of the radiopill was found in the small intestine; no correlation could be detected in the large intestine.
