Increases image contrast in X-ray studies of the digestive tract. The maximum contrast of the esophagus, stomach and duodenum is achieved immediately after oral administration, the small intestine - after 15 - 90 minutes (depending on the rate of gastric emptying and the viscosity of the drug). The very visualization of the distal small and large intestine depends on body position and hydrostatic pressure.
