Barium Sulfate oral suspension
What is Barium Sulfate oral suspension? BARIUM SULFATE (many brands) is a radiopaque agent used to diagnose problems with the gastrointestinal (GI) tract. When barium is taken by mouth, it makes the upper areas of the GI tract, like the esophagus, the stomach, and/or the small intestine opaque or white so they can be photographed by x-rays. This test is commonly called an 'Upper GI' test. Usually several x-rays are taken to take pictures as the barium moves through the stomach and intestines. The barium procedure shows if anything is wrong inside the GI tract and how well it is working. Generic barium sulfate oral suspensions are available.
