Locetamic acid (Cholebrine) and ipodate sodium (Oragrafin) were compared in a double blind study of 503 patients. The radiographs were evaluated for contrast density, visualization of common duct, gallstones, residual in the intestinal tract, and side effects. Cholebrine demonstrated better opacification, fewer repeat examinations, slightly greater common duct opacification, and more frequent visualization of gallstones. Oragrafin had less residue. Side effects were minimal with both contrast agents.
