Double-blind comparison of meglumine lodoxamate (Cholovue) and meglumine iodipamide (Cholografin).

A double-blind comparison of two intravenous cholangiocholecystographic agents of similar molecular structure, meglumine iodoxamate and meglumine iodipamide, was carried out in 90 patients. Each produced a comparably high percentage of satisfactory examinations. A similar pattern of excretion speed and intensity was noted for each, though meglumine iodoxamate appeared to be slightly more effective in patients with elevated serum bilirubin. Less evidence of hepatic toxicity and fewer and less serious adverse side effects were observed in patients given the newer agent, meglumine iodoxamate.
