  • Title: [Comparison of the biliary excretion of the radiographic contrast media Iotroxamate and Ioglycamide in the dog].
    Author: Grandjean EM, Zaunbauer W, Paumgartner G, Fuchs WA.
    Journal: Schweiz Med Wochenschr; 1978 Jul 15; 108(28):1073-5. PubMed ID: 675198.
    Abstract:
    Biliary excretion of iotroxamat (ITX) and ioglycamide (IGL) in cholecystectomized dogs fitted with a Thomas duodenal cannula is compatible with saturation kinetics exhibiting maximal excretory velocities of 2.23 +/- SD 0.18 and 1.22 +/- 0.19 mumol/min/kg, respectively. While biliary excretion of ITX obeyed classical Michaelis Menten kinetics, the data obtained with IGL suggested a more complex process. The choleretic effects of both contrast agents (23.6 +/- SD 2.29 and 25.8 +/- 2.21 microliter of excreted substance) were comparable. On the basis of these results and in view of the similar toxicity of the two contrast agents in animals, it may be expected that ITX will have advantages over IGL for intravenous cholangiography.
