[Studies on the biliary excretion of the hepatotropic contrast media ioglycamate and iotroxinate in pigs and men (author's transl)].

The distribution and biliary excretion of two hepatotropic contrast media, Ioglycamate and Iotroxinate, has been studied in the anaesthetized pig in infusion experiments. The new substance Iotroxinate exceeds the Ioglycamate in two of the investigated parameters: it was excreted faster and reached a higher biliary concentration. The biliary transport maximum, however, was unchanged. On the basis of these experiments the new contrast medium Iotroxinate was tested in men.
