[Pharmaco-kinetic investigations of a new gall bladder contrast medium--iodoxaminic acid (author's transl)].

Pharmaco-kinetic studies of the cholecystographic contrast medium iodoxaminic acid (Diglumin-Iodaxamate) which is characterised by low toxicity, revealed a half-value period of 93 minutes in the serum and a urinary excretion rate of 12.5% in 24 hours. This indicated the probability that this medium would be suitable for the radiological demonstration of the biliary tract when compared with known and tried contrast media.
