In view of evidence in animals that enterohepatic recirculation of non‐ steroidal anti‐inflammatory drugs contributes to small intestinal mucosal damage we have investigated the extent of biliary elimination of three nonsteroidals. Ibuprofen (n = 3), diclofenac (n = 2) and indomethacin (n = 3) were given to six patients with a percutaneous transhepatic cholangiodrainage placed in the bile duct system. One patient received all three drugs. The mean biliary elimination of ibuprofen was 0.82% of the given dose compared with 50.41% urinary excretion. When diclofenac or indomethacin was administered 4.62% and 6.40% of the dose were found in bile, whereas 34.73% and 32.22% (means) were recovered from urine, respectively. The mean percentage eliminated in bile as unchanged drug and active phase II metabolites was 0.15% for ibuprofen, 1.09% for diclofenac and 5.02% for indomethacin.
