title: Effect of bilirubin on the distribution, elimination and anticoagulant action of dicumarol in Gunn rats-1-2 (38547).
abstract: Jaundiced Gunn rats were found to have a significantly larger apparent volume of distribution and higher rate constant for elimination of dicumarol than their nonjaundiced littermates.  Anticoagulant effect-log plasma dicumarol concentration lines were parallel in the two groups of animals, with the line for the jaundiced rats shifted to a lower concentration range.  In vitro studies showed that bilirubin can displace dicumarol from serum protein binding sites. There are indications of a genetic influence on the distribution and anticoagulant effect of dicumarol in Gunn rats.
