Abstrakt: Background: Determination of the metabolic efficiency of the liver in neoplastic diseases in patients receiving highly toxic drugs is of great practical importance.
Methods: The effect of vinorelbine on the metabolic efficiency of the liver was evaluated by means of phenazone kinetics in rats. The test was compared with a battery of tests routinely used whenever hepatic dysfunction is suspected.
Results: Vinorelbine was administered to the rats and the pharmacokinetic parameters of antipyrine were compared with those in control rats. A statistically significant prolongation of the elimination half-life, as well as a decrease in the elimination constant and clearance of antipyrine were found in the rats receiving the anticancer drug in comparison with controls (p < 0.01). Statistically significant correlations were found between the elimination half-life of antipyrine and serum albumin values (p < 0.01) and prothrombin time (p < 0.001).
Conclusions: Determination of antipyrine pharmacokinetics allows early detection of vinorelbine-induced hepatic dysfunction, with a sensitive scale.
