Nakayama, Shintaro published the artcileA zone classification system for risk assessment of idiosyncratic drug toxicity using daily dose and covalent binding, Recommanded Product: 2-(2,3-Dichloro-4-(thiophene-2-carbonyl)phenoxy)acetic acid, the main research area is idiosyncratic drug toxicity daily dose covalent binding risk assessment.

The risk of idiosyncratic drug toxicity (IDT) is of great concern to the pharmaceutical industry. Current hypotheses based on retrospective studies suggest that the occurrence of IDT is related to covalent binding and daily dose. The authors determined the covalent binding of 42 radiolabeled drugs in three test systems (human liver microsomes and hepatocytes in vitro and rat liver in vivo) to assess the risk of IDT. On the basis of safety profiles given in official documentation, tested drugs were classified into the safety categories of safe, warning, black box warning, and withdrawn. The covalent binding in each of the three test systems did not distinguish the safety categories clearly. However, when the log-normalized covalent binding was plotted against the log-normalized daily dose, the distribution of the plot in the safety categories became clear. An ordinal logistic regression anal. indicated that both covalent binding and daily dose were significantly correlated with safety category and that covalent binding in hepatocytes was the best predictor among the three systems. When two separation lines were drawn on the correlation graph between covalent binding in human hepatocytes and daily dose by a regression anal. to create three zones, 30 of 37 tested drugs were located in zones corresponding to their resp. classified safety categories. In conclusion, the authors established a zone classification system using covalent binding in human hepatocytes and daily dose for the risk assessment of IDTs.
