WebMar 1, 1995 · While toxicokinetic studies were first intended to demonstrate merely that toxicology test animals received drug, they now provide a critical evaluation of drug disposition at toxicologic doses and also the relationships between toxicokinetic values and the occurrence and time course of toxic events. WebJan 21, 2003 · Toxicokinetics is the generation of kinetic data to assess systemic exposure, either as an integral component of preclinical toxicity studies, or in specially designed supportive studies. These data help to understand the relationship between observed toxicity and administered dose.
