WebJan 1, 2024 · Toxicokinetics (and nonlinear pharmacokinetics) The term “toxicokinetics” can take on several different meanings. In the context of drug development, the term is used to describe the concentrations measured in the body during preclinical toxicology studies with the goal of linking systemic concentrations to toxicologic findings. While TK shares important parameters, like Cmax and AUC, with pre-clinical PK, the studies are distinct in several ways: 1. The primary goal of TK is to correlate findings of toxicity (not therapeutic efficacy) with a corresponding level of exposure to an experimental drug compound. 2. TK studies often use doses that … See more In animals, as well as in humans, xenobiotics, or foreign chemical compounds, can undergo drastic changes in location and … See more Over the past decade, advances in microsampling technologies and the development of more sensitive analytical techniques have greatly improved the efficiency of TK … See more In conclusion, TK studies share many common parameters with PK studies, but the purpose of these study types and their relevant dose levels are different.
