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. Specifically, TK … See more WebJun 12, 2024 · Toxicokinetics (TK) is generation of kinetic data for systemic exposure and toxicity assessment of the drug.

WebMar 1, 1995 · Abstract. Toxicokinetic (TK) studies are the basis for demonstrating dose-related drug exposure in animals and for ensuring that drug exposure is substantially greater in animals than that expected in humans at therapeutic doses. The usefulness of TK studies can be further enhanced by correlating TK parameters with relevant toxicologic end points.
