WebJun 28, 2024 · TK studies are typically performed with unlabeled (no radioactivity) chemical/substance. Data from the ADME studies are generally used to determine the analytes to be monitored in TK studies using validated analytical methods such as gas chromatography- and liquid-chromatography-mass spectrometry. WebMar 31, 2024 · Toxicokinetics (TK) is the application of the pharmacokinetics (PK) assessment of parent compound and/or metabolite (s) in animals. Therefore, understanding the PK processes is essential for the TK assessment. Pharmacokinetics is derived from ancient Greek “pharmakon” means “drug” and “kinetikos,” means “position in motion.”
