Toxicology (TK) is the branch of pharmacology that describes the behavior and effects of drugs at very high doses in preclinical studies. At these high concentrations, enzymes, transporters, and receptors become saturated, usually resulting in very different behavior and effects of the drug.
Pre-clinical Toxicokinetic (TK) studies have similarities with Pharmacokinetic (PK) studies, but have several key differences. First, toxicokinetic studies are performed at much higher doses which allows for toxic affects to be more apparent. Secondly, TK studies are only conducted in animals rather than humans. Also, the end-point of a TK study is to determine the exposure levels at which toxic effects are observed and results are used to guide dosing recommendations for clinical testing. The objective of a PK study is to enhance drug efficacy by understanding clearance and the bioavailability of the drug within the biological system.
We conduct our high-quality TK assay procedures and results strictly in compliance with GLP regulations and in accordance with international regulatory guidelines (FDA, EMEA, ICH). Measurement are performed using the bioanalytical platforms ELISA or Meso Scale Discovery (MSD).
