PK and TK Study
Pharmacokinetics studies the dynamic changes of drug metabolism in the body, including adsorption, distribution, metabolism and excretion (ADME). The toxicokinetics which is based on the principles and methods of pharmacokinetics, is to quantitatively study ADME and characteristics of drugs in animals at toxic doses. TK helps to know the distribution and target organ of drug in animals, and supplies basis for other toxicity tests and results evaluation. Our center has radiation safety license and class C unsealed radioactive material workplace, and PK and TK study of radioisotope labeled drug could be carried out.
