Ddt toxicokinetics
WebToxicodynamics is the toxicological counterpart of pharmacodynamics, which refers to the effects that a chemical has on an organism following a defined exposure. 8 In pharmacology, pharmacodynamics is sometimes confined to beneficial or therapeutic effects. Likewise in toxicology, toxicodynamics refers to adverse or injurious effects. 9 Toxicodynamics can be used in combination with toxicokinetics in environmental risk assessment to determine the potential effects of releasing a toxicant into the environment. The most widely used method of incorporating this are TKTD models. Both toxicokinetics and toxicodynamics have now been described, and using these definitions models were formed, where the internal concentration (TK) and damage (TD) are simulated in re…

They are bioactivated to reactive intermediates which bind covalently to the adrenal cortex causing cell death. Due to its tissue specific toxicity o,p’-DDD has been used as a chemotherapy drug for adrenal cancer in humans.
WebApr 28, 2024 · Toxicokinetics (TK) is defined as the generation of pharmacokinetic (PK) data, either as an integral component in the conduct of nonclinical toxicity studies or in specifically designed supportive studies to assess systemic exposure. TK describes the use of bioanalytical sampling to characterize the disposition of a target compound during time ... WebToxicokinetics is the study of kinetics of absorption, distribution, metabolism, and excretion of a xenobiotic under the conditions of toxicity evaluation. Conventional toxicokinetics uses the hypothetical compartments, and the model is composed of rate equations that describe the time course of drug and chemical disposition.
