In terms of drug-drug interactions, acetaminophen activates CAR, a nuclear receptor involved in the production of metabolic enzymes, which increases the metabolism of other drugs. This could either cause reactive intermediates/drug activity to persist for longer than necessary, or the drug will be cleared quicker than normal and prevent any ...
A toxicologist working in a lab (United States, 2008)Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms [1] and the practice of diagnosing and treating exposures to toxins and toxicants.
[1] [2] [3] Weight loss drugs have been developed since the early twentieth century, and many have been banned or withdrawn from the market due to adverse effects, including deaths; other drugs proved ineffective. Although many earlier drugs were stimulants such as amphetamines, in the early 2020s, GLP-1 receptor agonists became popular for ...
[1] In regional poison control centers, medical toxicologists provide advice. [1] In medical schools, universities, and clinical training sites, medical toxicologists teach, research, and provide advanced evidence-based patient care. [1] In industry and commerce, medical toxicologists contribute to pharmaceutical research and drug safety. [1]
In toxicology it is specifically the highest tested dose or concentration of a substance (i.e. a drug or chemical) or agent (e.g. radiation), at which no such adverse effect is found in exposed test organisms where higher doses or concentrations resulted in an adverse effect. [3] [4] [5]
A new report breaks down why people stop taking weight loss drugs at the wrong time Here’s what doctors recommend doing if you’re considering stopping.
Pharmacodynamics (PD) is the study of the biochemical and physiologic effects of drugs (especially pharmaceutical drugs). The effects can include those manifested within animals (including humans), microorganisms , or combinations of organisms (for example, infection ).
A well designed toxicokinetic study may involve several different strategies and depends on the scientific question to be answered. Controlled acute and repeated toxicokinetic animal studies are useful to identify a chemical's biological persistence, tissue and whole body half-life, and its potential to bioaccumulate. Toxicokinetic profiles can ...
