Idiosyncratic drug toxicity

Web1 mei 2024 · The toxicity is attributed to chemical properties of the drug rather than some unique aspect of the drug consumer’s biology. On the other hand, idiosyncratic DILI (IDILI) is often described as non-dose-dependent (i.e. occurs at low doses), unpredictable, and rare (though the definition of “rare” also varies considerably). The proposed mechanism of most idiosyncratic drug reactions is immune-mediated toxicity. To create an immune response, a foreign molecule must be present that antibodies can bind to (i.e. the antigen) and cellular damage must exist. Very often, drugs will not be immunogenic because they are too small … Meer weergeven Idiosyncratic drug reactions, also known as type B reactions, are drug reactions that occur rarely and unpredictably amongst the population.
