These include antiepilepticsantibioticsxrugNSAIDsand general and local anesthetics. Risk factors for drug allergies can be attributed to the drug itself or the characteristics of the patient. Drug-specific risk factors include the dose, route of administration, duration of treatment, repetitive exposure to the drug, and concurrent illnesses. H//o risk factors include age, sex, atopy, specific genetic drg, and inherent predisposition to react to multiple unrelated drugs multiple drug allergy syndrome.
There are drug mechanisms for a drug allergy to occur: IgE or non-IgE mediated. In IgE-mediated reactions, also known as Immunoglobulin E mediated reactions, drug allergens bind to IgE antibodies, which are attached to mast cells and basophils, alllergy in IgE cross-linking, cell activation and release of preformed and newly formed mediators. Most drugs do not cause reactions in themselves, but by the formation of haptens.
