Chapter2:EtiologyofDrugAllergy

Drugallergycanbetriggeredbyvariousmedications,includingantibiotics,non-steroidalanti-inflammatorydrugs(NSAIDs),andchemotherapeuticagents.Theunderlyingmechanisminvolvestheimmunesystem'sresponsetothedrug,resultingintheproductionofspecificantibodies,suchasimmunoglobulinE(IgE).Thedrugoritsmetabolitesattachtocertainproteinsonimmunecells,givingrisetoacascadeofallergicreactions.Geneticfactorsmayalsocontributetoanindividual'ssusceptibilitytodrugallergens.

Chapter3:ManifestationsofDrugAllergy
