Chapter1:Introduction(Introductiontodigitalisglycosidesanditsclinicalapplications)

Digitalisglycosides,suchasdigoxinanddigitoxin,havebeenwidelyusedinthetreatmentofvariouscardiacdisordersduetotheirpositiveinotropiceffects.Thesemedicationsenhancethecontractilityofthemyocardium,providerelieffromsymptomsofheartfailure,andreducehospitalizations.However,despitetheirtherapeuticbenefits,digitalisglycosidescanelicitallergicreactionsinsomeindividuals.Drug-inducedallergiescanrangefrommildskinirritationstosevereanaphylacticreactions,posingasignificantchallengetohealthcareproviders.Thispaperaimstoexplorethemechanism,clinicalfeatures,andmanagementofdigitalisglycoside-inducedallergicreactions.

Chapter2:Mechanismsofdigitalisglycosideallergies
