WHAT IS A DRUG INJURY?

A DRUG INJURY
HLA associations reported with serious ADRs caused by many different drugs. This is not an exhaustive list of reported drug-HLA associations but illustrates that the pattern of drug–HLA–tissue injury interactions varies and that there is no general rule for predicting susceptibility. New genetic findings lead the way to a better understanding of fundamental mechanisms of drug hypersensitivity.
