drug hypersensitivity is an adverse reaction provoked by an immunologic response due to the consumption of a drug, or else, by reaction to one of their metaboliteS. Currently, it is considered that 10% of general population has susceptibility to a drug hypersensitivity to a drug or biological product. These reactions obey a pattern of factors of the individual and the medicine, that define the degree of sensitivity to the drug, and according to their characteristics it is possible to develop any type of immunologic reaction (Gel & Coombs), Nevertheless, it should be established that still there are mechanisms of drug hypersensitivity of drugs that have not been totally known, so they are not integrated to this classification and they are catalogued as an undefined type of reaction. On the other hand, there are drugs that provoke drugs reactions by non-immunologic mechanisms corresponding to the drug's different aggressive effects. According to the indicated concepts, we will show some basic concepts of the diverse mechanisms of drug hypersensitivity immunologic and non-immunological, thus as some therapeutic and diagnostic concepts needed for the management of drug hypersensitivity.
