In the case of amino esters LAs, these are matabolized by plasma estearases and reduce the risk of acute toxicity; however, the opposite is true with regards to their metabolites that are responsible for anaphylactic reactions 5.
En el caso de los AL amino-esteres, estos se metabolizan por esterasas plasmáticas, disminuyendo el riesgo de toxicidad aguda; pero por el contrario, sus metabólitos son responsables de reacciones anafilácticas 5.
