Preparado de lisina y aspirina con acciones antiinflamatorias, antipiréticas y analgésicas similares a las de la aspirina.
Una vez administrado se disocia en el aminoácido lisina y en aspirina. 900 mg de Acetilsalicilato de lisina equivalen a 500 mg de Aspirina.

El argumentario sobre la compatibilidad durante la lactancia es el mismo que el de la Aspirina.
