Photostability of epinephrine – the influence of bisulfite and degradation products
Abstract:Sulfites are previously demonstrated to increase the photodegradation of epinephrine. The aim of this study was to clarify the factors responsible for this effect. Adrenochrome sulfonate seems to be the important substance. Photoproduction of singlet oxygen is indicated to be the mechanism by which adrenochrome sulfonate acts. Protection of epinephrine solutions from irradiation <418 nm prevented the photodegradation. A reaction pathway for the photochemical decomposition of epinephrine in the presence of bisulfite is suggested.
