药物生产过程中在紫外或可见光作用下可能产生有毒的降解产物.接受药物治疗病人的皮肤表皮受到日光照射也会形成光解产物并进而发生有害的光敏效应.不利的光效应通常由UVB(290~310nm)和UVA(310~400nm)的日光直接作用于化合物上引起的,因此多数研究与这些波长光线的照射有关.荧光和磷光
Exposure to ultraviolet light or visible light may produce toxic products of degradation during the course of drug production. Exposure of the patient’s skin epidermis to phototherapeutic drugs also produces photolysis products and thus deleterious photodegradation which is usually caused by UVB (290 ~ 310nm) and UVA (310 ~ 400nm) of the sun directly on the compounds caused, so most of the research and the irradiation of these wavelengths of light related to fluorescence and phosphorescence
