Can light absorption and photostability data be used to assess the photosafety risks in patients for a new drug molecule?

The current study was undertaken to determine the level of light absorption by measuring the molar extinction coefficients (MEC) of a wide range of compounds reported in the literature to have known photosafety issues in humans and the results have shown that all compounds tested have absorbance intensities significantly above an MEC threshold of 1000 L mol (-1)cm(-1) and also display a widerange of photoinstability.
