title: [Photochemistry of pharmaceutical substances].
abstract: The chemistry of excited states is now well understood, and the photo-instability of pharmaceutically active molecules can be rationalized or predicted. Some relevant examples are discussed and include both reactions of the excited state of the substrate and reactions caused by active species photochemically generated from other components, as well as the effect of the physical state of the sample on the reaction.
