title: Phototoxicity of chlorpromazine.
abstract: The constitution of chlorpromazine has been studied in the context of its phototoxicity. Electron transfer from the side chain to the aromatic nucleus of the drug contributes to its instability to light. Even without the side chain, however, chlorophenothiazines appear to be very photolabile, so that it is unlikely that nonphototoxic analogues of chlorpromazine can be prepared merely by altering the constitution of the side chain.
