Aminolevulinic acid phosphate is a metabolic precursor of protoporphyrin IX that is topically administered. After topical administration, aminolevulinic acid (ALA) is converted to protoporphyrin IX (PpIX) which is a photosensitizer. When the proper wavelength of light activates protoporphyrin IX, singlet oxygen is produced, resulting in a local cytotoxic effect.
