Abstract
Pharmaceutical compositions of phthalocyanine compounds with a structure according to Formula (I) are described. Phthalocyanines are photosensitizer compounds having a phthalocyanine ring system that can be used for photodynamic therapy. Different phthalocyanines and phthalocyanine salts are shown to have useful characteristics such as water solubility, oil solubility, or tunable photostability. Formulations of phthalocyanines and phthalocyanine salts that can be used for topical and systemic administration are described.
