Abstract

This manuscript presents the basic concepts of Photodynamic Therapy (PDT), describing and analyzing the components and stages of the photodynamic action and potential of therapeutic efficacy. It is discussed the choice of photosensitizers (PS) and the source of electromagnetic energy as well as the mechanisms TYPE I and TYPE II of the photodynamic action generated by the electronic excitation of the photosensitizer agent. Therefore, it is analyzed the chemical aspects of the oxidative stress generated by the reactive oxygen species (ROS) and reactive nitrogen species (RNS), including singlet oxygen (1O2) and free radicals. Finally, it is commented upon the possibilities of higher application of PDT in veterinary medicine, mainly with respect to the pet animals.
