Topical PDT Photosensitizers (5-ALA and MAL) Therapeutic Cheat Sheet
5-aminolevulinic acid (5-ALA) is an FDA-approved prodrug used in combination with light therapy for treatment of actinic keratosis and superficial basal cell carcinoma. It is a naturally occurring amino acid that is an intermediate of the heme biosynthesis pathway which cells convert into the photosensitizing metabolite protoporphyrin IX (PpIX). This compound has been applicable in two specific cl …

The incidence for non-melanoma skin …
Your patient with extensive actinic damage and many of the lesions seen here is interested in field therapy with a light-based modality. On a cellular level, how does photodynamic therapy kill cells that make up this lesion?
A. Heat shock proteins
B. Inhibition of pyrimidine nucleotide synthesis
C. Neutrophil-mediated, antibody-dependent cellular cytotoxicity
D. Reactive singlet ox …
