Aminolevulinic Acid (5-ALA) 20% Solution 20G

5-Amino levulinic acid (5-ALA), is an amino acid noted to be effective in the photosensitization of cells. Over the past decade, 5-ALA has been used in local PDT for the treatment of NMSC (Fang, Tsai, Wu, & Huang, 2008). The mechanism of use of 5-ALA in PDT is based on the intracellular conversion of 5-ALA into protoporphyrin IX, followed by exposure to cause phototoxicity (de Leeuw, van der Beek, Neugebauer, Bjerring, & Neumann, 2009).
