Scarring is a consequence of biological tissue repair following trauma. Currently, there are no generally agreed ways to prevent scarring. Recently, kynurenic acid has shown to be a potent modulator of extracellular matrix deposition and remodeling. Kynurenic acid can reduce matrix deposition and other fundamental characteristics of fibrosis in vitro and in vivo. Specifically, kynurenic acid has shown to increase matrix metalloproteinase-1 activity and subsequently reduce collagen deposition in a rabbit ear scar model. In the present study kynurenic acid cream in different concentrations was topically applied on healthy skin on volunteers to assess skin reactions and skin sensitivity in both acute and chronic application settings. Skin reactions were assessed, and concentrations for kynurenic acid were assessed both form serum and urine. Results showed to acute or delayed skin reactions. Kynurenic acid was not detectable in blood at any time point, and only trace elements of kynurenic acid were found in urine. This study supports safety and tolerability of topically administered FS2 when using a liposomal, compounding base carrier. (C) 2018 American Pharmacists Association (R) . Published by Elsevier Inc.
