Baertschi SW, Clapham D, Foti C, Jansen PJ, Kristensen S, Reed RA, Templeton AC, Tønnesen HH. Implications of In-Use Photostability: Proposed Guidance for Photostability Testing and Labeling to Support the Administration of Photosensitive Pharmaceutical Products, Part 1: Drug Products Administered by Injection. J Pharm Sci. 2013;.
Basic guidance on the photostability testing of pharmaceuticals, designed to cover manufacturing and storage over shelf life, has long been established within ICH Q1(ICH,B(10) , but the guideline does not cover the photostability of drugs during or after administration (i.e., under conditions of use). To date, there has been a paucity of guidance covering the additional testing that would be of value during the clinical preparation and use of products. This commentary suggests a systematic approach, based on realistic "worst case" photoexposure scenarios and the existing ICH Option 1 and 2 light sources, to provide valuable data to pharmaceutical manufacturers and compounding pharmacists for the safe and effective use of photosensitive injection products. © 2013 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci.
