Considerations when deriving compound-specific limits for extractables and leachables from pharmaceutical products: Four case studies.

Considerations when deriving compound-specific limits for extractables and leachables from pharmaceutical products: Four case studies. Regul Toxicol Pharmacol. 2020 Oct 07;:104802 Authors: Parris P, Martin EA, Stanard B, Glowienke S, Dolan DG, Li K, Binazon O, Giddings A, Whelan G, Masuda-Herrera M, Bercu J, Broschard T, Bruen U, Callis CM, Stults CLM, Erexson GL, Cruz MT, Nagao LM Abstract Leachables from pharmaceutical container closure systems are a subset of impurities that present in drug products and may pose a risk to patients or compromise product quality. Extractable studies can identify potential leachables, and extractables and leachables (E&Ls) should be evaluated during development of the impurity control strategy. Currently, there is a lack of specific regulatory guidance on how to risk assess E&Ls; this may lead to inconsistency across the industry. This manuscript is a cross-industry Extractables and Leachables Safety Information Exchange (ELSIE) consortium collaboration and follow-up to Broschard et al. (2016), which aims to provide further clarity and detail on the conduct of E&L risk assessments. Where sufficient data are available, a health-based exposure limit termed Permitted Daily Exposure (PDE) may be calculated and to exemplify this, case studies of four common E&Ls are described herein, namely bisphenol-A, butylated hydroxytoluene, Irgafos® 168, and Irganox® 1010.
