Permitted Daily Exposure List

Here at Affygility Solutions, we often get asked to provide a comprehensive list of all permitted daily exposure (PDE), also known as acceptable daily exposure (ADE), values for active pharmaceutical ingredients (API)s. While I’m sure that there’s someone that could come up with a spreadsheet listing hundreds or thousands of different PDE values, such a listing would lack all scientific credibility and would not pass regulatory authority scrutiny. As indicated in the EMA’s “Guideline on setting health based exposure limits for use in risk identification in the manufacture of different medicinal products in shared facilities” all monographs must “Following an expert review, the company should provide a discussion with respect to the critical endpoints of concern and their rationale for the choice of endpoints and dose that is to be used in the derivation of the PDE.” This means that all monographs must be well documented and include a listing of the scientific references used to determine the permitted daily exposure value.
