guideline: the evaluation of the toxicity data for potential elemental impurities; the establishment of a Permitted Daily Exposure (PDE) for each element of toxicological concern; and application of a risk-based approach to control elemental impurities in drug products.
Sep 24, 2022 · This document presents a process to assess and control elemental impurities in the drug product using the principles of risk management as described in ICH Q9. This process provides a platform for developing a risk-based control strategy to limit elemental impurities in the drug product.
The toxicity of an elemental impurity is related to its extent of exposure (bioavailability). The extent of exposure has been determined for each of the elemental impurities of interest for three routes of administration: oral, parenteral, and inhalational. These limits are based on chronic exposure.
GUIDELINE FOR ELEMENTAL IMPURITIES. Q3D(R2) Draft version . Endorsed on 25 September. Currently under public consultation. This document for public consultation is comprised of extracts of the Q3D(R2) Guideline with the revisions to the Q3D(R1) Guideline: Part 1 - Extract of Appendix 2: Correction of PDEs for Gold, Silver and Nickel.
ICH Q3D(R2): Cutaneous PDEs and error corrections. Table of Contents. Summary of limits for elemental impurities (EI) by the cutaneous and transcutaneous route. Error correction of silver (Ag) PDE by oral route exposure. Error corrections of the gold (Au) PDEs by oral, parenteral and inhalation routes exposure.

elemental impurities in the drug product based on risk assessment and product-specific considerations, unless the drug product must comply with USP–NF requirements (see below).
28 elemental impurities in drug products do not exceed the PDEs. The PDEs established in this 29 guidance are considered to be protective of public health for all patient populations.
The identity of the elemental impurities derived from intentionally added catalysts and reagents is known and strategies for controlling them should be established by using the principles of risk management.
Dec 22, 2018 · The introduction of ICH Q3D (Guideline for Elemental Impurities) 1 was an additional safety-based guidance for toxic impurities that complemented the existing ICH Q3C (R5) (Impurities: Guideline for residual solvents) 2 and ICH M7 (R1) (Assessment and control of DNA reactive (mutagenic) impurities in pharmaceuticals to limit potential carcinogen...
