Which is a potential source of elemental impurities?
Potential Sources of Elemental Impurities Impurities unintentionally added through the use of impure drug substance, excipients, or reagents in the preparation of the drug product. Contamination or leaching from manufacturing and processing equipment. Leaching from container closure systems.
What is TTC in genotoxic impurity?
The guideline proposes the use of a threshold of toxicological concern (TTC) for genotoxic impurities, an approach already known from the PhRMA task force report. 3 The TTC refers to a threshold exposure level to compounds that do not pose a significant risk for carcinogenicity or other toxic effects.
What is meant by genotoxic impurities?
Per the International Council for Harmonization (ICH) S2 (R1) Guideline, genotoxic impurities can be broadly defined as impurities that have been demonstrated to cause deleterious changes in the genetic material regardless of the mechanism.
What is a mutagenic impurity?
Anything that causes a mutation (a change in the DNA of a cell). DNA changes caused by mutagens may harm cells and cause certain diseases, such as cancer. Examples of mutagens include radioactive substances, x-rays, ultraviolet radiation, and certain chemical3.
What are the elemental impurities?
Elemental impurities are traces of metals that can end up in finished drug products. These impurities can come from multiple points in the manufacturing process, such as residual catalysts from a product’s synthesis or from contact with manufacturing equipment, containers and other materials.

What is the difference between genotoxic and mutagenic?
The genetic change is referred to as a mutation and the agent causing the change as a mutagen. Genotoxicity is similar to mutagenicity except that genotoxic effects are not necessarily always associated with mutations. All mutagens are genotoxic, however, not all genotoxic substances are mutagenic.
What is ICH M7?
The ICH M7 guideline (“Assessment and control of DNA reactive (mutagenic) impurities in pharmaceuticals to limit potential carcinogenic risk”) provides a framework for assessing and controlling DNA reactive impurities in a pharmaceutical product (ICH M7, 2015a). Definition of the ICH M7 hazard classifications.

What is elemental impurity?
What are the different types of impurities?
The three different types of impurities in pharmaceuticals include organic, inorganic, and residual solvents. Most of these impurities occur due to manufacturing processes, degradation, storage conditions, excipients, or contamination.
Is Iron an elemental impurity?
Class 4 elemental impurities include Boron (B), Iron (Fe), Zinc (Zn), Potassium (K), Calcium (Ca), Sodium (Na), Manganese (Mn), Magnesium (Mg), Tungsten (W), and Aluminum (Al).
