WitrynaThere are three parts of this 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. Witryna2 drug development stages, impurity standards are often not available, and the identity of peaks cannot easily be determined. Genotoxic impurities are a special group of impurities that pose a greater risk to patient health, since they are carcinogenic.1 The genotoxic impurities identified as potential contaminants of the drug must be monitored
