WitrynaEvaluation of Stability Data 3 2.2 Data presentation Data for all attributes should be presented in an appropriate format (e.g., tabular, graphical, narrative) and an evaluation of such data should be included in the WitrynaSafety Guidelines. ICH has produced a comprehensive set of safety Guidelines to uncover potential risks like carcinogenicity, genotoxicity and reprotoxicity. A recent breakthrough has been a non-clinical testing strategy for assessing the QT interval prolongation liability: the single most important cause of drug withdrawals in recent …

Impurities and dopants 4.3 Constant concentration of impurity/dopant Schottky equilibria As the predominance of Schottky defect situations have primarily been demonstrated in detail for ionic halides, e.g. alkali halides (NaCl, KBr, LiI a.o.), let us consider the effects of impurities/dopants on Schottky equilibria in a Witryna• Testing for impurities can be either a quantitative test or a limit test for the impurity in a sample. Either test is intended to accurately reflect the purity characteristics of the …
