impurities in in drug products recognized that the AIs for certain chemical classes (i.e., aflatoxin-like-, N-nitroso-, and alkyl-azoxy compounds) would likely be significantly lower than the general TTC of 1.5 μg/day considered applicable for mutagenic impurities of all other chemical classes...

By providing guidance on assessing for the presence of nitrosamine, establishing control strategies, and monitoring nitrosamine levels in drug products through ensuring the performance of analytical procedures, the new standard supports both manufacturers and regulators. In 2018, select angiotensin II recepto...
Table I. Acceptable intake limits for some specific nitrosamines in drug products. API and drug product manufacturers should also take a three-step plan to mitigate nitrosamine impurities in their products: Assess the risk of nitrosamine impurities in APIs, marketed products, and products under approv...
products. When bacon is cooked by other methods, particularly in a microwave oven, considerably lower amounts of nitrosamines are found. The majority of evidence suggests that the freeamino acidprolineis first nitrosated and then decarboxylated to form NPYR during frying. Neither the precise ...
Although nitrosamine impurities have been found in only some drug products, and batches of those products have been recalled when there were unacceptable levels of these impurities, nitrosamine impurities might exist in other APIs and drug products due to use of certain processes and materials that ...
Development of nasal drugs: Scientists from our nasal drug development team provide method development, validation, and testing services to help you optimise the performance of your aqueous, powder, and propellant-driven nasal drug products. Conducted in Good Manufacturing Compliant (GMP) laborato......
A challenge FDA faced in this area is how to establish safe levels of exposure to the large number of nitrosamine impurities possibly present at low levels in drug products. Particularly in the case of NDSRIs (those associated with APIs), there is often a lack of substance-specific toxicol...
Unlock the Power to Screen and Characterize Unknown Impurities with Confidence When suspicions arise regarding the presence of new nitrosamines in API or drug products, comprehensive High Resolution Mass Spectrometry (HRMS) screening workflows support robust identification. The ACQUITY Premier,Xevo G3 ...
broad implications of the presence of carcinogenic members of this class ofchemicals, this chapter has been developed to provide a science- and risk-based approach for the control of nitrosamineimpurities to ensure that the potential presence of nitrosamines in drug substances and drug products is ...
