Nitrosoamines Impurity
Nitrosoamines, also known as nitrosamines, are a class of organic chemical compounds containing both nitroso and amine groups. Many nitrosoamines are classified as probable or possible human carcinogens. Even low levels of certain nitrosoamines can be potentially harmful.

Origins and Occurrence Nitrosoamines are produced from nitrosation reactions between amines and nitrosating agents like nitrites. They can occur as impurities in certain consumer products made with amines, such as rubbers, tires, adhesives, pesticides, and cosmetics. Nitrosoamines also arise in certain foods and beverages through processing and preservation.

Concerns in Pharmaceuticals In recent years, nitrosoamine impurities have been detected in some drug products containing active pharmaceutical ingredients made with nitrosatable amine precursors. The suspected root causes include changes in manufacturing processes and reagents. Even very low trace nitrosoamine levels raise health concerns due to long-term exposure.

Analytical Testing Methods Advanced analytical techniques like liquid chromatography-mass spectrometry are used to test pharmaceuticals and ingredients for nitrosoamine contamination. Standards have been developed to control acceptable intake for chronic consumer exposure. New testing guidelines improve monitoring for nitrosoamines in drug manufacturing.

Mitigation Strategies Pharmaceutical companies are pursuing various mitigation strategies to prevent nitrosoamine formation, such as using non-nitrosating reagents, adding nitrosoamine inhibitors, optimizing manufacturing conditions, and improving purification processes. Developing robust control methods is an ongoing research priority. Impurityresearch (talk) 04:57, 29 December 2023 (UTC)
