Nitrosamine contamination of pharmaceuticals: Cases in Japan, formation mechanisms, detection methods, regulatory perspectives, and insights

Journal of Pharmaceutical and Biomedical Analysis Open
In recent years, mutagenic nitrosamines, such as N-nitrosodimethylamine, have been detected in medicine. This has led to global product recalls and long-term supply suspensions by pharmaceutical companies and consequent clinical impacts.
