In Nitrosamine Testing, Our Quality Protects Yours
Nitrosamines in Pharmaceuticals
The pharmaceutical industry heightened its concern about nitrosamines, particularly N-nitrosodimethylamine (NDMA), after its discovery in valsartan in July 2018. This triggered recall of angiotensin II receptor blocker medications, leading to increased scrutiny for nitrosamine impurities in drug products. Multiple factors, including degradation processes, contaminated raw materials, solvents, and reagents, contribute to the presence of these "unintended" organic impurities in pharmaceuticals.
Classified as Class 1 impurities, these N-nitrosamines are designated as "cohort of concern" compounds and "known mutagenic carcinogens" by the ICH Guideline M7(R1). Additionally, they are classified as 2A–Probable Carcinogens by the International Agency for Cancer Research (IARC), highlighting the critical need for rigorous nitrosamines analysis in the pharmaceutical industry. The FDA’s list of nitrosamine impurities, including NDMA, NDEA (N-nitrosodiethylamine), NIEPA, NDIPA, NDBA (N-nitrosodibutylamine), and NMBA, highlights NDMA and NDEA as the most prevalent nitrosamines in drugs. Current regulatory restrictions allow only very low levels, requiring highly sensitive analytical techniques for nitrosamine detection.
We offer a comprehensive portfolio of nitrosamine testing products, supported by detailed application guidelines, ensuring reliable detection of these carcinogenic nitrosamines using LC-MS or GC-MS methodologies.
