Nitrosamines are back in the news following the mass recall of a popular US heartburn medication, prompting the US Food and Drug Administration to call in various drugs known as ARBs for testing, and suppliers like Novatis and Sanofi to cease distribution.
In Europe, the European Medicines Agency (EMA) has requested that Marketing Authorization Holders of all Finished Pharmaceutical Products (FPPs) conduct a risk assessment to determine the potential for nitrosamine content. This is particularly relevant for the nitrosamines NDMA and NDEA that belong to the WHO ‘cohort of concern,’ classified as ‘probable human carcinogens.’
The 800 Series TEA interfaced with Ellutia’s proprietary chemical stripping system is a unique instrument on the market that offers total nitrosamine analysis of pharmaceutical products. The system allows rapid and accurate quantification of the total nitrosamine content of a sample.
Measuring apparent total nitrosamine content (ATNC) provides a benchmark of the nitrosamine volume in a product. Rather than embark on a lengthy analytical process to deliver detailed and speciated results in the first instance, the ATNC method screens only for the total nitrosamine content (this includes both volatile and non-volatile nitrosamines) and returns an analysis with a single clear peak. This peak either falls within or outside the interim allowable daily intake set by the World Health Organization (WHO) for specific species of nitrosamines. If the peak of the total sample falls within the daily intake allowance, then no single nitrosamine can possibly be above the value and the nitrosamine content is reported as safe.
In contrast, any sample found to contain an ATNC outside the safe level can be red flagged and sent for further analysis by a TEA interfaced with a GC or HPLC to individually identify the species and quantify the presence of nitrosamines such as NDMA.
Ellutia’s 800 series TEA and chemical stripping system offers rapid time to results for ATNC, with a typical single-peak analysis taking just between one and ten minutes.
Andrew James, marketing director at Ellutia, said: “The risk assessment requirement from the European medicines agency means that pharmaceutical manufacturers need to take a serious look at potential nitrosamine contamination in their product lines. By adopting the ATNC quantification method in the first instance, any sample that results in a safe analysis can be passed immediately. Any sample found to contain levels outside the safe value can be sent for further analysis with the TEA system.”
Ellutia will also hold live demonstrations of its 500 Series GC (gas chromatograph) on stand at Pittcon, offering conventional, fast and ultrafast chromatography in a single system, freeing up valuable space in the lab.
The TEA has become an industry go-to for nitrosamine testing and has set a high standard in this application in the food industry. Coupled with Ellutia’s Chemical Stripping System, the instrument is now seeing success in pharmaceutical testing.
