Nitrosamine impurities analysis solution guide
Souhrn
Význam tématu
Nitrosaminy představují potenciálně genotoxické a karcinogenní látky, jejichž přítomnost v léčivech může vést k bezpečnostním rizikům a globálním stažením produktů z trhu, jak ukázaly případy kontaminace sartanu v roce 2018.
Cíle a přehled studie
Cílem průvodce je popsat analytické strategie od sledování prekurzorů až po potvrzení výskytu nitrosaminů, zajistit splnění požadavků ICH M7(R1) a FDA a nabídnout řešení pro vysokou citlivost i výkonnou rutinní analýzu.
Použitá metodika a instrumentace
- Chromatografie: UHPLC/HPLC (Vanquish Flex, Vanquish Core, Acclaim PAII), GC (TraceGOLD TG-1701), RFIC HPIC (Dionex IonPac AS19-4 µm, ICS-6000)
- Hmotnostní spektrometrie: HRAM MS (Orbitrap Exploris 120, Q Exactive), Triple Quad MS/MS (TSQ Quantis, TSQ Altis, TSQ Fortis, TSQ 9000 GC-MS/MS)
- Autosampler: TriPlus RSH pro automatizaci vzorkování
- Software: Chromeleon CDS pro řízení přístrojů, zpracování dat a auditní stopu
Hlavní výsledky a diskuse
HRAM MS s rozlišením ≥ 120 000 dokáže rozlišit izotopy NDMA a DMF, čímž eliminuje falešně pozitivní nálezy. GC-HRAM metodika oddělí a kvantifikuje 15 nitrosaminů pod 2 ppb v čase < 12 min. LC-MS/MS dosahuje LOQ 5–10 ppb s opakovatelností přes 1 000 injekcí. RFIC-UV stanovuje nitrit s LOD ~ 0,9 µg/g API bez interferencí chloridů.
Přínosy a praktické využití metody
Nabízené platformy poskytují vysokou citlivost, robustní separaci, reprodukovatelnost, minimalizaci falešně pozitivních výsledků, automatizaci pracovních postupů a jednotnou softwarovou infrastrukturu pro QA/QC farmaceutických laboratoří.
Budoucí trendy a možnosti využití
Očekává se širší integrace HRAM MS a MS/MS v jednom workflow, pokročilá automatizace a digitální audity, využití umělé inteligence pro analýzu dat a rozšíření metod pro nové nitrosaminové nečistoty v raných fázích vývoje léčiv.
Závěr
Komplexní přístup spojující screening, potvrzení a automatizaci v souladu s regulačními požadavky nabízí farmaceutickým laboratořím efektivní a spolehlivou strategii pro detekci a kvantifikaci nebezpečných nitrosaminových nečistot.

Monitoring genotoxic impurities in pharmaceutical products
Since elevated levels of nitrosamines were detected in certain pharmaceuticals
as first reported in July 2018, finding the right solutions have become the major
focus for many pharmaceutical manufacturers. Thermo Fisher Scientific™ as a
trusted partner for pharmaceutical analysis and quality control offers several
solutions to fit your needs. We are your partner to:
• Monitoring the levels of class 1 genotoxic impurities, which are known
mutagenic carcinogens according to IARC and ICH M7(R1) regulatory
guidelines
• Avoid any risks of recalls of your drug products
• Effortlessly follow and satisfy regulatory guidelines

Why is nitrosamine impurity analysis in drugs important?
Nitrosamines are small molecular weight chemical substances that are
probable human carcinogens, and their presence in medicines is considered
unacceptable by regulators. They are organic compounds featuring a nitroso
group and amino group. They have the generic formula R
2N-N=O where
the R groups are typically alkyl in nature, they may be formed during API
manufacturing—from starting materials, intermediates, reactants, recycling of
solvents and the presence of nitrites and secondary amines.
In 2018, nitrosamine impurities, including NDMA, were discovered in Valsartan,
an Angiotensin II receptor blocker (ARB) medication used to treat high blood
pressure and heart failure. This led to a global recall of Valsartan and several
other ARB drugs.
First mostly N-Nitrosodimethylamine (NDMA) and N-Nitrosodiethylamine
(NDEA), two carcinogenic impurities were the target of careful monitoring
efforts. Since then, several other N-nitrosamines have also been identified
and are being investigated by regulators: N-Nitrosodiisopropylamine (NDIPA),
N-Nitrosoethylisopropylamine (NEIPA), N-Nitrosodibutylamine (NDBA), and
N-Nitroso-N-methyl-4-aminobutyric acid (NMBA).
The outcome that all events has made clear—there’s a recognized need for
a risk assessment strategy for potential nitrosamines in any pharmaceutical
product at risk for their presence.

Matrix interferences and or common solvents, such as DMF, from the
manufacturing process can lead to false-positive results with unit mass
resolution mass spectrometry. This is especially true if the interfering
compounds aren’t separated chromatographically.
We recommend Thermo Scientific™ Orbitrap™ technology as the gold standard
mass spectrometry technique as a minimum of 45k resolution is critical to
eliminate false-positive results. Whether you want to perform fast and confident
nitrosamine impurity screening and or peace-of-mind confirmatory analysis in
combination with triple quadrupole MS, HRAM MS should be a corner stone in
your workflow.

Triple quadrupole mass spectrometry is at the forefront of trace analysis
of nitrosamines in pharmaceuticals. We recommend using this technology
for screening and in harmony with HRAM for positive result confirmation to
eliminate false positive results. MS/MS can increase lab productivity and reduce
workload on your HRAM systems.
“ Did you know that this strategy is currently used in the same manner for dioxin analysis in
food and feed? Why? This is an established solution for maximal productivity and ultimate
confidence in results.”
