The limits for nitrosamines in medicines have been set using internationally agreed standards (ICH M7(R1)) based on lifetime exposure. [12] Generally, people should not be exposed to a lifetime risk of cancer exceeding 1 in 100,000 from nitrosamines in their medicines. [ 12 ]
In the 1980s, the European Union began harmonising regulatory requirements. In 1989, Europe, Japan, and the United States began creating plans for harmonisation. The International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) was created in April 1990 at a meeting in Brussels.
The organic chemistry of nitrosamines is well developed with regard to their syntheses, their structures, and their reactions. [7] [8] They usually are produced by the reaction of nitrous acid (HNO 2) and secondary amines, although other nitrosyl sources (e.g. N 2 O 4, NOCl, RONO) have the same effect: [9] HONO + R 2 NH → R 2 N-NO + H 2 O
In August 2020, the European Medicines Agency (EMA) provided guidance to marketing authorization holders on how to avoid the presence of nitrosamine impurities in human medicines and asked them to review all chemical and biological human medicines for the possible presence of nitrosamines and to test the products at risk.

The CTD is maintained by the International Council on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). [ 1 ] [ 2 ] After the United States, European Union and Japan, the CTD was adopted by several other countries including Canada [ 3 ] and Switzerland.
The minimum essential documents that are required for the registration of pharmaceutical products designed for human use are specified in the document 'ICH Good Clinical Practices,' published in 1997 by the ICH [2] Example ICH essential documents that would be required in any US, EU or Japan based clinical trial would include: signed protocol ...
Losartan, the first ARB. Angiotensin II receptor blockers (ARBs), formally angiotensin II receptor type 1 (AT 1) antagonists, [1] also known as angiotensin receptor blockers, [2] [3] angiotensin II receptor antagonists, or AT 1 receptor antagonists, are a group of pharmaceuticals that bind to and inhibit the angiotensin II receptor type 1 (AT 1) and thereby block the arteriolar contraction and ...
Among the tobacco-specific nitrosamines, nicotine-derived nitrosamine ketone (NNK) and N-nitrosonornicotine (NNN) are the most carcinogenic. [1] Others include N ′-nitrosoanatabine (NAT) and N-nitrosoanabasine (NAB). NNK and its metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) are potent systemic lung carcinogens in rats ...
