Abstract
In 2018, some sartan medicinal products were reported to be contaminated with nitrosamine compounds, which are potent mutagenic carcinogens. Two nitrosamines received particular attention: N -nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA). These have since been confirmed in different types of medicinal products, including ranitidine and metformin. Consequently, the European Medicines Agency (EMA) started an investigation into the cause of contamination and an assessment of the risk to patients taking contaminated medicinal products. The main source of contamination were changes in production, which involves combinations of amines and nitrogen compounds and the use of specific catalysts and reagents. Withdrawals of medicinal products that took place in Croatia did not lead to a shortage of sartan- or metformin-containing medicines. Moreover, ranitidine had been preventively withdrawn all over the EU, including Croatia, creating shortages at the time, but was subsequently replaced with therapeutic alternatives.

In 2018, some sartan medicinal products were reported to be contaminated with nitrosamine compounds, which are potent mutagenic carcinogens
They can be found in water, food, tobacco, pesticides, or plastics, but received public attention in mid-2018, when they were found in medicinal products [1]
Once N-nitrosamines are activated by microsomal liver enzymes, they can react with DNA base pairs to form unstable α-hydroxyalkylnitrosamines and produce alkyldiazonium ions, which alkylate DNA bases and induce carcinogenic response [5]
Summary
In 2018, some sartan medicinal products were reported to be contaminated with nitrosamine compounds, which are potent mutagenic carcinogens. Two nitrosamines received particular attention: N-nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA). These have since been confirmed in different types of medicinal products, including ranitidine and metformin. Nitrosamines are a group of organic compounds containing the nitroso functional group They can be found in water, food, tobacco, pesticides, or plastics, but received public attention in mid-2018, when they were found in medicinal products [1]. The two best-known nitrosamines, N-nitrosodimethylamine (NDMA) and N-nitrosodiethylamine (NDEA), have been classified by the International Agency for Research on Cancer (IARC) as possible human (class 2A) carcinogens, but they are genotoxic [3, 4]. Once N-nitrosamines are activated by microsomal liver enzymes, they can react with DNA base pairs to form unstable α-hydroxyalkylnitrosamines and produce alkyldiazonium ions, which alkylate DNA bases and induce carcinogenic response [5]
