In November 2020, the Committee for Medicinal Products for Human Use (CHMP) of the EMA aligned recommendations for limiting nitrosamine impurities in sartan medicines with recommendations it issued for other classes of medicines. The main change concerns the limits for nitrosamines, which previously applied to the active ingredients but now apply instead to the finished products (e.g. tablets). These limits, based on internationally agreed standards (ICH M7(R1)), should ensure that the excess risk of cancer from nitrosamines in any sartan medicines is below 1 in 100,000 for a person taking the medicine for lifelong treatment.
