As nitrosamines are known as probable carcinogens, the marketing authorization holders and drug manufactures should take the responsibility to evaluate the risk by performing nitrosamine testing of API, excipients, and package system through the drug product shelf life using globally recognized test methods. The nitrosamine impurities level should be controlled below the acceptable limits based on compliance with ICH M7 (R1) [Assessment and Control of DNA Reactive (Mutagenic) Impurities in Pharmaceuticals to Limit Potential Carcinogenic Risk] requirements.
