A brief review on genotoxic impurities in pharmaceuticals

Genotoxic impurities (GTIs) in pharmaceuticals are increasing concern to pharmaceutical industries due to their potential for human carcinogenicity. The literature currently lacks the Guidance for the analytical determination of diverse classes of GTIs. This review article provides brief information regarding Genotoxic impurity (GTI), its sources, their classification, and existing regulatory approaches to control Genotoxic impurities in Pharmaceuticals, also information regarding different types of GTI and examples of each class. It is very difficult for researchers to detect GTI at Trace level so the detection method is also given in the chart, almost all the GTI are Mutagenic but as shown in Nitrosamines it is Mutagenic and its carcinogenicity is also proved but there are no such strong evidence and literature which shows genotoxicity. So, it is included as Mutagenic & carcinogenic. Different Control strategies to control Genotoxicity are also discussed.
