Modern Approaches to Estimating the Content of Genotoxic Impurities in Drugs (a Review)

Abstract

This review considered international approaches to assessment of the content of genotoxic impurities (residual solvents and various inorganic and organic impurities) in drugs. Foreign and domestic regulations defining requirements for the classification, control, and toxicological risk assessment of potential genotoxic impurities in drug substances and drugs were compared. The use of highly sensitive and specific analytical methods for detecting genotoxic impurities in drugs was justified. The need to improve the domestic regulatory framework on the control of elemental genotoxic impurities (heavy metals) and to prepare guidelines on the assessment of potentially genotoxic organic impurities in drugs was demonstrated.
