Аннотация:According to the literature genotoxic properties of about a half of hypoglycemic drugs have not been investigated in accordance with the recommended methodology, and studies of the mutagen-modifying activity of antidiabetic drugs are sporadic. Based on the available published data, it is impossible to conclude about either presence or absence of genotoxic / antigenotoxic potential of antidiabetic drugs. There is evidence of the antimutagenic activity of metformin; in relation to other drugs, studies of mutagen-modifying activity have not been carried out or are represented only by a few articles. Further study of the genotoxic properties of hypoglycemic drugs is required in accordance with modern approaches and requirements, as well as an assessment of their mutagen-modifying activity.
