Results and discussion
Applicant's summary and conclusion
- Conclusions:
- Based on data of multiple mutagenicity tests with a variety of lithium salts it is concluded that lithium salts lack mutagenicity.
Consequently, lithium, being the toxicological relevant moiety has not to be considered as a genotoxic or clastogenic substance. - Executive summary:
The authors summarized the results of in vitro and in vivo mutagenicity , DNA damage , CA and SCE tests with various lithium salts. Several studies reported genotoxic effects of various lithium compounds at high doses (equivalent to therapeutic doses or higher), whereas many other studies have failed to demonstrate an effect. The Nordic Expert Group stated, that considering the chemical properties of the lithium compounds it is unlikely that they act as direct mutagens. A possible explanation to the genotoxicity observed might be a secondary effect of increased cell survival caused by lithium’s inhibition of GSK3.
Based on the conclusion of the authors, lithium hydroxide (formed following contact of lithium with aqueous solutions) and thereby lithium (in a read across approach) could be considered not genotoxic or clastogenic substance.
