Key value for chemical safety assessment

Additional information

There are multiple reliable studies with losartan potassium on mutagenicity, including in vitro and in vivo, all of which have a negative result. Therefore, it can be concluded by read-across that losartan free acid is also non-genotoxic.


Justification for selection of genetic toxicity endpoint
in vivo study

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

The analogue substance, and therefore also losartan free acid, does not meet the criteria for classification as a mutagen according to DSD or CLP regulations.
