Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Diss Factsheets

Administrative data

Endpoint:
in vivo mammalian germ cell study: cytogenicity / chromosome aberration
Remarks:
Type of genotoxicity: chromosome aberration
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
weight of evidence
Study period:
2012
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
A reliable secondary source, summarising Rabeprazole pharmaco-toxicological properties, was used. However the primary sources were not revisited in order to verify their contents; for this reason reliability score 2 was used. The used secondary source has been updated on 2012; therefore it covers the most updated literature on the substance.

Any other information on results incl. tables

Rabeprazole was negative in the in vivo mouse micronucleus test, and the in vivo and ex vivo rat hepatocyte unscheduled DNA synthesis (UDS) tests.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): negative
The micronucleus and unscheduled DNA synthesis tests do not show any mutagen toxicity.
