Applicant's summary and conclusion
- Conclusions:
- The male and female parental animals exhibited no alteration in reproductive parameters.
On examination of neonates, there were no alterations in developmental parameters.
The NOAELs for reproductive/developmental toxicity are considered to be 1000 mg/kg/day or more for reproductive performance of male and female parental animals and for offspring development.
