Applicant's summary and conclusion
- Conclusions:
- No Observed Adverse Effect Level (NOAEL) for maternal toxicity was considered to be 500 mg/kg/day, As no indications of any influence on reproductive parameters and No developmental toxic effects were seen up to the highest dose of 500 mg/kg bw . When male and female wistar rats were treated with test material orally up to 3 generation.
- Executive summary:
Reproductive and development toxicity study oftestmaterial was performed on male and femaleHarlan-Wistar rats. Test material administered in diet for up to 3 generation. 10 male and 20 females were used. Asno indications of any influence on
maternal weight gain, reproductive parameters andNo developmental toxic effects were seen up to the highest dose of 500 mg/kg bw, Hence No Observed Adverse Effect Level (NOAEL) for maternal toxicity was considered to be 500 mg/kg/day.When male and femalewistar rats were treated withtest materialorally up to 3 generation.
