Applicant's summary and conclusion
- Conclusions:
- The results were:-NOAEL maternal toxicity >= 300 mg/kg bw /day-NOAEL reproductive toxicity>= 1000 mg/kg bw/day-NOAEL offspring development >= 1000 mg/kg bw/day
- Executive summary:
The aim of the test was to study the reproductive and developmental toxicity in rats (12 males and 12 females) in a combined repeated dose toxicity study with the reproductive / developmental toxicity screening test at doses of 100, 300 and 1000 mg/kg bw/day.
The test was performed according to OECD Test Guideline 422.
The results were:
-NOAEL maternal toxicity >= 300 mg/kg bw /day
-NOAEL reproductive toxicity>= 1000 mg/kg bw/day
-NOAEL offspring development >= 1000 mg/kg bw/day
