At 160 mg/kg postnatal viability and live-birth indices were decreased.
Applicant's summary and conclusion
- Conclusions:
- At doses of 20, 40, 80 and 180 mg/kg bw no maternal toxicity was observed. At 80 mg/kg bw urogenital syndrom (uni- and bilateral renal agenesis, hydronephrosis, incomlete formation of uterus) occured. No embryotoxicity was noted.
At 160 mg/kg postnatal viability and live-birth indices were decreased.
