- Dose descriptor:
- LD50
- Effect level:
- 4 200 mg/kg bw
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- 2 800 mg/kg bw
- Mortality:
- Male Rats: No deaths occurred at the two lowest dose levels (1259 and 2000 mg/kg). Single oral doses of 3162 and 4000 mg/kg produced 3/10 and 4/10 deaths,respectively. Six animals (out of 10) died at both of the highest dose levels (4487 and 5000 mg/kg).
Female Rats: Ten females were administered single oral doses of 794 and 1259 mg/kg – these produced 0/10 deaths in both cases. Further single oral doses of 2000, 3162, 3565, 4000 and 5000 mg/kg produced 1/10, 3/10, 8/10, 9/10 and 10/10 deaths, respectively. - Clinical signs:
- Adverse clinical signs included depression, tremors, lacrimation, salivation, convulsions (females only) and hyperactivity (females only) .
No abnormalities were observed in males at necropsy. Females were found to have bloated caecums and/or stomachs. - Body weight:
- no data
- Gross pathology:
- no data
- Other findings:
- no data
Any other information on results incl. tables
The oral LD50 was 4200 mg/kg in male rats and 2800 mg/kg in female rats. Adverse clinical signs included depression, tremors, lacrimation, salivation, convulsions (females only) and hyperactivity (females only) .
