Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Clinical signs:
- other: Apathy, slightly reduced spontaneous activity, kyphosis, tremor, slight piloerection, half eyelid-closure; fully reversible within the same day.
- Other findings:
- Under the study conditions, a single oral application of the test item to rats at a dose of 300 mg/kg body weight was associated with no signs of toxicity or mortality. Furthermore, an oral application of the test item at a dose of 2000 mg/kg body weight was associated with signs of toxicity which were fully reversible within 4 hours to 24 hours post-dose.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The median lethal dose of the substance after a single oral administration to female rats, observed over a period of 14 days is LD50 cut-off (rat): > 2000 mg/kg <= 5000 mg/kg bw.
