Criteria used for interpretation of results: EU
Conclusions:
The oral LD50 in Wistar rats was established as exceeding 2000 mg/kg body weight.
Executive summary:

The test item was administered by oral gavage to three Wistar rats of each sex at 2000 mg/kg body weight. No mortality occurred. Lethargy, hunched posture, ventre-lateral recumbency, uncoordinated movements and piloerection were observed in the majority of animals between days 1 and 2. Rales were noted in one animal on day 3. No abnormalities were found in the animals at macroscopic post mortem examination. The oral LD50 value of the test item in Wistar rats was established as exceeding 2000 mg/kg body weight.
