- Clinical Observations
Limit test animals were observed for clinical abnormalities at approximately 1, 2, 4, 8 and 24 hours (post-dose) and daily thereafter (days 1-14). A general health/mortality check was performed twice daily (in the morning and in the afternoon).
Body Weights
Individual body weights were obtained for the limit test animals prior to fasting (day -1), prior to dosing on day 0 and on days 7 and 14.
Food Consumption
Individual food consumption was recorded for all animals on days 0, 7 and 14.
Scheduled Euthanasia
All limit test animals were euthanized by carbon dioxide inhalation at study termination (day 14) and necropsied. Body cavities (cranial, thoracic, abdominal and pelvic) were opened and examined. No tissues were retained. - Statistics:

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of this test, the acute oral LD50 was estimated to be greater than 2000 mg/kg in the rat.
- Executive summary:
The single-dose oral toxicity was evaluated in Sprague-Dawley rats. A limit test was performed in which one group of five male and five female rats received a single oral administration of the test article at a dose of 2000 mg/kg body weight. Following dosing, the limit test rats were observed at 1,2,4, 8 and 24 hours post-dose and daily thereafter and weighed weekly. Individual food consumption was recorded weekly. A gross necropsy examination was performed on all limit test animals at the time of scheduled euthanasia (day 14). No mortality occurred during the limit test. The most notable clinical abnormalities observed during the study included fecal/urine stain, mucoid/soft stools, diarrhea, congested breathing and dark material around the nose/eyes. Body weight gain and adequate food consumption were noted for all animals during the test period. No gross internal findings were observed at necropsy on study day 14.
