Applicant's summary and conclusion
- Interpretation of results:
- Category 5 based on GHS criteria
- Conclusions:
- The oral LD50 of ERGP-IEM is greater than 2000 mg/kg of body weight in female rats and is considered to be in GHS Category 5.
- Executive summary:
The objective of this study was to determine the potential for toxicity of ERGP-IEM when administered orally. The study was conducted according to GLP. The test method was conducted based on the OECD Guideline no. 423 (2001). Six healthy female Sprague Dawley rats were dosed orally with ERGP-IEM at 2000 mg/kg. The rats were observed at 15 (± 5) minutes, 1-, 2-, and 4-hours post-dosing and at least once daily for 14 days. All animals were observed twice daily for mortality on Day 1 to Day 14. Body weights were recorded pretest, weekly, and at termination.
All animals survived the study.Abnormal physical signs including ataxia, piloerection, chromorhinorrhea, dyspnea, and diminished fecal output were observed among all six animals within 24 hours following dose administration. From 48 hours post-dosing to study termination, no abnormal physical signs were observed. The gross necropsy revealed no observable abnormalities among five out of six animals. Pale areas were observed on the liver of one animal.
The oral LD50 of ERGP-IEM is greater than 2000 mg/kg of body weight in female rats and is considered to be in GHS Category 5.
