- DOSAGE PREPARATION:
The proper amount of the test article was measured according to volume since it was a liquid, and was allocated/dosed neat as received from the Sponsor at 2000 and 550 mg/kg with a pH=9. The stock bottle was inverted several times prior to dispensing. At 175 mg/kg the test article was dissolved in distilled water (175 mg brought to a volume of 5 mL). The resulting clear liquid had a pH equal to 12. - Doses:
- 175, 550 and 2000 mg/kg
- No. of animals per sex per dose:
- 6 rats in total:
2 female rats in the 175 mg/kg dose group
3 female rats in the 550 mg/kg dose group
1 female rat in the 2000 mg/kg dose group - Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Mortality checks were made at least once daily. Clinical observations were recorded prior to dosing, as well as at 30 minutes, 4 hours post-dose, and daily thereafter up to day 15. Body weights were recorded on the day of dosing (day 1), and on days 8 and 15, or upon death.
- Necropsy of survivors performed: yes, all surviving rats were euthanized by CO2 asphyxiation and necropsied on day 15. - Statistics:
- The LD50 was calculated for the main test using the AOT425StatPgm developed by Westat May, 2001.
Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- 550 mg/kg bw
- Based on:
- test mat.
- 95% CL:
- 88.94 - 2 430
- Mortality:
- 175 mg/kg: no mortality observed
550 mg/kg: two of three animals receiving the test article at 550 mg/kg were found dead
2000 mg/kg: the single animal at 2000 mg/kg was as well found dead - Clinical signs:
- other: No clinical signs were observed at 175 mg/kg or in the initial surviving animal at 550 mg/kg. Abnormal gait and stance, decreased activity, and decreased body tone were observed in the animal at 2000 mg/kg. In addition to these signs piloerection was obse
- Gross pathology:
- Terminal necropsy revealed no visible lesions in the surviving animals at 175 and 550 mg/kg. Necropsy of the animals found dead revealed lesions of the intestines and stomach including fluid-filled red, lining red and a dark red circular lesion.
Applicant's summary and conclusion
- Interpretation of results:
- Category 4 based on GHS criteria
- Conclusions:
- Based on the results of this study, the oral LD50 for the test substance in rats was estimated to be 550 mg/kg (95% PL Confidence interval of 88.94 to 2430 mg/kg).
