- Wistar
- Sex:
- female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Harlan Laboratories UK Ltd., Oxon, UK;
- Age at study initiation: eight to twelve weeks of age;
- Weight at study initiation: The bodyweight variation did not exceed ±20% of the bodyweight of the initially dosed animal;
- Fasting period before study: an overnight fast immediately before dosing and for approximately three to four hours after dosing;
- Housing: in groups of up to four in suspended solid floor polypropylene cages furnished with woodflakes.
- Diet (e.g. ad libitum): ad libitum;
- Water (e.g. ad libitum): ad libitum;
- Acclimation period: 5 days
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19 to 25
- Humidity (%): 30 to 70
- Air changes (per hr): 15
- Photoperiod (hrs dark / hrs light): 12/12
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- arachis oil
- Details on oral exposure:
- All animals were dosed once only by gavage using a metal cannula attached to a graduated syringe.
VEHICLE
- Concentration in vehicle: 200 mg/mL
- Justification for choice of vehicle: the arachis oil BP was used because the test item did not dissolve/suspend in distilled water.
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg bw - Doses:
- 2000 mg/kg
- No. of animals per sex per dose:
- 5 females at 2000 mg/kg
- Control animals:
- no
- Details on study design:
- Using available information on the toxicity of the test item, 2000 mg/kg was chosen as the starting dose.
Dose Level (mg/kg) Concentration (mg/mL) Dose Volume (mL/kg) Number of Rats (Female)
2000 200 10 1
In the absence of mortality or evident toxicity at a dose level of 2000 mg/kg, an additional group of animals was treated as follows:
Dose Level (mg/kg) Concentration (mg/mL) Dose Volume (mL/kg) Number of Rats (Female)
2000 200 10 4
A total of five animals were therefore treated at a dose level of 2000 mg/kg in the study.
All animals were dosed once only by gavage using a metal cannula attached to a graduated syringe. The volume administered to each animal was calculated according to its fasted bodyweight at the time of dosing.
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: clinical observations were made ½, 1, 2, and 4 hours after dosing and subsequently once daily for fourteen days. Morbidity and mortality checks were made twice daily.
Individual bodyweights were recorded on Day 0 (the day of dosing) and on Days 7 and 14.
- Necropsy of survivors performed: yes. At the end of the observation period the animals were killed by cervical dislocation. All animals were subjected to gross necropsy. This consisted of an external examination and opening of the abdominal and thoracic cavities. The appearance of any macroscopic abnormalities was recorded. No tissues were retained.
- Other examinations performed: no

Evaluation of Data
The test item will be classified according to Annex 3 of the OECD Guidelines for Testing of Chemicals No. 420 "Acute Oral Toxicity - Fixed Dose Method" (adopted 17 December 2001).
Evaluation of data included identification of the number of animals that died during the study (or that were killed for humane reasons), and determination of the nature, severity, onset and duration of the toxic effects. If possible, the signs of evident toxicity were described. Evident toxicity refers to the toxic effects of sufficient severity that administration of the next higher dose level could result in development of severe signs of toxicity and probable mortality. Effects on bodyweights and abnormalities noted at necropsy were also identified.
Using the mortality data obtained, an estimate of the acute oral median lethal dose (LD50) of the test item was made.

Applicant's summary and conclusion
- Interpretation of results:
- study cannot be used for classification
- Remarks:
- Migrated information
- Conclusions:
- The acute oral median lethal dose (LD50) of the test item in the female Wistar strain rat was estimated to be greater than 2000 mg/kg bodyweight (Globally Harmonised Classification System - Unclassified).
- Executive summary:
Introduction. The study was performed to assess the acute oral toxicity of the test item in the Wistar strain rat. The method was designed to be compatible with the following:
OECD Guidelines for Testing of Chemicals No 420 “Acute Oral Toxicity - Fixed Dose Method” (adopted17 December 2001)
Method B1bis Acute Toxicity (Oral) of Commission Regulation (EC) No. 440/2008
Method. Following a sighting test at a dose level of 2000 mg/kg, an additional four fasted female animals were given a single oral dose of test item, as a solution in arachis oil BP, at a dose level of 2000 mg/kg bodyweight. Clinical signs and bodyweight development were monitored during the study. All animals were subjected to gross necropsy.
Mortality. There were no deaths.
Clinical Observations. There were no signs of systemic toxicity.
Bodyweight. All animals showed expected gains in bodyweight.
Necropsy. Raised limiting ridge in the stomach was noted at necropsy of one animal. No abnormalities were noted at necropsy of the remaining animals.
Conclusion. The acute oral median lethal dose (LD50) of the test item in the female Wistar strain rat was estimated to be greater than 2000 mg/kg bodyweight (Globally Harmonised Classification System - Unclassified).
