Test animals
- Species:
- rat
- Strain:
- other: Wistar strain, Crl:WI (Han)
- Sex:
- female
- Details on test animals or test system and environmental conditions:
- - Source: Charles River Deutschland, Sulzfeld, Germany
- Age at study initiation: Young adult animals (approx. 9 weeks old)
- Weight at study initiation: Body weight variation was within +/- 20% of the sex mean (first group: 172 - 179 grams; second group: 177 - 196 grams).
- Fasting period before study: Animals were deprived of food overnight prior to dosing and until 3-4 hours after administration of the test substance. Water was available ad libitum.
- Housing: Group housing of 3 animals per cage in labeled Macrolon cages
- Diet: Free access to pelleted rodent diet (SM R/M-Z from SSNIFF® Spezialdiäten GmbH, Soest, Germany).
- Water: Free access to tap water.
- Acclimation period: At least 5 days
ENVIRONMENTAL CONDITIONS
Environmental controls for the animal room were set to maintain 18 to 24°C, a relative humidity of 40 to 70%, approximately 15 room air changes/hour, and a 12-hour light/12-hour dark cycle.
IN-LIFE DATES: From 12 to 29 June 2012
Administration / exposure
- Route of administration:
- oral: gavage
- Details on oral exposure:
- GAVAGE METHOD: plastic feeding tubes.
Frequency: single dosage, on Day 1.
VEHICLE Propylene glycol (Merck, Darmstadt, Germany) (specific gravity 1.036).
- Justification for choice of vehicle: The vehicle was selected based on trial formulations performed at WIL Research Europe and on test substance data supplied by the sponsor.
MAXIMUM DOSE VOLUME APPLIED: 2000 mg/kg (10 mL/kg) body weight.
Dose volume calculated as dose level (g/kg) / specific gravity.
DOSAGE PREPARATION: The formulations (w/w) were prepared within 4 hours prior to dosing. The test substance and formulation were protected from light by using amber-coloured glassware. Homogeneity was accomplished to a visually acceptable level. Adjustment was made for specific gravity of the vehicle. No correction was made for purity of the test substance. In order to obtain homogeneity, the test substance formulations were heated in a water bath with a maximum temperature of 30.0ºC for a maximum of 51 minutes. - Doses:
- 2000 mg/kg body weight
- No. of animals per sex per dose:
- 6 (2 groups of three females in a stepwise manner)
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
Mortality/Viability: Twice daily.
Body weights: Days 1 (pre-administration), 8 and 15.
Clinical signs: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15.
- Necropsy of survivors performed: At the end of the observation period, all animals were sacrificed by oxygen/carbon dioxide procedure and subjected to necropsy. Descriptions of all internal macroscopic abnormalities were recorded.
- Other examinations performed: none. - Statistics:
- No statistical analysis was performed (The method used is not intended to allow the calculation of a precise LD50 value).
Results and discussion

- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: Hunched posture and/or piloerection were noted in all animals on Day 1. In addition, one animal showed uncoordinated movements on Day 1.

- No abnormalities were found at macroscopic post mortem examination of the animals.
Applicant's summary and conclusion
- Conclusions:
- An acute oral LD50 >2000 mg/kg bw was determined for the test substance.
- Executive summary:
The acute oral toxicity test was conducted according to OECD guideline 423, EU method B.1, EPA OPPTS 870.1100, JMAFF guidelines, and GLP principles. Female wistar rats were dosed 2000 mg/kg bw of test substance by gavage. No mortality or abnormal findings were reported. An acute oral LD50 >2000 mg/kg bw was determined for the test substance (Wil, 2012).
