Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Remarks:
- Hsd:SD strain
- Sex:
- female
- Details on test animals or test system and environmental conditions:
- Sprague Dawley (Hsd:SD) strain rats were supplied by Envigo RMS (UK) Limited, Oxon, UK. On receipt the animals were randomly allocated to cages. The females were nulliparous and non-pregnant. After an acclimatization period of at least 5 days the animals were selected at random and given a number unique within the study by indelible ink-marking on the tail and a number written on a cage card. At the start of the study the animals were 8 to 12 weeks of age. The body weight variation did not exceed ±20% of the mean body weight at the start of treatment.
Animal Care and Husbandry
The animals were housed in groups of up to four in suspended solid-floor polypropylene cages furnished with woodflakes. With the exception of an overnight fast immediately before dosing and for approximately 3 to 4 hours after dosing, free access to mains drinking water and food (2014C Teklad Global Rodent diet supplied by Envigo RMS (UK) Limited, Oxon, UK) was allowed throughout the study. The diet, drinking water and bedding were routinely analyzed and were considered not to contain any contaminants that would reasonably be expected to affect the purpose or integrity of the study.
The temperature and relative humidity were set to achieve limits of 19 to 25 °C and 30 to 70% respectively. The rate of air exchange was at least fifteen changes per hour and the lighting was controlled by a time switch to give 12 hours continuous light and 12 hours darkness.
The animals were provided with environmental enrichment items which were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- CMC (carboxymethyl cellulose)
- Details on oral exposure:
- Test Item Preparation and Analysis
For the purpose of the study the test item was freshly prepared, as required, as a suspension in 0.5% carboxymethyl cellulose. 0.5% carboxymethyl cellulose was used for consistency with previously performed tests.
The test item was formulated within 2 hours of being applied to the test system. It is assumed that the formulation was stable for this duration.
No analysis was conducted to determine the homogeneity, concentration or stability of the test item formulation. This is an exception with regard to GLP and has been reflected in the GLP compliance statement
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 the fasted body weight at the time of dosing. Treatment of animals was sequential. Sufficient time was allowed between each dose group to confirm the survival of the previously dosed animals. - Doses:
- 300 and 2000 mg/kg
- No. of animals per sex per dose:
- 300 mg/kg = 1
2000 mg/kg = 5 - Control animals:
- no
- Details on study design:
- In the absence of data regarding the toxicity of the test item, 300 mg/kg was chosen as the starting dose.
Dose Level (mg/kg) Concentration (mg/mL) Dose Volume (mL/kg) Number of Rats
300 30 10 1
In the absence of toxicity at a dose level of 300 mg/kg, an additional animal was treated as follows:
Dose Level (mg/kg) Concentration (mg/mL) Dose Volume (mL/kg) Number of Rats
2000 200 10 1
In the absence of mortality 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
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 the fasted body weight at the time of dosing. Treatment of animals was sequential. Sufficient time was allowed between each dose group to confirm the survival of the previously dosed animals.
Clinical observations were made 30 minutes, 1, 2, and 4 hours after dosing and then daily for 14 days. Morbidity and mortality checks were made twice daily, early and late during normal working days, and once daily at weekends and public holidays.
Individual body weights were recorded on Day 0 (the day of dosing) and on Days 7 and 14.
At the end of the observation period the surviving 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.
Data Evaluation
The test item was classified according to Annex 3 of the OECD Guidelines for Testing of Chemicals No. 420 "Acute Oral Toxicity - Fixed Dose Procedure" (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 body weights 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:
- GHS criteria not met
- Conclusions:
- The acute oral median lethal dose (LD50) of the test item in the female Sprague Dawley strain rat was estimated to be greater than 2000 mg/kg body weight (Globally Harmonized Classification System - Unclassified).
- Executive summary:
The study was performed to assess the acute oral toxicity of the test item in the Sprague Dawley strain rat.
Methods
Following a sighting test at dose levels of 300 mg/kg and 2000 mg/kg, a further group of four fasted females was given a single oral dose of test item, as a suspension in 0.5% carboxymethyl cellulose, at a dose level of 2000 mg/kg body weight. Clinical signs and body weight development were monitored during the study. All animals were subjected to gross necropsy.
Results
Mortality. There were no deaths.
Clinical Observations. There were no signs of systemic toxicity.
Body Weight. All animals showed expected gains in body weight.
Necropsy. No abnormalities were noted at necropsy.
Conclusion
The acute oral median lethal dose (LD50) of the test item in the female Sprague Dawley strain rat was estimated to be greater than 2000 mg/kg body weight (Globally Harmonized Classification System- Unclassified).
