Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- Two New Zealand White (Hsdlf:NZW) strain rabbits were supplied by Harlan Laboratories UK Ltd., Leicestershire, UK. At the start of the study the animals weighed 2.96 or 3.23 kg and were twelve to twenty weeks old. After an acclimatization period of at least five days each animal was given a number unique within the study which was written with a black indelible marker pen on the inner surface of the ear and on the cage label.
The animals were individually housed in suspended cages. Free access to mains drinking water and food (2930C Teklad Global Rabbit diet supplied by Harlan Laboratories UK Ltd., Oxon, UK) was allowed throughout the study. The diet and drinking water were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study.
The temperature and relative humidity were set to achieve limits of 17 to 23 °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 twelve hours continuous light (06:00 to 18:00) and twelve 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.
Justification
The rabbit is the preferred species of choice as historically used for irritation studies and is specified in the appropriate test guidelines. The number of animals used was the minimum required to achieve the objectives of the study. Testing was conducted in two animals and the response in those animals was such that exposure of a third animal would not affect classification of the test item, therefore, no further testing was needed.
Test system
- Vehicle:
- unchanged (no vehicle)
- Remarks:
- For the purpose of the study the test item was used as supplied.
- Controls:
- other: EXAMPLE: The left eye remained untreated and was used for control purposes.
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit):
A volume of 0.1 mL of the test item, which was found to weigh approximately 96 mg (as measured by gently compacting the required volume into an adapted syringe) was placed into the conjunctival sac of the right eye, formed by gently pulling the lower lid away from the eyeball. The upper and lower eyelids were held together for about one second immediately after treatment, to prevent loss of the test item, and then released. The left eye remained untreated and was used for control purposes
VEHICLE
Not applicable, for the purpose of the study the test item was used as supplied. - Duration of treatment / exposure:
- 72 hours
- Observation period (in vivo):
- Approximately 1 hour, 24, 48 and 72 hours and 7 days following treatment.
- Number of animals or in vitro replicates:
- 2 males
- Details on study design:
- PRE STUDY:
Immediately before the start of the test, both eyes of the provisionally selected test rabbits were examined for evidence of ocular irritation or defect with the aid of a light source from a standard ophthalmoscope. Only animals free of ocular damage were used.
TESTING PROCEDURE:
Initially, a single rabbit was treated. A subcutaneous injection of buprenorphine 0.01 mg/kg was administered 60 minutes prior to test item application to provide a therapeutic level of systemic analgesia. Five minutes prior to test item application, a pre dose anesthesia of ocular anesthetic (two drops of 0.5% tetracaine hydrochloride) was applied to each eye.
Eight hours after test item application, a subcutaneous injection of post dose analgesia, buprenorphine 0.01 mg/kg and meloxicam 0.5 mg/kg, was administered to provide a continued therapeutic level of systemic analgesia. The treated animal was checked for signs of pain and suffering approximately 12 hours later. No further analgesia was required.
After consideration of the ocular responses produced in the first treated animal, a second animal was similarly treated.
Observations were made, 1, 24, 48 and 72 hours. Any clinical signs of toxicity, if present, were also recorded and bodyweights were recorded too. An additional observation was made in one treated eye on Day 7 to assess the reversibility of the ocular effects.
REMOVAL OF TEST SUBSTANCE
- Washing (if done):
Not applicable
- Time after start of exposure:
Not applicable
SCORING SYSTEM:
Assessment of ocular damage/irritation was made approximately 1 hour and 24, 48 and 72 hours following treatment, according to the draize scale which can be found from (Draize J H (1977) "Dermal and Eye Toxicity Tests" In: Principles and Procedures for Evaluating the Toxicity of Household Substances, National Academy of Sciences, Washington DC p.48 to 49). The Draize scoring system has been included in the any other information on methods section (including tables).
TOOL USED TO ASSESS SCORE:
Examination of the eye was facilitated by the use of the light source from a standard ophthalmoscope.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:

- Conclusions:
- The test item does not meet the criteria for classification according to Regulation (EC) No 1272/2008, relating to the Classification, Labelling and Packaging of Substances and Mixtures.
- Executive summary:
Introduction:
The study was performed to assess the irritancy potential of the test item to the eye of the New Zealand White rabbit.
Results:
A single application of the test item to the non-irrigated eye of two rabbits produced moderate conjunctival irritation. One treated eye appeared normal at the 72‑Hour observation and the other treated eye appeared normal at the 7‑Day observation.
Conclusion:
The test item does not meet the criteria for classification according to Regulation (EC) No 1272/2008, relating to the Classification, Labelling and Packaging of Substances and Mixtures.
