Applicant's summary and conclusion

Interpretation of results:
highly irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
FR-513 was found to have effects on the eyes of the rabbits which completely resolved after 7 or 14 days in two animals. In one animal some of the effects persisted until 21 d (the maximal observation period).
Executive summary:

FR-513 was instilled into the test eyes of 3 NZ white rabbits at a dose of 84.6, 84.8 or 84.7 mg. Each eye was held closed for approx. 1 sec after administration. Observations were made 1, 24, 48 and 72 hours and 7, 14 and/or 21 after instillation.

Under the conditions of the study FR-513 was found to have effects on the eyes of the rabbits, which completely resolved after 7 or 14 days in two animals.

In one animal some of the effects persisted until 21 days (maximum observation period)

Based on the study results, FR-513 is classified as irritating to eyes in the EU.
