Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- corn oil
- Remarks:
- Concentration : 30 and 200 mg/ml
- Details on oral exposure:
- Dosing
Frequency of treatment : Once only, on the day of dosing (Day 1).
Fasting procedure : Overnight prior to dosing (Day –1) up to 4 hours after dosing.
Dose calculation : Dose volume of 10 ml/kg of body weight for each animal.
Dosing method : By gavage, using a rubber catheter attached to a graded syringe. - Doses:
- Since information available suggested a possible mortality at the dose level of 2000 mg/kg, a first sub-group of 3 female animals was dosed at a level of 300 mg/kg (Step 1). Mortality did not occur. A second sub-group, similarly composed, was then dosed at the same dose level (step 2). No mortality occurred. Consequently, a first subgroup of 3 females was dosed at 2000 mg/kg. Since mortality occurred in the three animals, no further doses were investigated since the objective of the study had been achieved.
- No. of animals per sex per dose:
- 3 female animals/subgroup
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations: mortality and morbidity: twice daily; clinical signs: day of dosing (on dosing, approximately 0.5, 2 and 4h after dosing), daily thereafter (14 days); body weight: allocation (day-1), days 1,2,8 and 15.
- Necropsy of survivors performed: yes
Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 300 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality was observed in the female animals initially dosed at 300 mg/kg (steps 1 and 2).
Mortality occurred in the three female animals subsequently dosed at 2000 mg/kg (step 3). - Clinical signs:
- other: At 300 mg/kg bw, reduced activity, piloerection, hunched posture and semiclosed eyes were recorded on the day of dosing. The 3 female animals of step 1 showed piloerection on Day 2, recovery was completed by Day 3. In the 3 females of step 2 recovery occu
- Gross pathology:
- No abnormalities were observed at necropsy examination performed on all of the animals dosed at 300 mg/kg (steps 1 and 2) at the end of the observation period.
No abnormalities were recorded at necropsy examination in the two animals dosed at 2000 mg/kg and found dead on Day 2.
In the third animal dosed at the same dose level and found dead on Day 3, abnormal contents (dark, mucoid) were detected in the stomach, jejunum and ileum.
External abnormalities were limited to yellow staining in the urogenital region and brown staining on the muzzle.
Applicant's summary and conclusion
- Interpretation of results:
- Toxicity Category IV
- Remarks:
- Migrated information H302: Harmful if swallowed. Criteria used for interpretation of results: EU
- Conclusions:
- These results indicate that the test item, KETOPROFEN/BPPN, has a toxic effect on the rat following oral administration of a single dose at a level of 2000 mg/kg. The lack of mortality demonstrates the LD50 to be greater than 300 mg/kg body weight.
