Description of key information
No signs of systemic toxicity have been observed in the repeated dose toxicity study.
Key value for chemical safety assessment
Repeated dose toxicity: via oral route - systemic effects
Link to relevant study records
- Endpoint:
- short-term repeated dose toxicity: oral
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 407 (Repeated Dose 28-Day Oral Toxicity Study in Rodents)
- GLP compliance:
- yes
- Limit test:
- no
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- male/female
- Route of administration:
- oral: unspecified
- Vehicle:
- other: 1% metthylcellulose
- Analytical verification of doses or concentrations:
- not specified
- Duration of treatment / exposure:
- 28 days plus 2 week recovery period for control (5 males/5 females) and top dose animals (5 males/5 females).
- Frequency of treatment:
- The test substance in a 1% metthylcellulose vehicle (1o ml) was administered daily by gavage.
- Remarks:
- Doses / Concentrations:
15, 150 and 1000 mg/kg bw/day
Basis:
other: nominal in test vehicle - No. of animals per sex per dose:
- 10 males and 10 females in the control group
5 males and 5 females at 15 /mg/kg bw/day
5 males and 5 females at 150 /mg/kg bw/day
10 males and 10 females at 1000 /mg/kg bw/day - Control animals:
- yes, concurrent vehicle
- Observations and examinations performed and frequency:
- One female was foun dead in week one, but this was considered to be accidental.
- Sacrifice and pathology:
- No treatment-related changes were observed.
- Other examinations:
