Frequency: single dosage, on Day 1.
VEHICLE
The vehicle was selected based on trial preparations.
DOSAGE PREPARATION
The formulations (w/w) were prepared within 4 hours prior to dosing. Homogeneity was accomplished to a visually acceptable level. Adjustment was made for specific gravity of vehicle. - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 3
- Control animals:
- no
- Details on study design:
- The toxicity of the test substance was assessed by stepwise treatment of groups of 3 animals. The first group was treated at a dose level of 2000 mg/kg body weight. The absence or presence of mortality of animals dosed at one step determined the next step, based on the test procedure defined in the guidelines. The onset, duration and severity of the signs of toxicity were to be taken into account for determination of the time interval between the dose groups.
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Mortality/Moribundity checks: Twice daily
Body weights: Days 1 (pre-administration), 8 and 15.
Clinical signs: At periodic intervals on the day of dosing and once daily thereafter, until day 15.
- Necropsy of survivors performed: All animals assigned to the study were subjected to necropsy and descriptions of all internal macroscopic abnormalities recorded.
- Other examinations performed: none.
Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- Male: 2000 mg/kg bw; Number of animals: 3; Number of deaths: 0
Female: 2000 mg/kg bw; Number of animals: 3; Number of deaths: 0 - Clinical signs:
- other: Signs of toxicity related to dose levels: Lethargy, hunched posture, rales, uncoordinated movements and/or chromodacryorrhoea were noted among the animals between days 1 and 3.
- Body weight:
- lower than 10% body weight loss
- Remarks:
- The mean body weight gain shown by the animals over the study period was considered to be similar to that expected of normal untreated animals of the same age and strain.
- Gross pathology:
- No abnormalities were found at macroscopic post mortem examination of the animals.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In an acute oral toxicity study performed according to OECD 423 and in accordance with GLP principles, an LD50 of >2000 mg/kg bw was determined
- Executive summary:
The acute oral toxicity of SPS-1 00 was determined in accordance with OECD guideline 423 and according to GLP principles. The substance was administered by oral gavage to two consecutive groups of 3 Wistar Han rats of each sex at 2000 mg/kg body weight. No mortality occurred. Lethargy, hunched posture, rales, uncoordinated movements and/or chromodacryorrhoea were noted among the animals between days 1 and 3. The body weight gain shown by the animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain. No abnormalities were found at macroscopic post mortem examination of the animals. The acute oral toxicity (LD50) was determined to be > 2000 mg/kg bw.
