- Details on exposure:
- PREPARATION OF DOSING SOLUTIONS:
The test item was dissolved in sterile water. The vehicle was chosen based on the test item’s solubility. The test item formulation was prepared freshly on each administration day before the administration procedure. - Analytical verification of doses or concentrations:
- yes
- Details on analytical verification of doses or concentrations:
- The assessment of homogeneity as well as a determination of the nominal concentration of the test item in the vehicle was performed on samples collected at at various intervals.
Samples for analysis of the dose formulations of the test item in the vehicle (nominal concentration) were taken in the first and last week of the study for all doses.
Samples for homogeneity were taken from the top, middle and bottom of the high dose and low dose preparation. Samples were taken in the first and last week of the study.
All formulation samples were stored at -20 °C and analyzed after completion of the in-life phase of the toxicity study at BSL BIOSERVICE Scientific Laboratories GmbH under the BSL study no. 100380. - Details on mating procedure:
- After acclimatisation, females were paired with males as per the ratio of 1:2 (male to female). Females were paired for cohabitation in batches in order to regularize the number of animals for terminal sacrifice on particular day. The subsequent morning and the next morning onwards, the vaginal smear of female was checked to confirm the pregnancy. The day on which sperms were observed in the vaginal smear was considered as gestation day ‘0’. Mated females were assigned in an unbiased manner to the control and treatment groups ensuring that group mean body weights were comparable with each other.

Clinical Observation:
Few major clinical signs observed were slightly reduced sponstaneous activity, piloerection, vocalisation, aelopecia and blue coloured feces. These various clinical signs in treatment and control group were not considered to be test item related.
Prenatal Data:
Statistically significant increase in group mean number of male fetuses in MD and HD group and sex ratio in HD group was observed when compared with controls. Group mean number of females was decreased in MD and HD group withought reaching statistical significance. This significant difference in various parameters was attributed to the gender imbalance and reason for this effect could not be established in this study.
Litter Data:
Statistically significant increase in group litter mean weight and male litter weight was observed in MD and HD when compared with controls. There was also decrease in female litter weight observed in HD when compared with controls. Group mean number of males was increased in MD and HD and group mean number of females was decreased in MD and HD as compared to controls. Total Number of fetuses remained unaffected in treated groups when compared with controls. This significant difference in various litter data parameters was attributed to the gender imbalance and reason for this effect could not be established in this study.
Gross Pathology:
The terminally sacrificed animals belonging to the control and treatment groups revealed lesions like kidney cyst, pale kidneys, lung with white spots. There was increased number of incidences of blue/green discolouration of various visceral organs observed in treated groups and which could be attributed to the blue colur of the test item and as such of no toxicological significance.
The pattern of gross pathological lesions at necropsy in very few animals from different treatment groups suggested that the lesions were of spontaneous/ incidental in nature.

- Embryotoxic / teratogenic effects:no effects
Details on embryotoxic / teratogenic effects:
Few gross external abnormalities were seen among the control and treatment groups. Predominant external finding noted was haematoma on various body locations in control and treated groups.
Skeletal examination of the Alizarin red stained fetuses revealed a range of abnormalities which were of a type or which occurred at an incidence comparable in treated groups when compared with controls. Statistically significant increase in incidence of incomplete ossification of 5th and 6th sternebra and significant decrease in incidences of ansent 4th metacarpal (bilateral) was observed in LD and HD resepectively. However, due to lack of dose dependency in this effect indicates no relevance with treatment. There was no indication of a compound related trend in the type and incidences of other abnormalities and they were therefore considered to be spontaneous in nature.
Internal observation of the fetal viscera by free hand microdissection technique revealed a range of visceral abnormalities in all groups including control. There was statistically significant decrease in kidney- hydronephrosis (Left) in LD and MD group. Since these visceral abnormalities observed in treated groups were infrequencies comparable or even less in numbers to controls, therefore no toxicological significance can be attributed to these findings and considered to be spontaneous in nature.

Applicant's summary and conclusion
- Conclusions:
- In conclusion, the repeated dose administration of test material to pregnant female Wistar rats at dosages of 160, 400 and 1000 mg/kg body weight from gestation day 5 to 19 revealed no major toxicological findings in females and fetuses.
Based on the data generated from this study, The NOAEL for both maternal toxicity and fetal toxicity of test material in wistar rats was 1000 mg/kg body weight. - Executive summary:
This prenatal developmental toxicity study of test material was conducted in pregnant female wistar rats to detect the possible adverse effect on pregnant females and embryofetal development when administered by oral gavage from gestation day 5 to 19. Nulliparous and non pregnant females were mated with males (2:1 ratio) and divided into four groups based on their body weights on the day of sperm positive vaginal smears (GD 0). Four groups of presumed pregnant females were dosed daily by oral gavage with 0, 160, 400 and 1000 mg/kg bw per day of test material at dose volume of 10 mL/kg body weight. Control animals were handled identically as treated groups and received sterile water as a vehicle in similar volume as treated groups.
The test item formulation was prepared freshly and dose volumes were adjusted based on the most recent body weight measurement.
Animals were examined daily for the clinical signs and mortality. Body weight and food consumption was measured on various gestation days.
The treated and control females were sacrificed on respective gestation day 20. Followed by the gross necropsy evaluation of the females, the uteri and ovaries were removed, weighed and examined for number of implantations, resorptions (early and late) live and dead fetuses. Fetuses were identified by color strings, sexed and weighed. All fetuses were observed for external abnormalities, half of the fetuses for the visceral abnoramlities, craniofacial examination and remaing half of the litter for skeletal abnormalities.
Uteri of the non pregnant females were processed with 10% ammonium sulphide solution and checked for the early embryonic deaths if any.
No test item related clinical observations were observed in any of the dose group females during the entire period of the treatment when compared with controls. Two animals (51 and 73) from MD and 1 animal (94) from HD were died during the treatment period due to gavaging error.
Body weight, body weight change and food consumption remained unaffected throughout the treatment period.
Statistical analysis of prenatal data revealed no significant effect on prenatal parameters like terminal body weight, gravid uterus weight, adjusted maternal weight, number of corpora lutea, implantations, live fetuses, dead fetuses, resorptions, percent preimplantation loss and post implantation loss in the treated groups when compared with controls. However, statistically significant increase in group mean number of male fetuses in MD and HD group and sex ratio in HD group was observed when compared with controls. Group mean number of females was decreased in MD and HD group withought reaching statistical significance.
Statistically significant increase in group litter mean weight and male litter weight was observed in MD and HD when compared with controls. There was also decrease in female litter weight observed in HD when compared with controls. Group mean number of males was increased in MD and HD and group mean number of females was decreased in MD and HD as compared to controls. Total number of fetuses remained unaffected in treated groups when compared with controls.
Decrease in pregnancy rate was observed in control group (73.08%), LD (80.00%), and MD (80.77%) as compared to HD (92.00%).
Few gross external abnormalities were seen among the control and treatment groups.
Skeletal examination of the Alizarin red stained fetuses revealed a range of abnormalities which were of a type or which occurred at an incidence comparable in treated groups when compared with controls. Statistically significant increase in incidence of incomplete ossification of 5th and 6th sternebra and significant decrease in incidences of ansent 4th metacarpal (bilateral) was observed in LD and HD resepectively.
Internal observation of the fetal viscera by free hand microdissection technique revealed a range of visceral abnormalities in all groups including control. There was statistically significant decrease in kidney- hydronephrosis (Left) in LD and MD group.
Craniofacial examination by razor blade serial sectioning technique revealed a range of visceral abnormalities in all groups including controls.
The terminally sacrificed animals belonging to the control and treatment groups revealed lesions like kidney cyst, pale kidneys, lung with white spots. There was increased number of incidences of blue/green discolouration of various visceral organs observed in treated groups. All these effects were not related to substance toxicity.
In conclusion, the repeated dose administration of test material to pregnant female Wistar rats at dosages of 160, 400 and 1000 mg/kg bw from gestation day 5 to 19 revealed no major toxicological findings in females and fetuses. Based on the data generated from this study, The NOAEL for both maternal toxicity and fetal toxicity of test material in wistar rats was 1000 mg/kg bw.
