All the study proceeded in SPF (Specified Pathogen Free) animal house of CETA in SPF conditions according to internal SOP No. 46
Animals were housed in SPF animal room, 2 rats of the same sex in one plastic cage (40x25x20 cm) containing sterilised clean shavings of soft wood.
Housing conditions
Animals were housed in controlled environment, in which optimal conditions were considered to be approximately 15 air changes per hour, a temperature of 22+3°C, a relative humidity of 30-70% and 12-hour light/12-hour dark cycle (according to internal SOP No. 46).
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- water
- Details on oral exposure:
- The application form was prepared by mixing with aqua pro injectione. Two concentrations of application form were prepared (50 mg/10 mL and 1000 mg/10 mL).
The test substance was administered to the stomach by gavage as the solution in aqua pro injectione. Oral way of administration was chosen according to the guideline and it was approved by sponsor. The animals were treated 7 days per week at the same time (8.00 – 10.00 am).
The concentrations of solutions at all dose levels were adjusted to ensure the administration of 1 mL per 100 g of body weight. The vehicle control group was administered by aqua pro injectione in the same volume. The application form (test substance solution in aqua pro injectione) was prepared daily just before administration. - Analytical verification of doses or concentrations:
- yes
- Details on analytical verification of doses or concentrations:
- Stability and homogeneity of the substance were determined by evaluation of absorbance measured at maximum of the test substance absorbance spectra by spectrophotometric method.
- Duration of treatment / exposure:
- Males were exposed for 28 days, i.e. 2 weeks prior to mating, during mating, and up to termination. Females were exposed for
41-54 days, i.e. during 2 weeks prior to mating, during mating, during post-coitum, and during at least 5 days of lactation. - Frequency of treatment:
- The animals were treated 7 days per week at the same time (8.00 – 10.00 am).

Note:Only organs demonstrating treatment-related changes and reproduction organs: stomach, vagina, ovary, uterus and pituitary gland in females and organs with macroscopical changes were examined at the lowest and middle dose level groups.
Applicant's summary and conclusion
- Conclusions:
- Based on the results of a Combined Repeat Dose Toxicity Study with Reproductive/Developmental Screening (OECD 422), the NOAEL for repeated dose toxicity was established as 240 mg/kg body weight/day for males and females based on histopathological changes to the forestomach (local irritative effect) at 720 mg/kg bw.
The value of NOEL was established as lower than 80 mg/kg body weight/day. According to Regulation EC No. 1272/2008 and Directive 67/548/EEC, the test substance does not require classification on the basis of the results achieved in this study. - Executive summary:
In a Combined Repeat Dose Toxicity Study with Reproductive/Developmental Screening (OECD 422), three groups of 24 Wistar rats (12 males, 12 Females) were exposed to test substance by oral gavage at dose levels of: 80, 240 and 720 mg/kg b.w.
A vehicle control group was included. Satellite groups of 6 males and 6 females contained one control group (vehicle only) and one treated group (720 mg/kg/day).The dose levels for the study were determined on the basis of results of a dose-range finding study phase.
Males were exposed for 28 days, i.e. 2 weeks prior to mating, during mating, and up to termination. Females were exposed for 41-54 days, i.e. during 2 weeks prior to mating, during mating, during post-coitum, and during at least 5 days of lactation.Clinical signs, functional observations, body weights, food consumption, reproduction parameters, observations pups, clinical pathology, macroscopy, organ weights, and histopathology were evaluated.
Repeated oral administration of the test substance at the dose level 720 mg/kg/day caused mortality (one female of the highest dose level died during pregnancy period).
Slight changes of body weight and body weight increment in males, clinical status of animals (diarrhoea or dyspnoea), biochemical parameter (significantly increased value of albumin in females), urinalysis in males (significantly decreased urine volume), and microscopical structure of organs (prostate gland in males and uterus and mammary gland in females) were detected at the dose level 80 mg/kg/day. These microscopical changes in reproductive organs did not relate to the test substance treatment.
Slight changes of body weight, body weight increment, food conversion and clinical status (diarrhoea, salivation) of animals were detected at the middle dose level. Haematological parameters (significantly decreased value of protrombin time in females), biochemical parameters (insignificantly decreased albumin in males but under historical control limits) and urinalysis in males (significant decrease of urine volume, significant increase pH of urine, presence of protein and leucocytes) showed treatment-related changes.
Occurrence of microscopical changes of epididymis and testes in males and mammary gland and uterus in females were detected at the dose level 240 mg/kg/day, however these changes were consodered not rleated to treatment.
Slight changes of body weight, body weight increment and food conversion of animals were detected at the highest dose level. The clinical status of animals after application was influenced by the test substance treatment (salivation and/or chemical odour around animals and/or dyspnoea).
Changes in haematological parameters (delayed significantly increased value of platelet count and delayed significantly decreased value of APTT in males and delayed significantly decreased value of APTT, delayed significantly increased value of RBC, haematocrit, haemoglobin and platelet count in females) and blood biochemical parameters (significantly decreased value of glucose, potassium ions and activity of ALT, delayed significantly increased value of inorganic phosphorus ans insignificantly decreased value of albumin in males and delayed significantly decreased activity of AST, delayed significantly increased value of calcium ions, protein total and albumin in females, changes of albumin in both sexes were out historical control limits), urinalysis (significant decrease of urine volume, significant increase pH of urine and change of colour, presence of protein, urobilinogen, ketones and leucocytes), biometry of organs (delayed significantly increased absolute weight of pituitary gland and significantly increased relative weight of pituitary gland in males, delayed significantly decreased relative weight of liver, kidneys and thymus in females) were detected.
Occurrence of macroscopical changes (mainly in forestomach in males and females) and microscopical changes (mainly in forestomach, prostate gland and epididymis in males and forestomach, mammary gland and uterus in females) were detected at the dose level 720 mg/kg/day. Pathological changes in forestomach ((occurrence of inflammation and/or erosion and/or oedema) can be considered as attributable to the test substance administration. Also, influence of the test substance on growth of animals and clinical status of animals was observed (salivation, dyspnoea, chemical odour around animals, coughing).
Changes of haematological parameters (delayed changes of haemocoagulation parameters in males and red blood component and haemocoagulation parameters in females), biochemical parameters (changes of glucose, protein total, albumin, potassium and calcium ions, inorganic phosphorus, and ALT and AST activity), biometry of organs (changes weight of pituitary gland in males and liver, kidneys, thymus in females) and urine parameters in males (urine volume, pH of urine, colour, specific weight, occurrence of leucocytes, protein, urobilinogen and ketones) were detected at the highest dose level.
The value of NOAEL (No Observed Adverse Effect Level) for repeated dose toxicity was established as 240 mg/kg body weight/day for males and females.The value was established on the basis of histopathological results in the stomach. The test substance elicited local toxicity effect on the forestomach at 720 mg/kg bw.
