Applicant's summary and conclusion
- Conclusions:
- The No Observed Adverse Effect Level (NOAEL) of the test chemical in the Sprague Dawley rat via oral route, over a period of 28 days was found to be 1000 mg/kg body weight in male and female animals.
- Executive summary:
In a repeated dose toxicity study, Sprague-Dawley male and female rats were treated with the test chemical in the concentration of 0, 250, 500 and 1000 mg/kg bw orally by gavage for 28 days. All the male and female animals from control and different dose groups up to 1000 mg/kg survived throughout the dosing period of 28 days and the recovery period of 14 days. Male and female animals from control and different dose groups exhibited normal body weight gain at the end of the dosing period of 28 days and the recovery period of 14 days. Feed intake of animals from control and different dose groups was found to be comparable throughout the dosing period of 28 days and the recovery period of 14 days. Ophthalmoscopic examination, conducted prior to and at the end of dosing period on animals from control and different dose groups did not reveal any abnormality. Test item coloured faeces were observed in male and female animals from different dose groups during the dosing period of 28 days and the recovery period of 14 days. Detailed clinical observations conducted at weekly interval (upto 6th week) did not reveal any abnormality in all male and female animals from control and different dose groups during the dosing period of 28 days and the recovery period of 14 days. Similarly, Towards the end of the exposure period in week 4, functional observation battery such as sensory reactivity to stimuli of different types (e.g. auditory, visual and proprioceptive stimuli) revealed no abnormalities attributable to the treatment. Grip strength and Motor activity values observed in male and female animals for control and different dose groups were comparable. At the end of the dosing period on day 29, no statistically significant changes in the values of various hematological parameters and at the end of the recovery period on day 43, statistically significant decrease in the values of Total RBC at 1000 mg/kg, male. In female animals conducted at the end of the dosing period on day 29, statistically significant decrease in the values of MCHC at 250 mg/kg, female and at the end of the recovery period on day 43, no statistically significant changes in the values of various parameters were observed. The decrease in the values of various parameters was marginal and within the normal biological and laboratory limits. In male and female animals conducted at the end of the dosing period on day 29, statistically significant increase in the values of Sodium at 500 mg/kg in male. In addition, statistically significant decrease was observed in the values of Glucose and Total Cholesterol at 500 mg/kg, Calcium at 250 mg/kg, 500 mg/kg and 1000 mg/kg in male and Blood Urea Nitrogen and Urea Nitrogen at 250 and 1000 mg/kg in female. At the end of the recovery period on day 43 (Reversal groups) statistically significant increase were observed in the values of Total Protein, Globulin, Creatinine and Triglycerides at 1000 mg/kg in male and Total Protein, Glucose, Albumin and Globulin at 1000 mg/kg in female. In addition, statistically significant decrease was observed in the values of Bile Acid at 1000 mg/kg in male rats. The increase/decrease in the values of various parameters was marginal and within the normal biological and laboratory limits. Urine analysis conducted during 4th and 6th week of dosing period (on day 26, 27 and 43) no abnormality was attributable to the treatment. In addition, at termination of dosing on day 29, male animals at 250 500 and 1000 mg/kg dose groups revealed increased relative weights of liver when compared with that of controls. In addition, increased relative weights of heart were observed in male animals at 500 mg/kg dose group as compared to controls. In male animals sacrificed on day 43 at 1000 mg/kg reversal group, was found to be comparable with that of controls. At termination of dosing on day 29, at 500 and 1000 mg/kg dose groups revealed increased relative weights of liver and sacrificed on day 43 from 1000 mg/kg reversal group, revealed decreased relative weights of kidneys, adrenals and ovaries in female when compared with that of controls. Although significant changes in the values of organ weight were observed in male and female animals from different dose groups, no related gross pathological and histopathological findings were seen, hence these findings were considered to be of no toxicological importance. Test item coloured perianal region externally and test item coloured stomach mucosa in male and female at 250, 500 and 1000 mg/kg dose groups. In male and female animals from control, control reversal and 1000 mg/kg reversal dose groups did not reveal any abnormality. Although significant gross pathological observations were noted in male and female animals from different dose groups, no related histopathological changes were observed. Histopathological examination did not reveal any abnormality attributable to the treatment. Therefore, No Observed Adverse Effect Level (NOAEL) of the test chemical in the Sprague Dawley rat via oral route, over a period of 28 days was found to be 1000 mg/kg body weight in male and female animals.
