Preclinical Animal Toxicity Studies Repeated Dose 28-Day Subacute Oral Toxicity Study of Oxy Powder® in Rats
Objectives: lessThan br / greaterThan 1) To assess the Sub-chronic toxicity of Oxy Powder® administered orally to rats for 28 days, lessThan br / greaterThan 2) To determine (i) Target organ toxicity (ii) "No observed effect level (NOEL)" (iii) Reversibility of signs of toxicity after lessThan br / greaterThan recovery period. lessThan br / greaterThan Background: lessThan br / greaterThan US FDA does not evaluate safety, efficacy and quality of dietary supplement ingredients or products. GHC decided to lessThan br / greaterThan study safety of Oxy Powder®, a dietary supplement used in Chronic Constipation and IBS. lessThan br / greaterThan Guidelines followed: lessThan br / greaterThan (a) OECD Guidelines No. 407, (b) WHO GCP Guidelines lessThan br / greaterThan (c) UCSF IACUC POLICY (d) Schedule "Y" in Drugs and Cosmetics Rules, (India). lessThan br / greaterThan Study Design and Controls: lessThan br / greaterThan 1) Rats of both sexes in controlled age and body weight were selected. lessThan br / greaterThan 2) Oxy Powder® was administered at 250, 500 and 1000 mg/kg body weight as aqueous suspensions along with a lessThan br / greaterThan blank lessThan br / greaterThan 3) The results were recorded on day 0, throughout the dosing period of 28 days and during recovery period of 14 days lessThan br / greaterThan End Points: lessThan br / greaterThan 1) Ophthalmoscopic examination on days 0+29, lessThan br / greaterThan 2) Haematological analysis, biochemical analysis and urine analysis on days 0+29+43. lessThan br / greaterThan 3) Organ weights, histopathological and gross pathological observations of sacrificed animals recorded after recovery lessThan br / greaterThan period. lessThan br / greaterThan Observations: lessThan br / greaterThan 1) No abnormalities attributable to the treatment with Oxy Powder® lessThan br / greaterThan 2) No target organ toxicity lessThan br / greaterThan 3) No reversibility of any signs of toxicity at the end of recovery period of 14 days. lessThan br / greaterThan Conclusion: NOEL of Oxy Powder® administered orally to Sprague Dawley rats for 28 days was found to be 1000 mg/kg body lessThan br / greaterThan weight for male and female animals.
