- Executive summary:
The purpose of this study was to assess the acute oral toxicity of the test article, Pseudoiron, in the rat using the Fixed Dose Method. Since the results of the range finding study indicated that a dose level of 2000mg/kg produced no mortality, in the main study, the test article was administered at this dose level as a single oral dose to a group of 5 male and 5 female rats which had been fasted overnight. The animals were examined frequently on the day of dosing and daily thereafter for a further 14 days at the end of which, they were killed and subjected to necropsy. When the test article was administered in the main study at a dose level of 2000mg/kg no deaths occurred and there were no clinical signs of toxicity throughout the observation period. There was no adverse effect on body weight gain in animals of either sex. No abnormalities were detected in any animal at necropsy. Treatment with the test article, Pseudoiron, at a dose level of 2000mg/kg bodyweight produced no deaths or clinical signs of toxicity. The results of this study indicate that the maximum tolerated oral dose is greater than 2000mg/kg bodyweight.
