Additional information

In a 6 or 7-day oral gavage study, plasma steady state concentration appeared to have been reached by day 4 for both male and female rats. There was evidence that the test substance preferentially partitioned into the liver in both male and female rats. A second toxicokinetic study in male and female rats via single oral gavage or i.v. injection revealed that the terminal elimination half-life ranged from 28-38 hours in males and 21-38 hours in females. Bioavailability of the test substance decreased as the dose increased indicating saturation in absorption. The test substance did not accumulate in females, but did accumulate to a small degree in male rats following 14-day repeated oral gavage.
