Applicant's summary and conclusion
- Executive summary:
The single oral administration of the test substance (ZK 233744) to male and female rats at a dose of 2000 mg/kg was tolerated without any mortality. No compound-related clinical signs or effects on body weight were observed and there were no macroscopic pathological signs.
The acute oral toxicity of Diketon in rats is therefore above 2000 mg/kg body weight.
