Results and discussion

Effect levels
Key result
Sex:
male/female
Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Based on:
test mat.

Any other information on results incl. tables

LD50's were calculated to be >2000 mg/kg p.o.

This study was not definitive due to the lack of a complete battery of measurements, of control groups, and the small n/group.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
For ziprasidone hydrochloride monohydrate the rat LD50 is > 2000 mg/kg/bw.
Executive summary:

The acute toxicity of the substance was tested in Sprague-Dawley rats. As a results, the rat LD50 is > 2000 mg/kg/bw, so the substance is not classified for acute oral toxicity.
