Acute Toxicity: oral
Administrative data
- Endpoint:
- acute toxicity: oral
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- An acute intravenous toxicity study is available and shows an LD50 of 45.2 mg / kg.
If we consider this same value for exposure by ingestion, our approach is greater since we consider that 100% of the substance ingested is found in the blood system (which is not the case since the average oral bioavailability is less than 50%).
Considering an LD50 of 45.2 mg / kg, the risk of ingestion is overestimated.
With a such result, the subtsnace is considered as toxic by oral route - Cat. 2.
