Applicant's summary and conclusion
- Conclusions:
- The fetotoxicity LOEL (Lowest observed effect level) of phthalylsulfathiazole in Rattus norvegicus by oral exposure was observed at a dose concentration of 441.9496 mg/kg/day .
- Executive summary:
The fetotoxicity LOEL (Lowest observed effect level) of phthalylsulfathiazole in Rattus norvegicus by oral exposure was observed at a dose concentration of 441.9496 mg/kg/day . This indicates that phthalylsulfathiazole shall not exhibit toxic effect to Rattus norvegicus by the oral route below the above mention dose.
