Niveauet uden observerede negative effekter (No observed adverse effect level, NOAEL) blev vurderet til at være mindre end 75 mg/ kg/ dag og er cirka 25 gange større end den humane, daglige eksponering baseret på AUC- eksponeringen.
The no observed adverse effect level (NOAEL) was considered to be less than 75 mg/kg/day, and is approximately 25-fold greater than the human daily exposure based on AUC exposure.
