Ttc-based acceptable intake
WebCompound-specific risk assessments to derive acceptable intakes should be applied instead of the TTC-based acceptable intakes where sufficient carcinogenicity data exist. For a known mutagenic carcinogen, a compound-specific acceptable intake can be calculated based on carcinogenic potency and linear extrapolation as a default approach. WebA TTC value of 1.5 µg/day intake of a genotoxic impurity is considered to be associated …

WebJun 5, 2024 · Both PDEs are higher than the acceptable daily intake values (96 ng for NDMA and 26.5 ng for NDEA) calculated by regulatory authorities using simple linear extrapolation from carcinogenicity data. These PDE calculations using a bench-mark approach provide a more robust assessment of exposure limits compared with simple linear extrapolations … WebThe TTC-based acceptable intake of 1.5 μg/day is considered to be protective for a lifetime of daily exposure. To address less-than-lifetime exposure to mutagenic impuri-ties in pharmaceuticals, an approach is applied in which the acceptable cumulative lifetime dose …
