Determining TD50 values for Nitrosamine to establish higher Acceptable Intake

Discover our cutting-edge service designed for pharmaceutical manufacturing companies to determine the carcinogenicity of nitrosamines through TD50 assessment. Our computational approach aligns with EMA and FDA guidelines, ensuring your products meet regulatory standards and safeguard public health.

What is TD50?

TD50 represents the dose level necessary to cause cancer in 50% of animals (typically rats) exposed under experimental conditions. It’s crucial for evaluating the carcinogenic potential of genotoxic compounds like Nitrosamines in both animals and humans.

Guidelines on TD50

The FDA and EMA stipulate that the Acceptable Intake (AI) limits for highly genotoxic impurities, such as Nitrosamines, should be grounded on TD50 values. This approach is endorsed by major health authorities, including those in the US, Europe, and Canada, to ensure consumer safety.

Benefits of TD50 Assessment

  • Determines acceptable intake: Tailor AI of Nitrosamines to specific assessments rather than general limits, potentially allowing higher safe intake levels.
  • Regulatory compliance: Ensures products meet the stringent guidelines set by regulatory bodies.
  • Risk mitigation: Minimizes the risk of batch failures due to exceeding the general limit of genotoxic impurities.

Why Perform a TD50 Assessment?

Conducting a TD50 Assessment is essential for deriving safe intake levels of Nitrosamines, ensuring product safety, and maintaining regulatory compliance. It’s a proactive measure against the potential health risks associated with genotoxic impurities.

We utilize sophisticated software for surrogate analysis to perform comprehensive TD50 assessments. This method is recognized and accepted by regulatory authorities, providing you with a reliable basis for product safety decisions.
