What is PDE? Permitted daily exposure
What is PDE?
Permitted daily exposure (PDE) is a term used in the pharmaceutical industry to describe the maximum amount of a substance that can be consumed daily without causing harm. It is an important concept in drug development as exposure to certain substances, even at low levels, can have harmful effects on the body.
How does it work?
The PDE is determined through a rigorous process of risk assessment and toxicology testing. It takes into account various factors such as the mode of action of the substance, the potential for accumulation in the body, and the sensitivity of certain populations to its effects.
Once the PDE has been established, it is used to set limits on the amount of the substance that can be present in a drug product, as well as the maximum daily dose that can be administered to patients. This helps to ensure that patients receive a safe and effective treatment with minimal risk of adverse effects.
It is important to note that the PDE is not a static number and can change over time as new scientific information becomes available. Manufacturers are required to monitor and update their PDE values as necessary to ensure that their products remain safe for consumption.
In addition to pharmaceuticals, PDE values are also used in the food and cosmetics industries to ensure the safety of products that are ingested or applied to the skin.
Conclusion
Overall, the concept of permitted daily exposure plays a critical role in ensuring the safety of products that are consumed or applied to the body. By carefully assessing and setting limits on the amount of a substance that can be safely consumed, manufacturers can provide effective treatments while minimizing the risk of harm to patients.
