Permitted Daily Exposure / Health Based Exposure Limits

Establish PDE Values

 

Experienced

Since 2015 IASON consulting has created more than 800 Permitted Daily Exposure (PDE) documents for potential cross contaminants or proposed levels of an elemental impurity (exceeding PDE, ICH Q3D Guideline). Therefore, we possess both the experience and the capacity to quickly and efficiently evaluate vast amounts of substances.

 

Adaptive

Your company has special needs towards PDE creation or requires a very specific template to be used? At IASON consulting, we work on any template you provide. Alternatively, you may choose to use ours — for free, of course.

 

Compliant

Our well networked consultants are always up-to-date with the latest regulatory requirements for PDE creation.

 

Health Based Exposure Limits (HBEL)

The PDE is the most common form of HBEL that inspectors encounter. When conducting an HBEL assessment, available data are interpreted and necessary uncertainty factors are applied via analysis by our experts. At IASON, our consultants with expertise in toxicology / pharmacology will summarise decisions, justification, and final HBEL value based on a comprehensive literature search. HBEL assessments are required for all active pharmaceutical ingredients and to ensure organisational and technical control measures for producing medicinal products in shared facilities. If control measures cannot adequately assure potential contamination, a dedicated facility may be needed. HBEL can also be used to justify carry over limits used in cleaning validation.

 

No Doubt

Identify and erase potential cross-contamination concerns on medicinal products produced in shared facilities.
