Permissable Daily Exposure

Establish PDE Values



Over the last four years IASON consulting has created more than 700 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 process vast amounts of substances.



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.



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