Article 58 of Regulation (EC) No 726/2004 establishes a mechanism whereby the European Medicines Agency (EMA) may give a scientific opinion, in the context of cooperation with the World Health Organisation (WHO), for the evaluation of certain medicinal products for human use intended exclusively for markets outside the …

What is health-based exposure limit?

The health-based exposure limit for a given API is the permitted daily exposure (PDE) value (also known as the allowable daily exposure, or ADE). …

What are PDE values?

The Permitted Daily Exposure (PDE) values had been defined by the EMA in a new guideline in order to mathematically decide upon the dedicated or multi-purpose use of plants. The new health-based values influence the cleaning validation threshold values as well.

Who permitted daily exposure?

In the EMA’s HBEL guideline, the term permitted daily exposure was defined as follows: “The PDE represents a substance-specific dose that is unlikely to cause an adverse effect if an individual is exposed at or below this dose every day for a lifetime.”

What is acceptable daily exposure?

The health-based limit developed in the Risk MaPP Baseline Guide is referred to as an acceptable daily exposure or ADE. It represents a dose that is unlikely to cause an adverse effect if an individual is exposed, by any route, at or below this dose every day over a lifetime (ISPE, 2010).

How is PDE value calculated?

The PDE calculation involves steps like hazard identification through structured and strategized literature search, identification of critical effects, establishment of NOEL/NOAEL for critical effects and application of adjustment factors including bioavailability correction factors for a route to route extrapolation …

How do you calculate acceptable daily exposure?

ADEs are calculated in a similar manner using the following formula: ADE = (NOAEL x BW) / (UFC x MF x PK) where: BW = Body Weight (kg) [default for an adult is 50 kg]; UFC = Composite Uncertainty Factor; MF = Modifying Factor; and PK = Pharmacokinetic Adjustment(s).
