Setting up a pharmaceutical cleaning strategy

Cleaning is an essential practice for any pharmaceutical activity. Difficulties can arise from the fact that the concept of ‘clean’ is not easily defined or can be related to non-evident residues.

 

Defining differences between sterilization and cleaning treatments, for example, is important to understand in-depth the main problems and peculiarities when setting up a cleaning strategy.

 

The kinetics of ordinary sterilization processes are well understood: to sterilize means to destroy or inactivate microorganisms. In this perspective, we know the target and we can define it in terms of a number (CFU/unit) and resistance (D, z). Though the definition of sterile product/ item is probabilistic (PNSU – Probability of Non-Sterile Unit or SAL – Sterility Assurance Level), it is universally accepted.

 

On the other hand, for a cleaning process, the “enemy” is not defined and, in any case, can vary on a case-by-case basis: residue of previously processed product, diluents, solvents, lubricants, microorganisms, etc. There is no absolute definition of cleanliness. The kinetics of the cleaning procedure are unknown. Consequently, also the definition of “cleaning dose” to be provided is undetermined.

 

In these conditions, even regulatory bodies struggle. Essentially, they allow manufacturers considerable flexibility in establishing their own cleaning specifications. The FDA, for example, does not define methods describing how a cleaning process should be validated. FDA inspectors have to assess the rationale used to set the cleaning limits, making sure that their basis are scientifically justifiable and grounded on adequate knowledge of the materials involved.

This is the reason why Fedegari have published a new e-book: to discuss the main challenges on taking the right decisions while developing a cleaning strategy. New requirements have been faced by manufacturers, new targets have been fixed and the evidence that these are met is shown through successful case studies. Our aim was to highlight the best practices and existing solutions to support your decision-making.

This is certainly a multidisciplinary issue that involves various company areas: from “Regulations” to Engineering, from Quality Control lab to Production department. Fedegari have collected contributions of all these areas together in order develop a robust and repeatable cleaning process.

In their new E-book you will find:

  • Aspects Distinguishing a Cleaning Process
  • Steps for Setting Up a Cleaning Procedure
  • Case Study I: Removal of Bacterial Endotoxins
  • Case Study II: Application of a Washer Sterilizer
  • Case Study III: Soil Removal From Smart Plate
