Disinfectants must be qualified on the surfaces in a pharmacopeial manufacturing environment prior to use in the facility. Building a study with robust parameters and avoiding common pitfalls is critical to avoid negative responses from regulatory agencies. Spending more time on study design and development upfront will save valuable resources in the long run.

The goal of this presentation is to provide a general overview of disinfectant efficacy testing and to provide a detailed methodology to assist in designing coupon studies that accurately represent facility procedures. As we attempt to bridge the gap between laboratory conditions and environmental conditions, test method acceptance criteria and interpretation of coupon study results will also be discussed. Specifically, we aim to provide insight into how the results of a coupon study can be utilized to improve cleaning procedures.

What you’ll learn if you attend:

  • Study Design – how to choose parameters that are representative of your facility while meeting regulatory expectations.
  • Indications that initial or subsequent disinfectant efficacy testing needs to be performed.
  • Interpretation of results – translating microorganism log reductions into useful information on the efficacy of facility cleaning procedures and disinfectants.
