Vaisala offers comprehensive mapping qualification solutions to help you to comply with the GDP (Good Distribution Practice) regulations such as EU GDP (2013/C 343/01) and USP 36 Chapter <1079> and the forthcoming <1083>. Environmental mapping qualifications — necessary in areas that store human and investigational medicinal products — are performed by drug manufacturers, storage facilities, wholesale distributors and other stakeholders in the GxP supply chain. See a sample of Vaisala's IQOQ protocol (PDF).

Good Distribution Practices have seen increased regulatory focus in the past years. This was in large part initiated by the Canadian regulatory agency Health Canada (GUI-0069, 2011), which was the first regulatory body to mention temperature mapping. This direction was soon reiterated by regulatory bodies around the globe, including:
Each of these organizations has since published the new or updated guidelines and documents. The USA then updated USP Chapter <1079> “Good Distribution Practices for Drug Products”. Soon thereafter several guides emerged to offer specific instructions. For example, the International Society for Pharmaceutical Engineering’s cold chain management publication provides advice on the placement of mapping qualification sensors. The Parenteral Drug Association’s Technical Report 58 discusses how to perform risk assessments related to GDP. And the Pharmaceutical Inspection Co-operation Scheme released their own GDP guide, which aligns closely with EU GDP regulation. This was an important step towards global standardization as PIC/S currently has more than 40 participant countries.
Meanwhile, distribution activities have evolved, and distribution chains are increasingly international. However, this has resulted in an increased risk of temperature excursions. A well-executed environmental mapping qualification is the ideal method to assess and offset the risk of excursions. But, what constitutes a well-executed mapping qualification? First, studies should always be performed before any regulated medicinal products are allowed in a cold storage area, warehouse, and temperature controlled room or chambers. Mappings should be performed under representative conditions. In practice, this means seasonal mapping studies, winter and summer. In addition, mappings should include empty and loaded conditions. Once mapping qualifications have been performed for an area or chamber, the monitoring sensors are then placed according to the locations where the most temperature fluctuation occurred - often called hot and cold spots.
The ultimate goals of the environmental mapping qualification can be summarized like so:
It’s important to remember that mapping qualification studies are not restricted to fixed places. For temperature controlled vehicles in the distribution chain, the original temperature mapping qualification is performed according to the fundamentals outlined above: under representative conditions, loaded and unloaded, with areas either excluded as a storage location or monitored continuously according to the results of the study.
