Based on the experience made in GDP inspections, the U.K. Medicines and Healthcare Products Regulatory Agency (MHRA) has published things to consider for the transportation, packing, temperature management, the use of third party couriers and returns of refrigerated medicinal products:
Packing of consignments and temperature management during transportation:
The decisions made on how to proceed should be based on risk evaluation according to ICH Q9. However the temperature should be controlled and monitored anytime with calibrated devices. All transportation arrangements "should be regarded as an extension of the storage activities and distributors are expected to treat each journey as unique with the length and complexity, as well as any seasonal variations, being considered when choosing the packing method and mode of distribution."
And what about the Mean Kinetic Temperature (MKT)? Here, MHRA clearly describes the agency's thinking:
"The application of Mean Kinetic Temperature (MKT) to temperature monitoring of wholesale products is only appropriate where an acceptable MKT value is provided by the MA holder for a specific product, and the recording of temperature can be confirmed to be consistent and complete from the moment of leaving the manufacturer's premises. In practice the application of MKT fails where a complete chain of temperature recording cannot be allocated to a specific consignment of a product. Attempts to apply MKT have been proposed by wholesalers as an alternative to having adequate temperature control within their warehouses as well as attempting to downgrade the impact of temperature excursions. The use of MKT in the wholesale environment without robust supporting information and methodology is therefore discouraged".
Third party couriers
Returns of refrigerated medicinal products
For other returns, paragraph 6.3 of the EU-GDP Guidelines should be considered.
