It is not possible to obtain a meaningful MKT value from daily readings of simple max / min thermometers as temperature fluctuation is not a linear function. Mean Kinetic Temperature Calculator Excel ‘Recommendations on the Control and Monitoring of Storage and Transportation Temperatures of Medicinal Products’ The Pharmaceutical Journal (vol 267) July 2001). It may be applied in situations where control is good but where occasional excursions may be encountered. According to Pharmacopeia definition the MKT 'is defined as the single calculated temperature at which the total amount of degradation over a particular period is equal to the sum of the individual degradations that would occur at various temperatures.'Īccording to MHRA: 'Mean Kinetic Temperature (MKT) should not be used to compensate for poor temperature control of storage (or transportation) facilities. The MKT is widely used in the pharmaceutical industry. Mean kinetic temperature is a simplified way of expressing the overall effect of temperature fluctuations during storage or transit of perishable goods. One very interesting Q&A refers to Mean Kinetic Temperature Calculations (MKT). Based on the experience the MHRA answers frequently asked questions. The British Medicines Authority MHRA is performing GMP and GDP Inspections on a risk based strategy. Than a deterministic kinetic calculation.

If the wholesale authorisation holder is able to provide the marketing authorisation holder with details of MKT that the product has been subjected to whilst in his care as well as the times and extent of the temperature deviation, this may assist the marketing authorisation holder in formulating his advice to the wholesale authorisation holder. In the event of a temperature deviation, the wholesale authorisation holder should seek advice from the marketing authorisation holder of the medicinal item in question. It is unlikely that the wholesale authorisation holder will have sufficient data in his possession to assess the potential impact on a specific product of these deviations. These two deviations can have differing effect of the product. Temperature deviations usually fall into one of two categories: A ‘spike’ deviation where local conditions vary in such a way as the temperature suddenly deviates from and quickly recovers to within the required range and a ‘plateau’ deviation where the temperature lays outside of the range for an extended time period prior to eventual recovery. It is noted that some data loggers and building management systems are capable of recording multiple temperature readings over a time period and some offer the function of calculating the MKT over a given time period. According to Pharmacopeia definition the MKT "is defined as the single calculated temperature at which the total amount of degradation over a particular period is equal to the sum of the individual degradations that would occur at various temperatures."Īccording to MHRA: "Mean Kinetic Temperature (MKT) should not be used to compensate for poor temperature control of storage (or transportation) facilities.
