Definition Of Mean Kinetic Temperature

Thermodynamic temperature is the measure of absolute temperature and is one of the principal parameters of thermodynamicsA thermodynamic temperature reading of zero denotes the point at which the fundamental physical property that imbues matter with a temperature transferable kinetic energy due to atomic motion begins. A mean kinetic temperature MKT should be obtained for any separate areas within the warehouse see Pharmaceutical Calculations in Prescription Compounding 1160 for samples of MKT calculations.

Definition of mean kinetic temperature. In science thermodynamic temperature is measured on the Kelvin. MKT is not a simple arithmetic mean but is calculated from the temperatures of stability chambers. This guidance addresses climatic zones I and II.

Consider the following example. A single derived temperature that if maintained over a defined period of time affords the same thermal challenge to a drug substance or drug product as would be experienced over a range of both higher and lower temperatures for an equivalent defined period. T K H R ln t 1 e H R T 1 t 2 e H R T 2 t n e H R T n t 1 t 2 t n displaystyle T_.

However the calculation can be difficult and is often misused. Mean Kinetic Temperature MKT is a simplified way of expressing the overall effect of temperature fluctuations during storage or transit of perishable goods. This temperature value is what the stored goods effectively feel during the mentioned time.

A dozen eggs sat. The MKT is widely used in the pharmaceutical industry. Mean kinetic temperature MKT is a simplified way of expressing the overall effect of temperature fluctuations during storage or transit of perishable goods.

Especially a function of the root mean square velocity of the molecules. The mean kinetic temperature in any part of the world can be derived from climatic data and the world can be divided into four climatic zones I-IV. The MKT is widely used in the pharmaceutical industry.

Mean Kinetic Temperature MKT Mean Kinetic Temperature MKT is used in the pharmaceutical industry to evaluate the effect of fluctuating temperature over time on the efficiency and safety of a biopharmaceutical product. Kinetic temperature Noun a measure of the energy of motion possessed by a substance. Stability tests can measure the acceptable temperature range of new and old products.

A temperature maintained between 20 and 25 C that results in a mean kinetic temperature MKT calculated not to be more than 25 C and that allows EXCURSIONS between 15 and 30 C United States Pharmacopoeia USP has described the different labelling terminologies related to temperature conditions. As per ICH guidelines Mean Kinetic Temperature can be defined as a single calculated temperature which degrades the same amount of the drug as degraded by the different temperatures during the particular time period. The mean kinetic temperature.

In a 20 C room for 2 hours In 2 C refrigeration for 4 hours. Mean kinetic temperature is a simplified way of expressing the overall effect of temperature fluctuations during storage or transit of perishable goods. In simple terms MKT is the value that indicates the effect of temperature variations over a period of time.

What is Mean Kinetic Temperature in basic language. Mean Kinetic Temperature is defined by the USP 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. WHAT IS MEAN KINETIC TEMPERATURE.

Mean Kinetic Temperature in GxP Environments. Guidance for Industry Stability Testing of Drug Substances and Drug Products This draft gives a much briefer definition. If you have a set of temperature readings across a certain period of time the Mean Kinetic Temperature across this period means effective average thermal value fo r this period.

The mean kinetic temperature can be expressed as. Mean Kinetic Temperature MKT is a calculation used in stability studies of pharmaceutical products. The MKT formula goes back to the Swedish scientist Svante August Arrhenius 1859 1927 who was born in Uppsala.

The result defines the products normal storage conditions and displayed on product labels. For another regulatory source that defines mean kinetic temperature refer also to the FDAs draft document. Mean Kinetic Temperature MKT is defined as the isothermal temperature that corresponds to the kinetic effects of a time-temperature distribution.

Once youve calculated the mean kinetic temperature you can determine if conditions are in a zone that is out of acceptable temperature and humidity ranges for your production processes. Mean Kinetic Temperature MKTThe single calcu-DISTRIBUTION PRACTICES FOR lated temperature at which the total amount of degrada-tion over a particular period is equal to the sum of the DRUG PRODUCTS individual degradations that would occur at various tem-peratures. Initially warehouse mapping needs to be repeated until you determine that the facility remediation steps taken have been successful in bringing mean kinetic temperatures into the acceptable range.

Definitions and Applications Vaisala In recent years mean kinetic temperature MKT has been identified as a potential tool for evaluating the impact of temperature on product quality.
