GDP / GMP
Temperature control and quality expectations in regulated storage and distribution.
Temperature control under EU GDP: what is expected
EU GDP requires premises and equipment that maintain storage conditions, initial mapping before use, calibrated monitoring equipment, alarms, and records that demonstrate control.
EU GMP Annex 15: the qualification stages explained
Annex 15 describes URS, DQ, FAT/SAT, IQ, OQ and PQ as a sequence that builds evidence a system is fit for its intended use — with requalification when things change.
Handling temperature excursions in storage and distribution
An excursion is a deviation: contain, record, assess product impact against stability data, decide, and learn. The record must show all five steps.
Mean kinetic temperature (MKT): what it is and when to use it
MKT is a single temperature that represents the cumulative thermal stress of a varying temperature history, weighted by the Arrhenius relationship. It is useful for storage assessment, not for hiding excursions.
Qualifying temperature-controlled vehicles and shipping containers
Transport equipment is qualified like storage: define the conditions, map with calibrated loggers under worst-case ambient and load, and monitor every shipment.
Warehouse qualification under GDP: from URS to routine monitoring
A qualified warehouse has a documented requirement, a mapping study that meets it, monitoring placed by the results, and a change-control trigger for re-qualification.
Data integrity for temperature records: ALCOA+ in practice
Temperature records are GxP records. Attributable, legible, contemporaneous, original, accurate — plus complete, consistent, enduring and available — is the checklist.
Deviations and CAPA for environmental control failures
An excursion, a failed calibration or a mapping failure is a deviation. Classify it, investigate root cause proportionately, and close it with an action that prevents recurrence.
Storage condition labels explained: 2–8 °C, 15–25 °C, 'do not freeze'
Label storage conditions derive from stability studies under ICH conditions. Each phrase has a defined meaning that sets the limits for mapping, monitoring and excursion assessment.
Computerised system validation for monitoring and mapping software
Software that produces GxP records must be validated for its intended use: requirements, risk assessment, testing, audit trails, access control and change control.
