GDP / GMP
Temperature control and quality expectations in regulated storage and distribution.
Temperature control under EU GDP: what is expected
EU GDP requires premises that hold storage conditions, mapping before use, calibrated monitoring equipment, alarms, and records that demonstrate control.
EU GMP Annex 15: the qualification stages explained
Annex 15 sets URS, DQ, FAT/SAT, IQ, OQ and PQ as a sequence that builds evidence a system is fit for its intended use, with requalification after changes.
Handling temperature excursions in storage and distribution
An excursion is assessed against the product's stability data, not averaged away. Six hours at 12 °C in a 40-day cold-chain profile moves MKT by 0.08 °C.
Mean kinetic temperature (MKT): what it is and when to use it
MKT is not an average. It is the single temperature that would do the same cumulative chemical damage, which is why it sits above the arithmetic mean.
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 trigger for re-qualification.
Data integrity for temperature records: ALCOA+ in practice
Temperature records are GxP records. Attributable, legible, contemporaneous, original and accurate — plus complete, consistent, enduring and available.
Deviations and CAPA for environmental control failures
An excursion, a failed calibration or a failed mapping is a deviation. Classify it, investigate the root cause proportionately, and close it with action.
Storage condition labels explained: 2–8 °C, 15–25 °C, 'do not freeze'
Label storage conditions come from stability studies, and each phrase has a defined meaning that sets the limits for mapping, monitoring and excursions.
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 and change control.
Stability chamber qualification
ICH states the conditions a stability study must hold. Qualification shows your chamber holds them at every shelf position, not just at the control probe.
