GDP cold-chain compliance
Storage conditions, qualification, monitoring, excursions and data integrity — the temperature-control expectations of EU GDP and WHO guidance in one sequence.
For: Responsible persons, QA and logistics teams at wholesalers, 3PLs and pharmacies.
- 01GDP / GMPTemperature control under EU GDP: what is expectedEU GDP requires premises and equipment that maintain storage conditions, initial mapping before use, calibrated monitoring equipment, alarms, and records that demonstrate control.2 min
- 02GDP / GMPStorage 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.2 min
- 03GDP / GMPWarehouse qualification under GDP: from URS to routine monitoringA 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.2 min
- 04GDP / GMPQualifying temperature-controlled vehicles and shipping containersTransport equipment is qualified like storage: define the conditions, map with calibrated loggers under worst-case ambient and load, and monitor every shipment.2 min
- 05MonitoringWhat a continuous temperature monitoring system must doCapture at an appropriate interval, alarm reliably, store data securely with an audit trail, and keep working through power and network failures.2 min
- 06MonitoringAlarm limits vs acceptance limits: setting them correctlyAcceptance limits come from the product; alarm limits sit inside them to give time to act; alert (warning) limits sit inside those. Uncertainty and delay decide the gaps.2 min
- 07MonitoringReviewing and retaining monitoring recordsA monitoring record nobody reviews is not a control. Define the review frequency, what the reviewer checks, how the review is recorded, and how long records are kept.2 min
- 08GDP / GMPHandling temperature excursions in storage and distributionAn excursion is a deviation: contain, record, assess product impact against stability data, decide, and learn. The record must show all five steps.2 min
- 09GDP / GMPMean kinetic temperature (MKT): what it is and when to use itMKT 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.2 min
- 10GDP / GMPDeviations and CAPA for environmental control failuresAn 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.2 min
- 11GDP / GMPData integrity for temperature records: ALCOA+ in practiceTemperature records are GxP records. Attributable, legible, contemporaneous, original, accurate — plus complete, consistent, enduring and available — is the checklist.2 min
