Regulatory Storage of Medical Drugs

casestudyMedicines are sensitive products. Having them stored at temperatures too low or too high can affect their overall quality, potentially making them less effective and even causing adverse effects during use. This means that correct storage conditions are not only essential to ensure medicine quality, they are also required by law.

Why monitor environmental conditions?

Medicine control and EU GDP Guidelines suggest that suitable equipment and procedures should be in place to monitor the environment where medicinal products are stored. Environmental factors to be considered include temperature, light, humidity, and cleanliness. For example, many medicines should be stored between +15°C and +25°C to ensure their quality is maintained. Other temperature-sensitive drugs, such as insulin or some antibiotic liquids must be kept in refrigerators between +2°C and +8°C. If medicines are not stored at correct temperatures they muse be destroyed, resulting in large, unnecessary, financial losses.

How Rotronic can help?

Rotronic has over 50 years’ experience in environmental monitoring to GxP guidelines. With “RMS” Rotronic can provide a monitoring system that was developed based on GAMP5 recommendations, in collaboration with multiple experienced pharmaceutical users to comply with several industry regulations, including FDA CFR 21 Part 11 and EU Annex 11.

RMS is an advanced, modular monitoring system with all data available securely via any device, anywhere. It can provide users with exactly the data they need, in the format they require, with extensive reporting and configurable alarms.

One of the key features of RMS is that not only can it be used with Rotronic hardware, but it can also be used with existing hardware from other manufacturers, as well as interact with other software / hardware platforms. RMS can be provided as a hosted cloud service or using a traditional license whereby the client installs the system on their own servers (local or cloud).

In summary RMS provides….

  • Live and interactive charts for all monitored parameters
  • Full alarm and alerts, easily configured
  • All data available with automated scheduled report generation
  • Complete event logging and compliance with GxP requirements
  • Email, phone, SMS, relay and custom protocol alarm notifications
  • Automatic data back filling and retrospective alarms (ideal for transportation logging)
  • Interactive, user configurable on-screen layouts

Alarming / Reporting

The alarm function in RMS ensures users are alerted whenever conditions stray outside their set limits. For example, if a refrigerator is broken, causing its internal temperature to rise above limits, an alert is triggered, notifying users, via email, SMS, or phone call, to act before medicines are damaged. The warning function can also be used to warn users whenever environmental conditions get close their critical limits, giving time to react before the critical limit is reached. Depending on individual requirements, a detailed alarm report can be automatically generated and sent to selected users via email.

RMS KITAutomated solution

The RMS Starter Kit for monitoring storage of medicines includes three wireless temperature loggers, a gateway (wireless receiver) and the corresponding software license. We have also included a service level agreement to help ensure a quick response to any questions that may arise.

Standalone solution

Data logger TL-1D or HL-1D Collage HL-1D.jpg
For a standalone solution, you can use our TL-1D temperature loggers or HL-1D humidity and temperature logger. These battery powered devices record environmental data which can be accessed by connecting the logger, via its USB port, to a PC running the free HW4-LITE software. These devices are not compatible with the RMS meaning data must be accessed manually. Once data has been downloaded, HW4 can be used to generate a detailed PDF report, which includes a graphical representation of the data, along with various statistics, and details of any period during which conditions where outside their alarm limits.

Rotronic ISO17025 Calibration



Rotronic instruments have a UKAS / ISO17025
accredited laboratory for the calibration of humidity, temperature and dew point instrumentation. We are proud to advise that we can offer some of the lowest measurement uncertainties of any commercial laboratory in northern Europe.

Why is Calibration important?

Calibration is the only way to prove instrument performance. By comparing an instrument against a known reference at several stable conditions we can asses what error exists. Over time we can assess the instruments drift and repeatability. Once errors are know they can be corrected for or adjusted out. ISO17025 calibration is performed with a laboratory that is regularly audited to ensure compliance to strict standards. All ISO17025 laboratories have defined measurement uncertainties and regularly perform inter-comparisons with other laboratories to ensure performance. Calibration is essential for compliance within many industries (FDA, GAMP, ISO 9001) and should be considered by anyone that wishes to make meaningful measurements. Instruments need not be calibrated over their    entire working range, only the range they are used at. For relative humidity it is best to calibrate at the working temperature or over a temperature range.

Evaluating Uncertainty 

Improving quality is the key to mitigating risks and reducing costs. However, measurement uncertainty is a parameter that is often overlooked. It is an important aspect of measurement that affects quality, costs, decisions and risks. Measurement uncertainty is a calculation that defines the range in which the “true value” is expected to lie. Measurement uncertainty is calculated by tabulating the known sources of error in terms of probability distribution. The final result is typically displayed as a value at 95% confidence. Uncertainly is a far better term to use vs accuracy, uncertainly includes details of the specific instrument and how it is used. The need for increased accuracy is not as important as the need for quality measurements and knowledge of measurement uncertainty

Calibration SerPicture1vices – Our comprehensive range of industry leading calibration services include:

  • Calibration of relative humidity measuring instruments using unsaturated salt solutions at 5,10,11,20,35,50,60,65,75,80 & 95%rh.
  • Calibration of dew point measuring instruments over the range -60°C dewpoint to 95°C dew point.
  • Calibration of relative humidity measuring instruments by comparison with a chilled mirror hygrometer and platinum resistances thermometers in the range 0°C to 95°C; 2%rh to 98%rh.
  • Temperature calibration of probes in air -60°C
    to 150°C
