Why Temperature Monitoring Matters in the Pharmaceutical Industry
Here are the main reasons why temperature monitoring is crucial in the pharmaceutical industry:
1. Ensuring Product Integrity and Patient Safety
For temperature-sensitive medications and vaccines, deviations from a product’s recommended temperature range can compromise its chemical composition, stability, and efficacy. Temperature monitoring allows companies to identify shipments affected by temperature breaches, ensuring that the products reaching patients are safe and efficacious to use.
2. Complying with Regulatory Standards
Regulatory agencies, such as the FDA and EMA, have established guidelines and regulations for temperature control in the pharmaceutical industry. Adhering to these standards is crucial for pharmaceutical companies to ensure compliance and avoid regulatory penalties.
3. Supporting Regulatory Audits
A temperature monitoring solution should generate detailed temperature records that can be used to provide evidence of proper storage, handling, and transportation practices during regulatory audits. Regulations require that these records be accurate and unable to be manipulated.
4. Minimizing Financial Loss
Temperature excursions can result in significant financial losses and slowdowns for pharmaceutical companies. Temperature abused products may need to be discarded and replaced, leading to increased costs.
What Tools are Used for Monitoring the Cold Chain?
Monitoring the pharmaceutical cold chain requires the use of highly accurate temperature monitoring technologies. Here are three common types of solutions used in the industry:
Passive temperature monitors, such as the TempTale Ultra, are the most commonly used pharmaceutical temperature monitoring devices due to being compact, accurate, easy to understand, and cost-effective. Each individually calibrated TempTale Ultra measures and stores temperature readings at regular intervals during transportation. At delivery, this data can be reviewed to determine if the medicine can be accepted, then stored in a proper data management system.
Real-Time Temperature Monitors
Real-time temperature monitors continually report temperature and location data during the transportation of pharmaceuticals. By synchronizing their live data to the cloud, temperature issues while the product is still in transit, and interventions can be made to prevent having to discard the product. Sensitech offers the TempTale GEO Ultra, a cloud-enabled IoT temperature monitor designed for life sciences, which provides real-time temperature data, location tracking, and instant alerts.
Stationary Temperature Monitoring
Stationary temperature monitoring is used to continuously track and record temperature conditions in fixed locations used to store pharmaceutical products, such as warehouses, cold rooms, or refrigerators and freezers. A stationary monitoring solution for life sciences, like Sensitech’s ColdStream® Site, should put compliance and temperature control first, including an audit log of all system activities, qualified installation, and compliance with data storage regulations. Temperature data can be monitored remotely using a web browser, with programmable alarms and automated reports.
What are Pharmaceutical Temperature Monitoring Requirements?
Regulatory agencies, such as the FDA in the United States and the EMA in Europe, have established guidelines and requirements that pharmaceutical companies must comply with when storing or transporting pharmaceutical products. Some key pharmaceutical temperature monitoring requirements are below, but note that regulatory expectations may vary between regions.
Good Distribution Practices (GDP)
GDP guidelines outline standards for the distribution of pharmaceutical products to ensure their quality and integrity. These guidelines emphasize the need for companies to monitor temperature conditions during storage and transportation, with calibrated temperature monitoring devices and accurate temperature records.
Validation of Temperature Monitoring Systems
Regulatory authorities require pharmaceutical companies to test and document their temperature monitoring systems for accuracy and repeatability. This process is called validation, and it is designed to ensure the temperature data collected is reliable enough to accurately judge a drug’s condition at its destination.
Documentation and Data Integrity
Companies must maintain detailed temperature records, including recording intervals, time and temperature readings, alarm calculations, and any corrective actions taken. To ensure data integrity, measures must be in place to prevent unauthorized alteration of temperature data.
Thermal Mapping and Qualification
Thermal mapping (also referred to as temperature mapping) is the process of assessing the temperature distribution within storage areas, such as warehouses, refrigerators, and freezers. It identifies temperature variations and hotspots, making continuous temperature monitoring systems more accurate and allowing a facility to be qualified.
Temperature Sensitive Medications
Many medications require specific temperature conditions to preserve their stability and therapeutic properties. Here are three examples of temperature-sensitive medications:
Insulin, a vital hormone for individuals with diabetes, is sensitive to temperature variations. It must be stored and transported between 2 to 8°C (36 to 46°F). Exposure to excessive heat or freezing temperatures can lead to insulin degradation, rendering it less effective for managing blood glucose levels.
COVID-19 vaccines, such as the mRNA-based vaccines by Pfizer-BioNTech and Moderna, require strict temperature conditions to maintain their effectiveness in combatting the COVID-19 virus. The Pfizer-BioNTech vaccine, for example, initially required ultra-cold storage temperatures of around -70°C (-94°F) for long-term storage.
Cancer/oncology treatments often fall into the category of biologics, which are highly susceptible to temperature variations. Many oncology medications, even within clinical trials, are life-saving drugs and can be very costly. The proper handling, storage and transportation of these medications is critical for patients.
