Pharmaceutical stability testing is an important part of developing and producing pharmaceutical products to understand how the quality of the medicine will change over time. It is important that the medicine meets the quality, safety and performance requirements throughout its shelf life. Stability testing provides scientific data to understand how temperature, humidity, light and storage conditions could effect the pharmaceutical product to establish appropriate storage conditions and expiry dates.
The stability testing process starts by analysing the physical, chemical and microbiological properties of the pharmaceutical product. Depending on the formulation of the product, parameters such as appearance, active content, degradation, dissolution, water content and microbial quality can be analysed. This helps to understand if the product still meets its defined specifications.
Environmental conditions are very important for pharmaceutical stability. Certain medicines can be affected by high heat, humidity and light conditions. Stability testing can be carried out to understand the effects of these conditions on the product. Stability testing is performed using defined conditions to understand how the product will behave over time. The conditions and timing will depend on the relevant regulations and product.
Accelerated stability testing is a common method to understand the effects of higher environmental conditions on the product. This can provide useful data to understand how the product may degrade and assist in making decisions on the product. Long term stability testing is also carried out under defined storage conditions to gather data to support the proposed shelf life.
Pharmaceutical products require the right packaging to protect them from any environmental exposure. Packaging such as blister packs, bottles, closures etc will be analysed to fit the product requirements. The integrity of the container closure system and the performance of the packaging can impact how well the product maintains quality.
Sometimes stability testing is required when large changes have been made to formulations, manufacturing processes, manufacturing locations and packaging. This should be tested using the relevant quality and regulatory processes.
Analytical testing is an important part of stability testing. Using the correct analytical techniques, equipment, skilled staff and controlled conditions will ensure the results are reliable. Techniques such as high performance liquid chromatography, dissolution, microbiology etc can be used depending on the product and quality requirements.
Stability testing requires detailed records to be kept. Stability protocols, samples, storage, testing schedule, analytical data and evaluation reports will be kept by the manufacturer. Accurate records will help ensure traceability and allow quality to review how the product has performed. The data can also be used to support regulatory submissions.
Technology can be used to make stability testing easier. Environmental conditions can be monitored automatically, digital lab systems, electronic data and advanced analytical equipment can be used to ensure accurate data is collected. This can help with managing the lab.
When choosing a manufacturer for your pharmaceutical product, having the capability to carry out stability testing is an important factor. Businesses should consider the lab set up, analytical capabilities, stability chambers, environmental monitoring, records and regulatory compliance. Having a stability management process can help improve product development.
