Introduction of Stability Testing

Stability testing in drug development aim to provide evidence on how the quality of a drug substance or product and its packaging varies with time under the influence of various environmental factors, including temperature, humidity, and light. Any microbiological, physical, and chemical changes that may affect the efficiency and integrity of the final product need to be evaluated to ensure safety and effectiveness. Stability testing also establish the re-test period for drug substances, as well as the shelf life and recommended storage conditions for pharmaceutical products.

Stability testing is a complex set of procedures. The most suitable approach to gathering data is to conduct real-time stability testing. It is usually necessary to study under at least two different storage conditions: long-term and accelerated conditions. For long-term studies, the frequency of test points should be sufficient to establish the stability profile of the drug substance. At the accelerated storage conditions, a minimum of three time points, including the initial and final time points (e.g., 0, 3, and 6 months), are recommended. Prior to the approval of new products, it has become a legal requirement to provide data the regulatory agencies with certain types of stability test data.
