‘How to’ – Stability Studies

Accelerated stability testing is a crucial aspect of the pharmaceutical development process, allowing manufacturers to estimate the shelf life of drug products in a relatively short period. This type of testing is important because it helps ensure that the drug products remain safe and effective throughout their intended shelf life. Accelerated stability studies are particularly relevant when fast-tracking drug approvals, enabling pharmaceutical companies to meet regulatory requirements without the long waiting periods associated with real-time stability studies. The process also provides valuable data that can be used to predict the behavior of drug products under normal storage conditions. In this guide, we will walk you through the step-by-step process of conducting accelerated stability testing, referencing the relevant guidelines from regulatory authorities.
