Stability Study

Stability study is essential to deliver a high-quality pharmaceutical product. Stability study determines how a drug product will react when exposed to conditions such as heat, pH, humidity and radiation. Understanding how a drug product changes over time is critical to patient safety and is needed to guide the storage and disposal of the product. BOC Sciences is committed to providing comprehensive and cost-effective GMP stability testing, study management and stability storage services in accordance with cGMP and ICH guidelines

Our Services

To make it easier and better for researchers, BOC Sciences provides stability study service in a competitive fashion. We have provided a more efficient way to increase the number of new drugs, greatly shorten the R&D cycle, and reduce the development costs.

How is stability testing performed?

  • Data collection: to determine the most appropriate method for product stability and the stability of its packaging
  • Forced degradation studies: to determine the stability of a product over time
  • Stress testing: to identify possible degradation products, which in turn helps establish the intrinsic stability of degradation pathways and molecules, and verifies the stability indicating capability of the analytical procedures used
  • Studies are performed under at least two different storage conditions: long-term ambient storage and accelerated conditions. Each stability program is conducted according to an approved protocol, and testing includes the physical and chemical properties of the product that may change during storage, potentially affecting its strength, quality, purity, and ultimately, safety

How much of the products should be tested?

Typically, three validation batches of a product are placed under formal stability studies, and we recommend to perform informal studies of development batches prior to initiating formal studies, which is helpful in designing a better packaging configurations. In addition, batches produced for additional validation, such as process scale-ups, are often added to stability studies to demonstrate ongoing material stability
