forceddegradation

Forced degradation, also known as stress testing or accelerated stability testing, is a process used in the pharmaceutical and chemical industries to deliberately break down a drug substance or product under various stress conditions. The goal is to identify potential degradation pathways, characterize the resulting degradation products, and establish the intrinsic stability of the material. This information is crucial for understanding how a drug might behave under less extreme, real-world storage conditions and throughout its intended shelf life.

Common stress conditions include exposure to heat, humidity, light (photodegradation), oxidation, and acid or base hydrolysis. By subjecting the drug to these exaggerated conditions, chemists can induce degradation at a faster rate than would occur naturally. This allows for the identification of key degradation products and the development of analytical methods, such as High-Performance Liquid Chromatography (HPLC), capable of detecting and quantifying these impurities.

The data obtained from forced degradation studies helps in selecting appropriate packaging materials, defining storage conditions, and establishing a preliminary shelf life. It also aids in developing stability-indicating analytical methods that can differentiate between the active drug and its degradation products, ensuring the quality and safety of the pharmaceutical product. Furthermore, understanding degradation pathways is essential for impurity profiling and can inform the synthesis and purification processes.
