Forced Degradation

Forced Degradation describes deliberate exposure of drug substances or drug products to stress conditions such as heat, light, oxidation, acid or base hydrolysis, and mechanical stress to accelerate degradation pathways. This approach identifies potential degradation products, supports development of stability-indicating analytical methods, and informs formulation and packaging decisions.

The pharmaceutical industry performs forced degradation as standard practice in method development and stability programme design. Results help establish impurity profiles, define acceptable limits, and ensure analytical methods can detect changes relevant to product quality. Regulatory agencies expect forced degradation evidence supporting stability-indicating methods used for release and shelf-life testing. Biologics require additional evaluation of aggregation, fragmentation, and post-translational modification changes under stress. As regulatory scrutiny increases and product complexity grows, forced degradation remains essential for demonstrating robust stability control strategies.
