The requirements for conducting forced degradation studies are based on guidelines and recommendations of the International Council on Harmonisation (ICH) and national regulatory bodies like the FDA, EMA and ANVISA. Stability assessment is crucial for drug substance (DS) and drug product (DP), as impurities and degradation products may appear due to chemical breakdown leading to product failure. In-depth stability assessment including long-term (12 months) or accelerated (6 months) stability studies have impact on the current heavy time constraints of the drug development process and may increase the time to get the product to market. Therefore, beside data from forced degradation studies, complementing ...

Forced degradation conditions represent the exposure of a drug substance (DS) or drug product (DP) to stress conditions more severe than accelerated conditions which result in relevant degradation products. Well-designed and -applied forced degradation is a useful tool in predicting drug stability, which is an essential critical parameter and has an impact on purity, potency, and safety of the DP. For instance, changes in drug stability may result in a decrease of the active substance or the formation of toxic degradation products. Currently, several guidelines provide general recommendations and guidance on forced degradation studies, but none of the guidelines gives ...

The chemical stability of pharmaceutical molecules is a matter of great concern as it affects safety and efficacy of drug products (DP) on the one hand, and involves considerable cost, time consumption and competitiveness on the other. Stability testing evaluates the effect of intrinsic drug properties and environmental factors on the quality of a drug substance (DS) or a formulated DP, and is utilized to predict the shelf life, to determine proper storage conditions and to suggest labeling instructions. Meaningful product-expiration dates are obtained after thorough, scientifically designed studies using specific stability indicating assays and appropriate, validated analytical methods, thorough ...
