Understanding potential degradation
Forced Degradation Studies

Forced Degradation Studies

Forced degradation is the process of subjecting drug compounds to extreme chemical and environmental conditions to determine product breakdown levels and preliminary degradation kinetics, and to identify potential degradation products. They are used to facilit ate the development of analytical methodology, to gain a better understanding of active pharmaceutical ingredient (API) and drug product (DP) stability, and to provide information about degradation pathways and degradation products. It is particularly useful when little information is available about potential degradation products. In addition to develop stability- indicating analytical methods, these studies also provide information about the degradation pathways and degradation products that could form during storage, transportation.

Forced degradation studies may help facilitate pharmaceutical development in areas such as formulation development, manufacturing, and packaging, in which knowledge of chemical behavior can be used to improve a drug product.

Forced degradation studies / Stress studies

Stress studies at Protagen Protein Services (PPS) will be performed according to ICH Q1A.

The aim of stress studies is to identify degradation products and resulting degradation pathways. Thereby, suitable analytical procedures can be developed and validated. Furthermore, studies under stress conditions may be useful in determining the effect of  accidental exposures to conditions other than those proposed (e.g. during transportation).

Stress studies are required throughout the entire development of biopharmaceuticals. We perform stress studies ideally prior to method validation to also be able to use the generated stress samples for method validation.

Forced degradation products can be generated by e.g. oxidation stress, pH stress, temperature stress, agitation stress or freeze / thaw stress.
