www.jpsr.pharmainfo.inForced degradation studies are also known as stress testing, stress studies, stress decomposition studies, forced decomposition studies, etc. Forced degradation is a process that involves degradation of drug products and drug substances at conditions more severe than accelerated conditions and thus generates degradation products that can
Q 3 B (R2) Impurities in New Drug Products
www.ema.europa.euthe data is recommended. Degradation products should be designated by code number or by an appropriate descriptor, e.g., retention time. If a higher reporting threshold is proposed, it should be fully justified. All degradation products at a level greater than (>) the reporting threshold should be summed and reported as total degradation products.

www.uspnf.comThe degradation products in drug products can arise from drug substances or reaction products of the drug substance with the environment, with an excipient, or an immediate container–closure system. Biological and biotechnological products, fermentation
HOW TO APPROACH A FORCED DEGRADATION STUDY
www.sgs.comexamine for degradation products. Usual-ly 100% should be reached by adding assay value and levels of degradation products. If 100%-level is not achieved, efforts to account for the missing mass should be made e.g. response factors, formation of volatiles or retained impu-rities. Depending on method precision, a variation between 97 to 104 % can be
POLYVINYL ALCOHOL (PVA)
www.fao.org4.2 Possible impurities (including degradation products) Impurities resulting from the manufacturing process include sodium acetate, methanol and methyl acetate. Levels of sodium acetate, a reaction by-product, are monitored using the residue on ignition test. The residual methanol and methyl acetate are monitored during the manufacturing process.
