Definition
pharmaceutical product related impurity role held by a material entity that differs from the targeted drug substance or drug product as a result of chemical change occurring during manufacture or storage
Explanatory Notes
Chemical change may be caused by light, temperature, pH, water, oxygen, process conditions, storage conditions, or reaction with an excipient or the immediate container closure system. Degradation product impurity role is used for product-related material that arises through degradation of the targeted drug substance or drug product, rather than through adventitious introduction or carryover of process materials.
Examples
- the degradation product impurity role of oxidized protein species formed during storage; the degradation product impurity role of deamidated protein variants formed under formulation pH conditions; the degradation product impurity role of hydrolyzed drug substance material formed during storage;
