Impurity Analysis & Identification in Pharmaceuticals

GMP Isolation & Characterization of Impurities

Drug development timelines can be extended and marketed drugs may need to be recalled due to the presence of impurities in pharmaceutical products. Impurity analysis is crucial, since impurities can impact the safety and efficacy of pharmaceuticals, and these unwanted chemicals remain with the drug formulation or active pharmaceutical ingredient (API). Impurities can result from the manufacturing process and/or storage and can be introduced from a variety of sources, such as unintended by-products of API and/or excipients degradation. Additionally, process impurities from API and excipients manufacturing may be present, and impurities can be introduced into the drug product from container-closure contact. According to International Council for Harmonisation (ICH) Q3A – Q3E guidance, there are five primary categories for impurities associated with pharmaceuticals: impurities in new drug substances, impurities in new drug products, residual solvents, elemental impurities, and extractables/leachables. Examples of impurity sources include starting materials, intermediates, degradation products, unintended by-products, interaction products, reagents, catalysts, ligands, heavy metals, residual metals, residual solvents, or process aids used during production.

Impurity analysis and characterization includes impurity identification, structure elucidation, and quantitative determination of impurities and degradation products in bulk materials and pharmaceutical formulations. Acceptable limits for impurities as well as recommendations for impurity testing are detailed in both ICH and FDA guidance, including USP <1086> Impurities in Drug Substances and Drug Products. Avomeen’s Ph.D.-led teams of scientists can isolate and characterize impurities in accordance with FDA and ICH guidelines and are adept at developing and validating methods for monitoring impurities in pharmaceutical drugs and raw materials.
