Mechanochemical Degradation of Active Pharmaceutical Ingredients (APIs): A Simple Tool for the Prediction of Drug Stability

Year: 2025

Type: article

Abstract: Knowledge of the potential degradation products of active pharmaceutical ingredients (APIs) is of major interest for the development and approval of new drugs. Therefore, methodologies for the time-efficient and precise prediction of degradation products and pathways are of great importance. Traditional degradation assessments typically involve solution-based forced degradations under acidic, basic, thermal, or photolytic conditions. However, such conditions often fail to accurately replicate degradation pathways relevant to solid-state formulations. A promising addition to the established solvent-based approaches are forced degradation processes in the solid-state using mechanochemistry. The newly developed methodologies enable a time-efficient and accurate simulation of degradation pathways under mild reaction conditions in the solid-state. Herein, the general principles of forced mechanochemical degradations will be discussed on the basis of published case studies involving marketed drugs.
