WHO Stability Guidelines:

WHO has also formulated international regulatory standards on several quality related issues, which include stability, packaging, storage, and bioequivalence. Care must be taken to ensure that active pharmaceutical compounds remain stable and unaffected by packaging materials or storage conditions. Further, the establishment of bioequivalence standards between brand and generic drugs is of great importance given WHO’s support of generic products and their potential to increase access to essential drugs.
