Regulatory Feedback on Shelf-Life Assignments from Stability Data
The shelf life, or expiration date, indicates the period during which a drug product maintains its identity, strength, quality, and purity. It influences labeling, market authorization, and patient safety. Regulatory authorities scrutinize shelf-life justifications to ensure they are based on valid, scientifically sound, and compliant data.
