In medication management, which term describes the examination for drug quality and expiration?

• A. Quality Assurance
• B. Shelf-Life Review
• C. Purity Inspection
• D. Stability Testing

Answer: (C)

In medication management, the examination that directly determines how a drug’s quality changes over time and helps establish its expiration date is stability testing. This process evaluates whether the product remains within specification for potency, purity, appearance, dissolution, and packaging integrity under defined storage conditions, across time points from real-time to accelerated aging. The goal is to confirm that the drug stays safe and effective up to the labeled expiry, so appropriate storage instructions and shelf life can be set. Purity inspection looks at impurity levels at a single point in time and doesn’t assess how quality evolves with time, while a shelf-life review is related but is not the formal process used to establish expiration through time-dependent quality changes.
