The term that refers to the period during which a drug remains effective is known as shelf life. Shelf life indicates the time frame in which a medication can be expected to maintain its intended potency and effectiveness when stored under proper conditions. This encompasses factors like temperature, humidity, and light exposure, which can all impact how long a drug remains viable for use.

The expiration date indicates the specific date after which the manufacturer cannot guarantee the full potency and safety of a drug, but it does not necessarily reflect the entire effective period of the drug—only the point after which the manufacturer advises against use.

Potency duration is not a standard term used in pharmacology to describe the effectiveness of a drug over time. While it implies how long a drug maintains its strength, it does not capture the broader context of shelf life.

Stability period may imply the time a drug retains its chemical and physical characteristics, but it is not commonly used as a formal term to define the effective duration of a drug. Thus, shelf life is the most accurate term for describing the overall effective period of a drug.
