Which of the following information is indicated by the NDC number?

The NDC (National Drug Code) number is a unique identifier used in the United States to describe specific pharmaceutical products. It serves multiple purposes in medication management, including identification of the drug's manufacturer.

The NDC is structured in a way that contains three segments: the first segment identifies the manufacturer, the second segment specifies the product (which includes the strength and dosage form), and the third segment indicates the package size. This systematic coding allows pharmacists, healthcare providers, and regulatory agencies to accurately identify and track medications within the market.

While the other options pertain to different aspects of medication or pharmacy operations—such as dosage recommendations, the type of medication, or the expiration date—they do not directly relate to the information conveyed by the NDC number. Instead, the NDC primarily emphasizes the connection between the drug product and its manufacturer, making it crucial for medication safety, inventory management, and compliance with federal regulations.
