What does the acronym "NDC" stand for?

The acronym "NDC" stands for National Drug Code. This is a unique, numerical identifier assigned to each medication approved by the U.S. Food and Drug Administration (FDA). The NDC is critical for identifying drugs and their packages in the pharmaceutical distribution system, facilitating the tracking and managing of medications from manufacturers to pharmacies and patients.

The National Drug Code consists of three segments: the labeler code (identifying the manufacturer or distributor), the product code (identifying the specific strength, dosage form, and formulation), and the package code (identifying the package size and type). This coding system plays a significant role in ensuring medication safety, aiding in inventory management, and supporting regulatory compliance within the pharmaceutical industry.

The other options do not accurately reflect the meaning of NDC. National Distribution Control, New Dosage Classification, and Non-Drowsy Classification do not have the established significance or recognition associated with the pharmaceutical field that the National Drug Code does, making "NDC" synonymous only with National Drug Code in the context of medication identification and regulation.
