1. FDA Drug Nomenclature and Access

The FDA recognizes three distinct names for every drug to ensure clarity in prescribing and safety in manufacturing.

Chemical Name: Describes the exact molecular structure (e.g., N-acetyl-p-aminophenol). This is primarily used by chemists and researchers.

Generic Name (Non-proprietary): The official name assigned by the USAN Council (e.g., acetaminophen). There is only one generic name for each drug.

Brand/Trade Name (Proprietary): The name under which the manufacturer markets the drug (e.g., Tylenol).
