Which term refers to a name not trademarked and can be used by any manufacturer?

• A. Generic name
• B. Brand name
• C. Trade name
• D. Official name

Answer: (A)

Nonproprietary naming distinguishes a universal name that anyone can use from proprietary brand names. The generic name is the nontrademarked identifier for the active ingredient and is assigned by official bodies, so any manufacturer may use it on labels and in prescribing information. This consistency helps clinicians and responders recognize the drug regardless of the brand. Brand or trade names are trademarked marketing names owned by a company and can vary between products, so they aren’t shared across manufacturers. The official name often aligns with the generic name in regulatory contexts, reinforcing that universal, nonexclusive identifier.
