What term refers to the brand name under which a drug is sold?

• A. Generic Name
• B. Official Name
• C. Chemical Name
• D. Trade Name

Answer: (D)

The term describes the brand name under which a drug is sold is trade name. This is the trademarked name created by the manufacturer for marketing and labeling, and it can vary by product and country even when the active ingredient is the same. For example, acetaminophen is the generic/nonproprietary name, while Tylenol is a common trade name in the U.S. (and Panadol in other regions). The generic name stays constant across brands, explaining why clinicians often prescribe by the generic name to avoid brand confusion. The chemical name, in contrast, specifies the exact molecular structure, not how the drug is marketed.
