Which term denotes the marketing name assigned by drug manufacturers?

• A. Potency
• B. Efficacy
• C. Official name
• D. Trade name

Answer: (D)

The marketing name assigned by drug manufacturers is the trade name. A trade name, or brand name, is the commercially marketed name for a drug and is usually protected as a trademark. It can vary by company and country, even though the underlying generic or official name stays the same. Potency and efficacy describe how strong a drug is and how well it produces its effect, not what it’s called. For example, acetaminophen is the generic name, while Tylenol is a trade name used by a specific manufacturer. This distinction helps separate the product’s brand from its standardized chemical identity.
