Which in the name under which a drug is sold by a specific manufacturer?

Answer

The correct answer is: **brand name**. ### Explanation: In pharmacology and drug manufacturing, the term used for the name under which a drug is marketed and sold to consumers by a specific manufacturer is known as the "brand name". Each brand name is unique to the manufacturer and is how the drug is commonly recognized in the healthcare market by both professionals and patients. To clarify the other names: - **Chemical name** refers to the specific molecular structure of the compound of the drug. It’s generally long and complex. - **Generic name** is the common name for the drug, which can be used by any manufacturer and is not protected by trademark. - **Official name** is typically associated with the name listed in official pharmacopeias but may not necessarily denote how it is marketed by manufacturers. Therefore, the best choice for the name used by a specific manufacturer is the "brand name".
