Final answer:
The official name given to a new drug developed by a company is called the brand name, whereas the generic name refers to the drug's active ingredient name.
Step-by-step explanation:
When a company develops a new drug and assigns it an official name, this name is known as the brand name. The generic name is the standard name for the drug's active ingredient, which is different from the brand name given by the original manufacturer. Generic drugs are often released after the patent on a brand-name drug expires, and they must be shown to be interchangeable with or therapeutically equivalent to the brand-name drug, as determined by the U.S. Food and Drug Administration (FDA) via an Abbreviated New Drug Application (ANDA).
