Answer 1

An "A" rating by the FDA means that a generic drug is therapeutically equivalent and interchangeable with its brand-name counterpart.

Step-by-step explanation:

According to the U.S. Food and Drug Administration (FDA), in order to determine the therapeutic equivalence of a generic drug to its brand-name counterpart, one should look for an "A" rating in the FDA's Approved Drug Products with Therapeutic Equivalence Evaluations (also known as the Orange Book). An "A" rating means that the generic drug is considered bioequivalent and therapeutically equivalent to the reference listed drug, and therefore, interchangeable. In contrast, a "B" rating would indicate that there is known or potential bioequivalence problems, and the products are not considered to be therapeutically equivalent.
