A patient brings in a leaflet listing both the generic active ingredient and the brand name for the same tablet. The patient asks why two different manufacturers can sell the identical active ingredient under two different brand names. Which statement correctly explains this situation?
- AEach manufacturer must invent its own generic name, so the same active ingredient ends up with several generic names and one shared brand name.
- BThe active ingredient was given a different chemical formula by each manufacturer, which is the reason the brand names differ.
- CThe single generic name identifies the shared active ingredient, while each manufacturer applies its own proprietary brand name as a trademark. Correct
- DBrand names are only permitted after a drug loses its generic status, so a product cannot carry a brand name and a generic name together.
Why A is wrong: Tempting because multiple products exist, but it reverses reality: the generic name is shared while each manufacturer markets under its own brand name.
Why B is wrong: Wrong because an identical active ingredient has one chemical formula; differing brand names are a marketing matter, not a chemistry difference.
Why C is correct: Correct. One nonproprietary generic name covers the active ingredient for all makers, and each company can trademark a separate brand name for its product.
Why D is wrong: Plausible to someone confusing patents with names, but a product carries both a generic name and, if branded, a brand name simultaneously.
