Which drug's active ingredient is known as a generic name?

Ibuprofen is indeed the correct answer as it is the generic name of the active ingredient commonly found in various over-the-counter and prescription medications. In the pharmaceutical industry, the generic name is the official, non-proprietary name given to a drug, which is universally recognized regardless of brand variations.

This means that medications containing ibuprofen may be sold under different brand names, such as Advil or Motrin, but they all refer to the same active ingredient. This distinction is important because it ensures consistency in prescribing and dispensing medications, as healthcare providers and patients can identify the same drug under its generic name.

In contrast, brand names like Tylenol or Advil are products that contain specific doses of their active ingredients but do not represent the generic name itself. Amoxicillin is another example where the name itself is recognized as a generic name, but in the context of the choices given, ibuprofen is often highlighted for its widespread use and recognition as the generic counterpart of various marketed medications.
