Answer:
Option 4, one generic name and many trade names
Explanation:
In pharmacology, medications typically have one recognizable generic name that healthcare workers, providers, insurers, and patients can use to efficiently and effectively communicate about certain drugs with minimal confusion and misunderstanding. The generic drug uses the same active ingredients as the brand name drug, with the only difference being within the inactive ingredients. These differences then berth the many trade names that the medication can be sold under.
One example is a common expectorant medication sold under the generic name guaifenesin. From this one generic name, different brands (or trade names) arise, such as Mucinex, Robitussin, Hytuss, Vicks Dayquil Mucus Control, and Organidin NR, each with varying inactive ingredients.
In short, a drug can have one generic name and many trade names, option 4.
One example that comes to mind of a medication having two generic names and many trade names is the nonopioid pain relief drug acetaminophen. In the United States, this medicine is commonly sold under the trade name Tylenol. In other countries however, this same medication is seen as paracetamol, under the brand name Panadol. This is seen as an exception to what is commonplace in pharmacology.
