"Xinkang": trade name
"Isosorbide mononitrate": generic name. Note: The dispersible tablets here are pharmaceutical dosage forms. (I will discuss the dosage form of drugs in the future, so I won't discuss it here. )
Generic names of drugs: international non-patented names, which refer to names that can be used all over the world.
A trade name is a product name determined by a pharmaceutical manufacturer and approved by the pharmaceutical supervisory and administrative department. It is proprietary and cannot be copied. Under a common name, there may be multiple commodity names due to different manufacturers.
For example, in the above example, "metformin hydrochloride" is a common name; Moreover, manufacturers will choose a trade name according to their own needs-"Gehuazhi" or "Booker".
Analogy has never been an accurate rhetorical device, but this does not prevent us from using analogy to make a problem easier to understand.
We may drink milk every day, but what we often ignore is "milk". On the contrary, it will be easier to remember Sanyuan, Mengniu, Yili, Anjia, Deya and so on.
Trade names are meant to be easy to remember and spread, but in essence they may be just for selling more. However, as consumers or patients, it is still necessary to know the generic names of the drugs they take, otherwise mistaking "milk" for "coke" may bring them great trouble.
