China's National Drug Administration stipulates that the chemical name and generic name of a drug are formulated by the National Pharmacopoeia and Drug Administration, but the product name is designated by the manufacturer. It is this latter rule that has created conditions for the rename and multiple names of many drugs. In China, there are more than 200 commonly used drugs with various names in recent years, of which 4 account for 20%, 5 account for 25%, 7 name for 15%, and 15% There are more than 10 names for some medicines, some have more than 20 names, and most have more than 40 names. All these medicines with multiple names are truly "changing soup without changing medicine", the basic content It's the same, just the packaging or individual ingredients are changed, and the effect is completely consistent. This text is intended to explain.
