The differences are as follows:

1. Drugs with the same ingredients but different trade names must have the same generic name.

Because the common name of a drug is the legal name of the drug that is formulated by the Pharmacopoeia Committee in accordance with the "Principles for Naming Common Names of Drugs" and reported to the Ministry of Health for filing. It is a drug with the same ingredients or the same formula in China. The common name is mandatory and binding. Therefore, the generic name must be used on the labels, instructions or packaging of drugs that are put on the market. The naming should comply with the provisions of the "Principles for Naming Generic Drug Names" and cannot be used for trademark registration.

2. The generic names of drugs are the same, but the trade names of drugs can be different. ?

The trade name is a product name determined by the drug manufacturer itself and approved by the drug regulatory department. It is proprietary and cannot be copied. Under a common name, there can be multiple trade names due to different manufacturers. For example, the western medicine cefoperazone sodium, the common name is cefoperazone sodium, and the trade names can be cephalosporin, cephalosporin, cephalosporin, cephalosporin, cephalosporin, cephalosporin, cephalosporin sodium, cephalosporin, cephalosporin wait.

Extended information

A drug is often produced by multiple manufacturers. In order to establish their own brands, many drug manufacturers often register unique trade names for their drugs to distinguish them. Therefore, the same drug can have multiple trade names. For example, the trade names of acetaminophen compound preparations include Baifuzhi, Tylenol, and Biliton. When patients take medicine, no matter what the product name is, they must look for the generic name, which is the legal name of the medicine, which is also the name of the medicine stipulated in national standards.

According to the "Trademark Law", generic names cannot be registered as trademarks or trade names, so generic names can help identify medicines and avoid duplication of medicines. The "Drug Administration Law" and the "Regulations on the Administration of Drug Instructions and Labels" stipulate that the generic name of the drug should be marked on the drug package or on the drug insert. The trade name of a drug shall not be written together with the generic name, its font and color shall not be more prominent and conspicuous than the generic name, and its font shall not be larger than one-half of the font used for the generic name in terms of single character area?
