Common names and trade names of drugs in pharmacies 1

Common names: refers to the common names of drugs in China. The legal names of drugs are formulated by the Pharmacopoeia Commission in accordance with the "Principles for Naming Common Names of Drugs" and reported to the Ministry of Health for filing. They are the same ingredients. Or the common name of medicines with the same formula in China, which 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.

Also known as the international nonproprietary name (INN), it is the name recommended by the World Health Organization. INN usually refers to the active pharmaceutical substance rather than the final drug. Therefore, a drug only has one generic name, which is more convenient to use than a trade name.

For example, aspirin, propranolol, ibuprofen, etc.

Trade name: It 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. Generally speaking, drugs with the same generic name have the same active ingredients.

Usually it is for the final product of the drug, that is, a drug containing one or more active pharmaceutical ingredients with a determined dosage and dosage form. Like trademarks, they can be registered and applied for patent protection. Represents the image of pharmaceutical companies and the reputation of their products.

For example, Naofukang, Gankang, Isatis root, etc.

Chemical name: It is named according to its chemical structural formula, with a parent as the basic structure, and then the positions and names of other substituents are marked.

For example, N-(4-hydroxyphenyl)acetamide. Common names and trade names of drugs in pharmacies 2

Common names refer to the names of drugs formulated by the Chinese Pharmacopoeia Commission in accordance with the "Chinese Drug Common Name Naming Principles". The name of the medicine is printed on the packaging of the medicine.

Drug names are divided into common names and trade names. The common name is a unified name stipulated by the state. The common name of the same kind of medicine must be the same. Trade names are names given by different pharmaceutical manufacturers to their own preparation products, and are registered and have exclusive rights. Therefore, preparations of the same drug produced by different pharmaceutical companies often have different trade names. For example, acetaminase (common name) is an antipyretic drug, and different pharmaceutical companies produce its preparations under trade names such as Tylenol, Baifuzhi, and Biliton.

The drug names formulated by the Chinese Pharmacopoeia Commission in accordance with the "Chinese Common Drug Name Naming Principles" are called Chinese common drug names. The characteristic of a generic name is its universality, that is, it can be used by the same drug no matter where it is produced.

The common name of a drug strives to reflect the essence of the drug, and the name should be scientific, clear, and short. The generic name can reflect the main chemical ingredients of the drug to a certain extent, such as acetaminophen, hydrochlorothiazide, sulfadiazine, glipizide, etc.

If the drug preparation contains two or more ingredients, and if all the drug names cannot be abbreviated, add the word compound before the ingredient that can be abbreviated, such as compound acetaminophen, compound Daqing leaf, compound licorice Films etc.

The trade name of a drug refers to the exclusive name of a drug approved by the national drug regulatory department and used by a specific company, such as Losec (trade name) produced by AstraZeneca. ), Aifeile produced by Shandong Xinhua Pharmaceutical.

Trade names are easier to remember and pronounce than generic names, but there is a phenomenon of one drug having multiple names, such as Gankang and Crack, the generic names of which are Compound Paracetamol; Prozac and Omelon. They appear to be different drugs on the surface, but the common names are fluoxetine hydrochloride capsules.

If drug users do not know the ingredients of the drug, serious consequences such as repeated use of drugs, contraindications, and allergic reactions may occur. For the sake of drug safety, the Ministry of Health's Prescription Management Measures stipulate that starting from May 1, 2007, doctors must use the generic name of the drug when issuing prescriptions.

The trade names of some drugs are trademark names, which are trademark names registered by pharmaceutical manufacturing or operating companies for their own products in order to establish their own image and brand. Now the country has strict restrictions on the use of trade names, stipulating that drugs that fall under the following circumstances can apply for the use of trade names: ① New chemical structure, new active ingredient and during the protection period, transition period or monitoring period Drugs within: ② Drugs that have compound patents in my country and the patents are within the validity period.

In order to encourage the research and development of new drugs and protect the interests of developers, all countries protect new drugs. The protection period for international drugs is generally 20 years, the longest for domestic drugs is 10 years, and the transition period is 5 years. , the monitoring period is calculated from the date of approval for production of the new drug, and the maximum period shall not exceed 5 years.

If domestic drugs are within the protection period, transition period and monitoring period, the State Food and Drug Administration will not approve the production, change of dosage form or import by other companies.

To check the trade names of drugs, you can go to the basic data on the SFDA website. There are currently more than 7,000 trade names of domestic drugs and more than 6,000 trade names of imported drugs. These data are dynamic and change with the trade names. Approvals and drug import status are updated regularly. It should be noted that more than 7,000 trade names do not mean more than 7,000 medicines, because different dosage forms and different specifications of the same medicine can use the same trade name. For example, Shandong Xinhua Pharmaceutical’s Baihongyou (clarithromycin) has 4 records, namely tablet (0.25g), granule (1.0g: 50mg), granule 2.0g: 0.1g) and capsule (0.125g) ) Common names and trade names of drugs in pharmacies 3

There are usually four types of drug names: chemical name, common name, alias and trade name.

Chemical name: It is named based on the exact chemical structure of the drug and is very scientific. In practical applications, chemical names are mostly used in professional fields, and their value is mainly reflected in academic aspects.

Common name: It is the legal name of the drug approved by the State Food and Drug Administration, which is consistent with the internationally common drug name, the name in the Chinese Pharmacopoeia and the drug standards issued by the State Food and Drug Administration.

Alias: Alias ??of drugs are mainly due to certain historical reasons. The name of a drug that has been used for a period of time is the customary name of the drug. Although it is not standardized, it is widely used among the people. Those engaged in drug retail work should know the aliases of commonly used drugs. For example, the alias of acetaminophen is paracetamol, and the alias of norfloxacin is norfloxacin.

Alias ??names for drugs are not restricted by use or protected by law. In accordance with the regulations of the State Food and Drug Administration, the alias has been discontinued from January 1, 2007.

Trade name: It is named by pharmaceutical companies or drug research and development companies for the purpose of marketing and distribution of drugs and protecting intellectual property rights, and has been registered and filed with the Administration for Industry and Commerce. A drug may have many trade names due to different manufacturing companies, preparation processes, trademark registrations, dosage forms and specifications.

The familiar drug names of Biliton, Baifuning and Tylenol are actually the same drug. Their common name is acetaminophen, its alias is paracetamol, and its chemical name is N- (4-Hydroxyphenyl)acetamide. The most important thing to us is the generic name of the drug. A drug can have many trade names, but only one generic name. Therefore, you should read the drug instructions carefully before taking the medicine. The generic name and trade name of the drug will be clearly marked in the instructions, so as to avoid unnecessary harm caused by repeated use or misuse of the drug.
