Extension: The international generic name of drugs is called the international generic name, which is an international common name. It was formulated and popularized by the World Health Organization (WHO) to facilitate medical workers, patients and pharmaceutical manufacturers to use a unified drug name in different countries and regions. Usually, the name of a drug is related to its chemical structure and pharmacological action.
Due to the long patent protection period of drugs, the same drug often has different trade names and brand names in different countries, which brings troubles to medical staff and patients. Using store names can avoid confusion and misuse caused by different trade names and brand names.
