近三十年来,随着药理学、生理生化学、免疫学等学科研究的迅速进展,新药的研制取得了很大的成果。目前世界上单一药物至少在4500种以上,且仍以平均每年增添20～30种新药的速度递增中。这些药物中药理作用基本相同、化学结构相似的品种也很多,如抗组胺作用的乙醇胺类药物有12种,乙二胺类药物有13种,肾上腺素能β受体阻滞剂已有20多种,吩噻嗪类的抗精神病药也有20余种。不仅是品种数量多,同一药效的结构类似物也多,而且,每一种药物由于生产厂商不同又有不同的商品名称。据不完全统计,苯海拉明的商品名称有40个,苯妥因钠的商品名称有65个,四环素的有75个,黄体酮的高达94个,维生素 B_1的商品名竟有177个!这些商品名称的定名,有的是随心所欲,有的则大同小异,使人眼花缭乱,难以记忆与区分。也就是在这样的背景情况下促进了“国际非专利商标药名”的产生。
In recent thirty years, with the rapid progress in the research of pharmacology, physiology and biochemistry, immunology and other disciplines, great achievements have been made in the development of new drugs. At present there are at least 4,500 single drugs in the world and the average annual increase rate of 20 to 30 new drugs is still increasing. Pharmacological effects of these drugs are basically the same, there are many chemical structure similar varieties, such as anti-histamine effects of ethanolamine drugs 12, ethylenediamine 13, adrenergic β-blockers have 20 A variety of phenothiazine antipsychotics also have more than 20 species. Not only the number of varieties, the same efficacy of structural analogs and more, and each drug because of different manufacturers have different product names. According to incomplete statistics, there are 40 names of diphenhydramine, 65 of the names of phenytoin sodium, 75 of tetracycline, 94 of progesterone and 177 of vitamin B_1! The naming of these product names, some arbitrary, while others are more or less the same, dazzling, difficult to remember and distinguish. That is to say, under such a background situation, the promotion of the “international generic drug trademark name” has been promoted.
